- Added optional FetchImpl fields to compaction, proxy, AI, coding-agent, and mnemopi options.
- Threaded injected fetch implementations through OAuth, discovery, and search/LLM request flows.
- Removed exported hookFetch utility and its package entrypoint from utils.
- Replaced global-fetch test monkeypatching with per-test FetchImpl mocks across test suites.
- Forced authenticated ask requests to `experimental`, matching the anonymous fallback since the cookie session ignores pro upgrades.
- Kept TUI collapsed search answers full; capping now only applies in compact mode via `maxAnswerLines`.
- Preserved full multiline task pending preview instead of bounding it.
- Sent the OAuth token as `__Secure-next-auth.session-token` cookie since the ask endpoint ignores bearer headers and silently downgrades to `turbo`.
- Fell back to `result.title` when web results omit `name`.
- Renamed `callPerplexityOAuth` to `callPerplexityAsk` and removed a stray brace.
- Added tests covering OAuth, API-key, and anonymous request shapes.
- Raised default search results to 20 and context size to high.
- Added related questions parsing and return_related_questions request flag.
- Added API-key request-shape tests covering defaults and parsing.
