chore(lint): enable eqeqeq rule

[mkczarkowski]

What changed

Enables the already-clean eqeqeq rule at error level and refreshes the generated repository map.

Why

This is the first bounded overnight lint ratchet. The rule currently reports no violations, so enabling it prevents future loose-equality regressions without requiring source changes.

Recovery note

The unattended runner initially stopped on repo-map freshness and opened issue #13. The preserved worktree was repaired by regenerating the map once with the fully installed toolchain; two consecutive freshness checks then passed. No scope was broadened.

Validation

• git diff --check
• bun run typecheck
• bun run lint — 2 pinned warnings / 0 errors
• loopback-only, external-network-denied unit gate — 469 pass / 0 fail
• bun run build
• bun run examples:catalog:check
• bun run repo-map:check — passed twice consecutively

Scope: .oxlintrc.json plus generated context/map files only. This PR targets claude/context-loops-bootstrap, not master.
