Fixes#5178

- Removed vibe tools from the default global tool registry, preventing unnecessary background exposure.
- Offloaded slow LSP diagnostics to a deferred channel in the `write` tool to prevent blocking agent execution for the full 3-second poll window.
- Abstracted deferred diagnostic logic into a reusable `DeferredDiagnostics` class to standardize tracking and deduplication across tools.
- Updated `WriteTool` to support `beginDeferredDiagnosticsForPath` callbacks, surfacing diagnostics as an aside instead of stalling the tool result.
- Added a regression test validating that `write` completes immediately while diagnostics arrive asynchronously.

Fixes#5135
- Ran commit host completion before commit-agent session disposal so mnemopi/autolearn teardown cannot preempt a valid proposal.
- Converted missing commit-agent host outputs and split-plan gaps into thrown errors so omp commit cannot resolve into exit 0 without creating a commit.
- Preserved caller GPG_TTY state instead of forcing a bogus signing TTY in git and non-interactive subprocess environments.
Fixes#4794
Emitted a failed auto-retry event when empty assistant stop responses exhaust their retry cap so the TUI can show an error instead of silently settling.
Fixes#5128
- Applied the known reasoning envelope filter when deciding whether a title marker is visible.
- Added title extraction regressions for reasoning tag and reasoning fence envelopes before the visible title.
