- Add `snapshotSession(sessionId)` to inspectorSessions.ts per master-plan §3.8:
returns parsed InterceptedRequest[] in seq order, or null for non-existent sessions.
Silently skips rows that fail InterceptedRequestSchema validation (defensive).
- Restore canonical no-arg form of `MitmHandlerBase.hookBufferUpdate(intercepted)`
per master-plan §3.5: when opts is omitted, derive completion fields from
the intercepted object itself (status/responseHeaders/responseBody/responseSize/
*LatencyMs) rather than no-op'ing. Extended opts form preserved for legacy callers.
- Update Zod record() calls in InterceptedRequestSchema to current (key,value) signature.
- Add 3 unit tests for snapshotSession (happy path / non-existent / silent skip).
- Add 2 unit tests for hookBufferUpdate (no-arg form + extended opts form).
