tiennm99 bdbcc43f85 chore(tooling): golangci-lint + govulncheck + defensive guards
Phase 6 of the 2026-05-09 review remediation plan. Bundle of small
hygiene fixes — none individually urgent but better folded together
than scattered across follow-ups.

- .golangci.yml: enable errcheck/govet/gosec/staticcheck/unused/
  ineffassign/gocyclo/misspell/revive. Tuned to the codebase style
  (no universal exported-doc requirement, gocyclo cap at 20 to
  accommodate handler dispatch). 0 issues across the tree.
- ci.yml: add golangci-lint job + govulncheck (informational).
- Defensive guards:
  - registry.go: Module.Name mismatch now errors at Build instead of
    silently overwriting (TestBuild_RejectsFactoryNameMismatch).
  - cmd/server/main.go: PORT env validated numerically + 0..65535.
  - firestore_provider.go: For() re-validates module name; invalid
    names return an invalidStore whose every op errors with
    ErrInvalidModuleName.
- Dead code removal:
  - wordle: gameTTLSeconds const + pickDaily/hashDJB2/todayUTC
    helpers + their tests deleted (pickDaily was unused;
    daily.go renamed pick_random.go).
- Dependency: golang.org/x/net v0.52.0 -> v0.54.0 (resolves
  GO-2026-4918 HTTP/2 infinite-loop CVE).
- Deferred from the original phase plan: Docker digest pinning
  (Dependabot handles), per-handler file splits (largest file 279 LOC;
  splits would churn for marginal gain).

go test -race -count=1 ./... clean (15 packages); golangci-lint run
clean (0 issues).
