perf(cli): defer startup prefetch tasks (#6303)
* perf(cli): defer startup prefetch tasks

* fix(cli): await IDE for prompt-interactive startup

* perf(cli): defer interactive telemetry startup

* test(cli): add missing assertions and Zed/ACP path coverage for startup prefetch

Address three test coverage gaps identified during code review:

- Assert mockStartEarlyStartupPrefetches in both kitty protocol tests
  (C1: API preconnect call was wired but never verified)
- Add Zed/ACP integration test verifying deferIdeConnection is false
  when getExperimentalZedIntegration returns true (C2: Zed path was
  entirely untested)
- Assert mockStartBackgroundHousekeeping in startup-prefetch test
  (C3: unconditional housekeeping dispatch was never verified)

* docs: move startup prefetch design doc to performance subdirectory

* docs: translate startup prefetch design doc to English

* fix(cli): address startup prefetch review comments

Tighten the startup prefetch follow-up fixes from review while keeping
prompt-interactive telemetry on the fast interactive startup path.

- Preserve Error objects when deferred startup tasks fail
- Remove the unbalanced api_preconnect profiler lifecycle event
- Guard background housekeeping so it only runs for interactive configs
- Document and test prompt-interactive telemetry deferral semantics

* fix(cli): initialize telemetry for prompt-interactive prompts

Ensure sessions launched with an initial interactive prompt have
telemetry ready before the auto-submitted first request runs.

- Exclude prompt-interactive startup from telemetry deferral
- Pass a post-render telemetry option through interactive UI startup
- Skip duplicate post-render telemetry startup for initial prompts
- Update tests to cover the first-prompt telemetry guarantee

Note: Plain interactive TUI startup still defers telemetry post-render.

* fix(cli): preserve startup first-request guarantees

Keep deferred startup work from weakening first-request behavior in
interactive sessions that submit prompts automatically or remotely.

- Store telemetry deferral on Config and reuse that decision at render time
- Keep IDE startup awaited for prompt-interactive and input-file sessions
- Add a timeout for deferred IDE connection failures
- Cover ordinary interactive telemetry deferral and IDE startup edge cases

* fix(cli): make post-render IDE connection opt-in

Default startInteractiveUI to the already-connected IDE path so future
callers do not accidentally connect twice when initializeApp used its
eager default.

- Change the post-render IDE connection default to false
- Update startInteractiveUI tests to assert the safer default

* perf(cli): surface deferred IDE connection status

Make ordinary interactive IDE startup visible while preserving the
post-render prefetch path and first-paint performance tradeoff.

- Emit deferred IDE connection lifecycle events for connecting, success,
  and failure states
- Surface IDE startup status in the TUI footer without blocking input
- Log late underlying IDE failures after timeout for better diagnostics
- Document telemetry deferral tradeoffs and add startup lifecycle tests
