fix(tui): let typing exit idle voice mode

[gnanam1990]

Summary

• exit idle /voice mode when the first ordinary printable key is typed
• preserve that first key so the prompt continues normally and subsequent spaces are inserted
• clarify the voice-mode notice and add an end-to-end key-dispatch regression test

Fixes #936

Root cause

Voice mode claimed Space for the recording gesture, but every other printable key continued into the composer. A normally typed prompt therefore lost all spaces and could trigger stray recordings/transcriptions.

Validation

• make fmt-check
• go vet ./...
• go test ./internal/tui -count=1
• focused voice-mode tests under go test -race
• go run ./cmd/zero-release build
• go run ./cmd/zero-release smoke
• make lint-static
• make vulncheck
• git diff origin/main...HEAD --check

A real terminal screenshot of the final validation is ready locally and will be attached after browser upload permission is enabled.

Summary by CodeRabbit

• New Features

  • Voice mode now exits when you begin typing, while preserving the typed input.
  • Typing or running /voice clearly disables voice mode.
  • Voice mode can still be enabled normally with the /voice command.
  • Clipboard image handling remains available through Cmd+V while voice mode is active.

• Improvements

  • Composer cursor behavior is smoother across activity, idle periods, and focus changes.
  • Agent runs now wait for required tools and session setup to be ready.

Walkthrough

Voice mode now exits on ordinary typing while preserving the triggering character. Typed /voice commands from that exit path remain disabled. Composer cursor blinking uses managed timers. Agent turns wait for tool readiness and receive per-turn session providers.

Changes

TUI behavior and turn execution

Layer / File(s)	Summary
Voice mode typing behavior internal/tui/dictation.go, internal/tui/model.go, internal/tui/composer.go, internal/tui/dictation_voice_test.go	Idle voice mode exits on printable input and preserves the input. Typed /voice does not immediately re-enable voice mode after this exit path. Normal /voice submission still enables voice mode. Notices, composer reset behavior, and tests cover these cases.
Managed composer cursor lifecycle internal/tui/model.go	Composer cursor blinking uses sequence-gated timers. Activity and focus re-arm blinking. Blur stops scheduling. Idle settling keeps the cursor visible.
Per-turn execution setup internal/tui/model.go	Agent execution waits for configured tool readiness. A new per-turn session provider is passed to agent options when configured.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to dae46

This localized TUI change exits idle voice mode when ordinary text is typed while preserving the first key; no actionable merge-blocking risk remains after normal checks and review.

I found issues that need to be addressed before this is ready.

Findings

• [P2] Keep the typed /voice command from re-enabling voice mode
  internal/tui/model.go:1627
  When voice mode is on, the new early key-dispatch branch treats the first / as ordinary typing: it calls toggleVoiceMode, so the mode is off, and then it preserves / in the composer. The rest of /voice typing falls through normally, but Enter calls handleSubmit, parses the buffer into commandVoice, and the existing command handler calls toggleVoiceMode in return. That re-toggles the mode to on, so the next Space is again captured for recording instead of typing a space.

  The root cause is that the new exit transition preserves and later retriggers the explicit command without carrying the "exited by typing" context through command dispatch. Please ensure that a /voice submitted from this new exit path leaves voiceModeEnabled false, while preserving the existing explicit-command toggle semantics for other entry paths. Add a regression that sends /, v, o, i, c, e, and Enter through m.Update.

• [P2] Do not consume Cmd+V as ordinary text when exiting voice mode
  internal/tui/model.go:1627
keyPrintable excludes Ctrl and Alt modifiers but not ModSuper. On a macOS terminal that delivers Cmd+V to the application, the key has text v and the new voice-mode branch matches it before the existing Ctrl+V/Cmd+V image-clipboard case. It turns voice mode off and inserts a literal v, then returns, so readClipboardImageCmd never runs. That breaks the existing supported image-paste path only while voice mode is idle.

  The root cause is that the new "ordinary typing" predicate is broader than the prior dispatch order and does not exclude Command-modified shortcuts. Please narrow the exit trigger to unmodified printable input (or otherwise let higher-priority global shortcuts route first), so Cmd+V continues to reach the image-clipboard handler while unmodified typing still exits voice mode. Add a focused test with tea.ModSuper and verify the clipboard command is returned rather than a composer insertion.
