* fix: resolve folder slugs to page data in /api/page endpoint

Folder slugs like /docs returned 404 from the page API since no page
exists at that exact path. Extract resolvePageAndSlug into tree-utils
and reuse it in both the API endpoint and SSR entry, eliminating
duplicate redirect resolution logic.

* fix: lazy-import source.ts in resolvePageAndSlug to fix test failure

import.meta.glob in source.ts is Vite-only and breaks bun test when
imported at top level from tree-utils.ts.

* refactor: static import config and version-source, only lazy-import source

Only source.ts needs lazy import due to import.meta.glob.

* fix: address PR review comments for resolvePageAndSlug

- Accept deps as params instead of dynamic import and internal loadConfig
- Pass already-resolved version from callers instead of re-deriving
- Use resolved slug for nav/frontmatter/embeddedData in SSR (fix stale pageSlug)
- Remove bare catch that swallowed all errors
- Remove redundant inline type annotations
- Add tests for resolvePageAndSlug (happy path, folder fallback, not found, draft)

node-worker runner fails on Windows due to Nitro 3 beta + Vite 8
environment API incompatibility. Fallback to node-process runner
which uses child process instead of worker threads.

* perf: reduce initial HTML payload by 30KB

- Strip unused fields ($ref, $id, description, root) from page tree
  before embedding in __PAGE_DATA__ — 54.5% tree size reduction
- Pre-filter tree by version and content dir server-side instead of
  embedding full tree and filtering on client
- Add Cache-Control headers to /api/page endpoint (1h browser, 24h CDN)

Measured on 209-page site:
  __PAGE_DATA__: 57KB → 27KB
  Total HTML: 167KB → 136KB

* fix: use endpoint templates instead of paths in metrics labels

Prevents high-cardinality metric labels in Prometheus by mapping
request paths to endpoint templates (e.g., /docs/:slug, /apis/:slug).
API routes keep their exact path (/api/page, /api/search).

* fix(ci): use in-process Nitro runner for Windows dev smoke test

node-process runner uses fork() + IPC which is flaky on Windows CI
runners — child process sometimes never sends ready signal, causing
health check to hang until job timeout.

Adds OpenTelemetry SDK logs to the telemetry plugin, emitting structured
log records to stdout for every HTTP request. Each log includes
client.address (from x-forwarded-for/x-real-ip/remoteAddress), method,
route, status code, and duration.
