* fix(core): improve ripgrep runtime reliability
Make ripgrep failures distinguishable from true no-match results so the
model avoids unsafe conclusions from partial or failed searches. Add a
narrow recovery path for confirmed worker-thread EAGAIN failures.
- Retry confirmed thread EAGAIN once with a single worker thread
- Treat exit code 1 as no-match only when both streams are empty
- Mark partial runtime results as incomplete, separate from display limits
- Add privacy-safe telemetry and focused coverage for recovery behavior
# Conflicts:
# packages/core/src/utils/ripgrepUtils.test.ts
* fix(core): restore ripgrep runtime recovery tests
Restore the runRipgrep coverage that was lost during the rebase and keep
EAGAIN detection aligned with the runtime reliability design.
- Re-add coverage for strict no-match handling and incomplete output
- Verify single-thread retry behavior for confirmed EAGAIN failures
- Keep spawn, cancellation, timeout, and max-buffer paths covered
- Treat os error 11 as the short EAGAIN marker documented by the plan
* docs(core): document ripgrep recovery boundaries
Clarify the non-obvious runtime reliability edges around ripgrep recovery so
future changes preserve the intended narrow behavior.
- Document why only confirmed worker EAGAIN failures are retryable
- Explain incomplete-output handling for interrupted ripgrep output
- Note the privacy boundary for runtime recovery telemetry
* fix(core): correct exit-1 no-match gate for --json summary output (#7888)
* test(core): remove duplicate mockReset and add telemetry coverage (#7888)
* fix(core): address review feedback on ripgrep recovery semantics (#7888)
- Fix stale `truncated` property in test mock to match RipgrepRunResult
- Narrow `incomplete` flag to genuinely interrupted executions only
- Add test for exit code 1 with both stdout and stderr
- Add test for EAGAIN retry producing partial stdout
- Alias RipgrepRuntimeRecoveryFailureKind to RipgrepFailureKind
* docs(core): align exit-1 no-match spec with stderr-only gate (#7888)
* fix(core): mark exit-failed ripgrep searches with stdout as incomplete (#7888)
