Move docs/ package mirror into document-navigator plugin

Relocate the ~6k-file docs tree from the repo root into
plugins/document-navigator/docs/ so the plugin is self-contained and
portable. docs/superpowers/ (specs and plans) stays at the repo root.

Moved via cp+rm rather than git mv because directory rename() fails with
EPERM on this WSL /mnt DrvFs mount; git rename-detection pairs the
identical-content files at commit time.

+Universal Mollie Payments API v2 adapter for `@suaveplan/payment`.
+Sibling provider package on the slim `@suaveplan/payment-providers`
+core: implements `PaymentProvider` with Mollie's string-amount
+marshalling (`{ currency, value: "X.YY" }`) round-trip via the
+exported `formatMollieAmount` / `parseMollieAmount` helpers.

+## Install
+
+```bash
+bun add @suaveplan/payment-provider-mollie @suaveplan/payment-providers @suaveplan/payment
+```
+
+## Quick start
+
+```ts
+import { ProviderRegistry } from "@suaveplan/payment-providers";
+import { MollieProvider } from "@suaveplan/payment-provider-mollie";
+
+const registry = new ProviderRegistry();
+registry.register(
+    new MollieProvider({ apiKey: process.env.MOLLIE_API_KEY ?? "" })
+);
+
+const mollie = registry.get("mollie");
+const intent = await mollie.createIntent({
+    amount: { amount: 5000n, currency: "EUR" },
+    description: "Order #42",
+    returnUrl: "https://shop.example/return",
+});
+console.log(intent.id, intent.status);
+```
+
+## Features
+
+- `MollieProvider` — full `PaymentProvider` lifecycle
+  (`createIntent`, `confirmIntent`, `captureIntent`, `cancelIntent`,
+  `refund`, `getIntent`) on top of the slim `httpRequest` helper.
+- Pure, exported amount helpers — `formatMollieAmount(amount: bigint)`
+  and `parseMollieAmount(value: string)` — that round-trip losslessly
+  via `bigint` and cover the 1-cent, exact-major, large-value, and
+  over-precision edges.
+- Total exported status maps — `mapMollieStatus` and
+  `mapMollieRefundStatus` — each individually unit-testable without
+  invoking the network path.
+- `Authorization: Bearer <apiKey>` header auto-applied on every call.
+- Universal — no Node-specific or browser-specific globals; runs
+  on Node 18+, Bun, browsers, and Web Workers.
+- All failures surface as `PaymentProviderError` from
+  `@suaveplan/payment-providers` carrying a `PAYMENT_PROVIDER_*` code.
+
+## Modules
+
+- [`src/mollie/mollie.md`](./src/mollie/mollie.md) —
+  `MollieProvider` class, helpers, and status maps.
+
+## Sibling packages
+
+Part of the `@suaveplan/payment-provider-*` family. See
+[`@suaveplan/payment-providers`](../payment-providers/README.md) for the
+shared foundation (`ProviderRegistry`, `httpRequest`,
+`composeAbortSignal`, `PaymentProviderError`, the `PAYMENT_PROVIDER_*`
+code registry, and the shared config shapes).

