fix: resolve lint warnings

[notgitika]

Summary

• Disable false-positive security rules (detect-non-literal-fs-filename, detect-object-injection) globally in ESLint config — these are expected for a CLI tool that works with dynamic file paths and Record lookups (416 warnings)
• Remove stale eslint-disable inline comments that became unnecessary after the global disables and from prior rule removals (13 files)
• Fix react-hooks/exhaustive-deps by adding missing dependencies to useEffect arrays
• Fix security/detect-unsafe-regex by rewriting the Gateway name regex and suppressing safe bounded regexes
• Suppress react-refresh/only-export-components for intentional co-located utility exports
• Suppress react-hooks/preserve-manual-memoization for stable process-lifetime memoization

Test plan

• npm run lint — 0 warnings (down from 437)
• npm run typecheck — passes
• npm run format:check — passes
• npm test — no new failures (14 pre-existing failures on main)
