v0.36.0-beta.13

Delta since previous beta (v0.36.0-beta.12) — 2 new changesets.

Patch Changes

• Every /api/* response now carries an x-request-id correlation header — a well-formed incoming x-request-id is honored, anything else gets a minted UUID — and the server emits one structured api.access log line per API request (method, route template, status, duration) to the on-disk log for bug-report bundles. The same ID lands on the request trace span, so a client-reported ID joins against both the logs and the trace. Verb-dispatch and error-tail plumbing inside the HTTP API was consolidated into shared helpers with no wire-shape changes.

• Persist the tag index with mtime reconcile for faster warm boots and branch switches. The tag index now snapshots to .ok/local/cache/tags.json (like the backlink cache) and re-parses only files whose mtime or size changed instead of re-reading the whole content dir on every server start and git branch switch. Backlink and tag index rebuilds also emit OpenTelemetry spans and rebuild counters/duration histograms.
