[isaacsamual994-lang]

Summary

Fixes the indefinitely-loading GET screens covered by #70 and adds manual retry feedback without silently re-submitting writes.

• Add withRequestTimeout for bounded async API reads, including JSON parsing. Use a safe default of 15 seconds, configurable via NEXT_PUBLIC_API_REQUEST_TIMEOUT_MS (1–120000 milliseconds) or a per-request timeoutMs option. Document this in both .env.example templates and docs/frontend-api-timeouts.md.
• On deadline, reject with actionable ApiRequestTimeoutError and abort the underlying fetch. On component unmount or filter/wallet changes, cancel with a distinct AbortError. A late response cannot settle the timeout wrapper even when the underlying transport ignores abort.
• Apply this to the read-only Discover Bounties (/api/tasks) and My Submissions (/api/my-submissions) screens. Add a visible loading status and user-triggered Retry loading bounties / Retry loading history options without losing filters, pagination or connected-wallet context.
• This is deliberately a read-only UI change; no automatic retries are added to POST or other state-changing operations.

Verification (local macOS)

• PASS: 25/25 focused Vitest 4.1.10 tests in a lightweight isolated mirror of the exact changed request-timeout.ts, request-timeout.test.ts, BountyList.tsx, and BountyList.test.tsx files: 22 timeout/configuration/cancellation/retry tests and 3 UI markup tests. The UI test setup used real React/ReactDOM with simple stand-ins for existing design-system primitives.
• PASS: isolated strict tsc --noEmit for the exact changed timeout utility, bounty hook, bounty list and corresponding tests, with lightweight UI stubs and the repository's actual task-workflow types.
• PASS: TypeScript parsing of all seven changed .ts/.tsx files, including both pages, with transpileModule diagnostics (syntax check, not a substitute for full app typecheck).
• PASS: git diff --check and clean committed working tree.
• Not yet verified: the full frontend workspace test suite, app-wide typecheck, ESLint or production build. The dependency install did not complete in the local Mac session.
• GitHub Actions: upstream Frontend CI and Dependency Vulnerability Scan are action_required for this fork PR, awaiting the maintainers' approval to execute. No CI result is claimed.
