Claude 0918f859a0 test: close measured test-coverage gaps across server, client and Rust
Audits what actually has tests, then closes the gaps it found. Full write-up
with before/after numbers in docs/audit-test-coverage-2026-07-25.md.

Measurement first: `go test ./... -coverprofile` (what CI runs) instruments
each package only for itself, so code exercised through another package's
tests reads as uncovered — `service` reported 36.7% against a real 85%. All
analysis here uses -coverpkg=./..., and both views now have Makefile targets.

Features that had zero coverage at every layer:
- user blocking (db + service + the /api/v1/blocks routes)
- auth lockout persistence — the DB round-trip that survives a restart
- plugin install/enable/disable/uninstall and the plugin KV namespace
- event replay bounds (GetMaxEventSeq, PruneEventsOlderThan)
- LiveKit participant_joined webhook (replayed-token guard), the room-service
  client, and proxyWebSocket/copyWS
- ws_proxy.rs and livekit_proxy.rs — pure helpers extracted, matching the
  existing tofu.rs pattern, so cert-pin and header-injection checks are testable

Gaps that were hidden rather than absent:
- Server/admin reported 0.3% coverage with 307 tests passing. TestSpawnDetached_*
  re-execs the test binary; the child inherited GOCOVERDIR and the parent's
  stdout, clobbering the profile and printing "[no tests to run]". Now 71.4%,
  and CI's uploaded artifact is correct.
- vitest.config.ts excluded 2.2k LOC unexplained, including two files that
  already had tests. Trimmed to three entries, each justified inline.
- api.HandleLiveKitHealthForTest re-implemented the handler it claimed to
  expose, so eight call sites tested a copy. Added a hook to the real one.

Two bugs found and pinned rather than silently patched: logctx.WithGroup nests
req_id under the group, and drag-reorder.ts takes one listener ref per channel
but releases one per sidebar, so the count never reaches zero.

Coverage: client 92.93% -> 94.87% statements (3371 -> 3572 tests) even after
un-excluding hidden files; Rust 47 -> 74 tests; Go zero-coverage functions
~70 -> 21, with plugin 61->77%, admin 67->86%, db 76->84%, service 85->91%.

Verified: go vet, all four build-tag variants, go test -race, -tags deadlock,
vitest --coverage, cargo test --lib, cargo clippy --all-targets, playwright.