+# MollieProvider
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+
+## Purpose
+
+`MollieProvider` is the sibling adapter that implements the
+`PaymentProvider` contract from `@suaveplan/payment` against the Mollie
+Payments API v2. It is the only `@suaveplan/payment-provider-*` sibling
+that has to marshal money amounts to and from a string representation:
+every Mollie request and response carries amounts as
+`{ currency: "EUR", value: "10.00" }`, while the rest of the suaveplan
+payment family models money as `bigint` minor-units. This package
+owns that round-trip end-to-end and exposes the underlying helpers
+(`formatMollieAmount`, `parseMollieAmount`) so callers can test or reuse
+them in their own integrations.
+
+## Features
+
+- `MollieProvider` class implementing `PaymentProvider` with name
+  `"mollie"`.
+- Constructor takes `ApiKeyConfig` from `@suaveplan/payment-providers`
+  (`apiKey`, optional `baseUrl`, `timeoutMs`, `fetch`, `signal`,
+  `webhookSecret`).
+- Auto-sets `Authorization: Bearer <apiKey>` on every call.
+- Uses the slim-core `httpRequest` helper for JSON serialisation,
+  per-call timeout, external `AbortSignal` composition, and typed
+  error surfacing.
+- Defaults `description` to `"Payment"` and `redirectUrl` to
+  `"https://localhost/return"` when omitted, matching upstream
+  behaviour.
+- `confirmIntent` and `captureIntent` are read-throughs to `getIntent`
+  because Mollie auto-captures.
+- Pure, exported amount helpers (`formatMollieAmount`,
+  `parseMollieAmount`) and status maps (`mapMollieStatus`,
+  `mapMollieRefundStatus`) — all individually unit-testable.
+- All failures surface as `PaymentProviderError` carrying a
+  `PAYMENT_PROVIDER_*` code; raw `Error` is never thrown.
+
+## Usage: Basic Example
+
+```ts
+import { ProviderRegistry } from "@suaveplan/payment-providers";
+import { MollieProvider } from "@suaveplan/payment-provider-mollie";
+
+const registry = new ProviderRegistry();
+registry.register(new MollieProvider({ apiKey: process.env.MOLLIE_API_KEY ?? "" }));
+
+const mollie = registry.get("mollie");
+const intent = await mollie.createIntent({
+    amount: { amount: 5000n, currency: "EUR" },
+    description: "Order #42",
+    returnUrl: "https://shop.example/return",
+});
+console.log(intent.id, intent.status);
+```
+
+## Usage: Advanced Example
+
+```ts
+import { MollieProvider, formatMollieAmount, parseMollieAmount } from "@suaveplan/payment-provider-mollie";
+import type { FetchLike } from "@suaveplan/payment-providers";
+
+// Inject a recording FetchLike for tests — no global monkey-patching.
+const recorded: { url: string; init?: RequestInit }[] = [];
+const recordingFetch: FetchLike = async (url, init) => {
+    recorded.push({ url, init });
+    return new Response(JSON.stringify({
+        id: "tr_xyz",
+        status: "paid",
+        amount: { value: "12.34", currency: "EUR" },
+        createdAt: "2026-01-01T00:00:00+00:00",
+    }), { status: 200, headers: { "content-type": "application/json" } });
+};
+
+const provider = new MollieProvider({
+    apiKey: "test_xyz",
+    baseUrl: "https://mollie.mock/v2",
+    timeoutMs: 5_000,
+    fetch: recordingFetch,
+});
+
+// Round-trip amount marshalling without hitting the network:
+const wire = formatMollieAmount(1234n); // "12.34"
+const back = parseMollieAmount(wire);   // 1234n
+
+// Drive the full lifecycle for assertions:
+const intent = await provider.createIntent({
+    amount: { amount: 1234n, currency: "EUR" },
+});
+const captured = await provider.captureIntent(intent.id); // read-through
+const refund = await provider.refund({
+    paymentIntentId: intent.id,
+    amount: { amount: 1234n, currency: "EUR" },
+});
+```
+
+## API Reference
+
+### `MollieProvider`
+
+- `new MollieProvider(config: ApiKeyConfig)` — constructs the adapter.
+  `config.apiKey` is required; `baseUrl`, `timeoutMs`, `fetch`,
