Fix dashboard digit shortcuts

[TraderSamwise]

Summary

• make dashboard digit shortcuts match the currently visible entry list at session/item level
• keep worktree-level digit shortcuts scoped to visible worktrees
• remove the obsolete buffered quick-jump timeout path and update footer labels

Verification

• yarn vitest src/multiplexer/dashboard-interaction.test.ts src/tui/screens/dashboard-renderers.test.ts src/dashboard/quick-jump.test.ts
• yarn typecheck
• yarn lint
• yarn vitest
• AIMUX_RELEASE_VERSION=0.1.21-local-smoke53 yarn release:asset && scripts/install.sh release/aimux-darwin-arm64.tar.gz
• manual TUI smoke: digit 6 opens shell service, service restore/stop settles cleanly

Summary by CodeRabbit

• New Features

  • Numeric shortcuts now jump immediately to the selected entry or worktree, making dashboard navigation faster and more direct.
  • Shortcut hints now show clearer labels for the active level, distinguishing between entry-level and worktree-level actions.

• Bug Fixes

• Tests

  • Added coverage for numeric shortcut handling at both session and worktree levels.

📝 Walkthrough

Walkthrough

Removes the buffered multi-digit quick-jump mechanism (timeout constant, class field, commitDashboardQuickJump, auto-commit on non-digit key) and replaces it with immediate single-digit navigation in handleDashboardQuickJumpDigit. Footer hint labels for 1-9 keys are updated from "jump" to "entry" or "worktree" depending on nav level.

Immediate single-digit quick-jump navigation

Layer / File(s)	Summary
Remove timeout constant and class field src/dashboard/quick-jump.ts, src/multiplexer/index.ts	Deletes DASHBOARD_QUICK_JUMP_TIMEOUT_MS and HOTKEY_TIMEOUT_MS import, and removes the dashboardQuickJumpTimeout private field from Multiplexer.
Rewrite handleDashboardQuickJumpDigit to immediate navigation src/multiplexer/dashboard-interaction.ts	Switches to standalone import for buildDashboardQuickJumpWorktrees, rewrites clearDashboardQuickJump to reset digits only, rewrites handleDashboardQuickJumpDigit for immediate single-digit action at sessions or worktrees level, expands handleDashboardKey break condition for digit keys, and removes auto-commit of buffered digits.
Update footer hint labels and tests src/tui/screens/dashboard-renderers.ts, src/tui/screens/dashboard-renderers.test.ts	Changes 1-9 hint label from "jump" to "entry" at sessions level and "worktree" at worktrees level, with a new test asserting both values.
Tests for immediate digit navigation src/multiplexer/dashboard-interaction.test.ts	Adds session-level digit test verifying sessionIndex update and entry activation, and worktree-level digit test verifying focusedWorktreePath and renderDashboard call.

Poem

🐇 No more waiting, no more delay,
One digit pressed and you're on your way!
The timeout vanished, the buffer is gone,
Jump to your entry and carry on.
Hop! 🥕
