Subject: [PATCH 1/9] feat(#312): skills marketplace x402 micro-payment flow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add x402 payment middleware for skill invocation
- Implement full flow: 402 capture → quote → settle → retry with proof
- Add invocation ledger to track all skill payments
- Add POST /api/marketplace/skills/:skillId/invoke endpoint
- Support mock mode for local development
- Add comprehensive unit tests (11+ assertions)

Closes #312