+  `signal`, and `webhookSecret` are optional. `baseUrl` defaults to
+  `MOLLIE_DEFAULT_BASE_URL`; `timeoutMs` defaults to `30_000`.
+- `name: "mollie"` — literal-typed instance field.
+- `createIntent(input: CreatePaymentIntentInput): Promise<PaymentIntent>` —
+  POST `${baseUrl}/payments`. Defaults `description` and `redirectUrl`
+  when omitted.
+- `confirmIntent(intentId: string): Promise<PaymentIntent>` —
+  read-through to `getIntent`.
+- `captureIntent(intentId: string): Promise<PaymentIntent>` —
+  read-through to `getIntent` (Mollie auto-captures).
+- `cancelIntent(intentId: string): Promise<PaymentIntent>` — DELETE
+  `${baseUrl}/payments/${intentId}`.
+- `refund(input: RefundInput): Promise<Refund>` — POST
+  `${baseUrl}/payments/${intentId}/refunds`. Omits the body's `amount`
+  field when `input.amount` is undefined (Mollie issues a full refund).
+- `getIntent(intentId: string): Promise<PaymentIntent>` — GET
+  `${baseUrl}/payments/${intentId}`.
+- Throws: `PaymentProviderError` with code
+  `PAYMENT_PROVIDER.HTTP_ERROR` / `PAYMENT_PROVIDER.TIMEOUT` /
+  `PAYMENT_PROVIDER.PARSE_ERROR`.
+
+### `MOLLIE_DEFAULT_BASE_URL: "https://api.mollie.com/v2"`
+
+Production Mollie REST v2 base URL constant.
+
+### `MOLLIE_PROVIDER_NAME: "mollie"`
+
+Stable provider identifier.
+
+### `formatMollieAmount(amount: bigint): string`
+
+Format a minor-units `bigint` into a two-decimal string. Always
+produces exactly two minor digits, pads left for sub-major values
+(`1n` → `"0.01"`), and supports negative values.
+
+### `parseMollieAmount(value: string): bigint`
+
+Parse a Mollie wire-format decimal string into a minor-units `bigint`.
+Accepts no-decimal, single-decimal, two-decimal, or over-precision
+inputs; over-precision is truncated, never rounded.
+
+### `mapMollieStatus(status: string): PaymentStatus`
+
+Total map from Mollie's payment-status string to the canonical
+`PaymentStatus` union. Unknown values fall back to `"failed"`.
+
+### `mapMollieRefundStatus(status: string): RefundStatus`
+
+Total map from Mollie's refund-status string to the canonical
+`RefundStatus` union. Unknown values fall back to `"failed"`.
+
+## Implementation Notes
+
+- The package is universal — no Node-specific or browser-specific
+  globals. The only runtime concept beyond the language standard is
+  the WHATWG `fetch` surface, available in every supported runtime.
+- Tests inject a recording `FetchLike` closure into the constructor
+  instead of mutating `globalThis.fetch`. This satisfies rule 8 (no
+  mocks) and matches the binance / ecb sibling pattern.
+- `confirmIntent` and `captureIntent` are deliberate read-throughs to
+  `getIntent`: Mollie auto-captures, so there is no separate confirm or
+  capture step at the protocol level. Returning the current state
+  preserves the `PaymentProvider` contract without falsifying the
+  underlying behaviour.
+- `formatMollieAmount` and `parseMollieAmount` are inverses for every
+  `bigint` produced from a Mollie response. Round-trip is exact for
+  zero, single cent, exact major unit, and large values up to
+  `2^53`-and-beyond range (`bigint` is arbitrary-precision; the helpers
+  never go through `number`).
+- Over-precision in `parseMollieAmount` (`"10.123"` → `1012n`) is
+  truncation, not rounding. Mollie emits exactly minor-unit precision;
+  over-precision is upstream garbage and the safest action is to
+  ignore the excess rather than to bias the result.
+- The card-brand normalisation accepts any of `visa` / `mastercard` /
+  `amex` / `discover` / `diners` / `jcb` / `unionpay`; every other
+  label collapses to `"unknown"` rather than leaking arbitrary strings
+  into the `CardBrand` union.
+- Forwarded `AbortSignal` composition (caller `signal` + per-call
+  timeout) is handled by the slim-core `httpRequest`; this package
+  does not re-implement it.
