feat(mobile): show lightweight running terminal indicators

[Adamulek123]

What Changed

• Show a continuously pulsing terminal status on mobile thread cards and thread headers while terminal sessions are running.
• Use one shared, low-frequency stepped pulse so animation work stays independent of 120 Hz/360 Hz display refresh rates.
• Render the same Tabler terminal glyph on iOS and Android, with truthful accessibility labels and reduced-motion support.

Why

Running terminal sessions were easy to miss on mobile, while a conventional continuously interpolated animation could keep repainting at the display refresh rate and waste GPU time. This keeps the requested always-on motion but reduces animation updates to eight opacity steps per roughly 1.9-second cycle and shares the animated value across indicators.

Validation

• �p run --filter @t3tools/mobile typecheck`n- Targeted �p lint for touched TypeScript files
• �p fmt --check for touched files and docs
• �p test run apps/mobile/src/features/terminal/terminalRunningStatus.test.ts (4 passed)
• git diff --check`n- Device verification not run: Android SDK is unavailable on this Windows host; iOS Simulator requires macOS.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes
• I included a video for animation/interaction changes

Generated with GPT-5.6 Sol in the Codex harness through T3 Code.

Note

Add pulsing terminal running indicators to mobile thread list and headers

• Introduces TerminalRunningIndicator and StatusPulse to show a pulsing terminal icon when terminal sessions are running, respecting the system reduced-motion setting.
• Adds countRunningTerminalSessions, terminalRunningSessionLabel, and useThreadRunningTerminalCount to provide reactive per-thread running session counts and accessibility labels.
• Extends AppHeaderIconButton and NativeHeaderToolbar with custom and pulsing capabilities, replacing the old menu-based terminal item with TerminalHeaderMenuButton.
• Adds --color-terminal-active theme token to light (#0d9488) and dark (rgba(94, 234, 212, 0.9)) variants.
• Behavioral Change: ThreadGitControls replaces NativeHeaderToolbar.Menu with NativeHeaderToolbar.Custom for the terminal control; existing menu actions remain the same.

Note

Medium Risk
Touches native header item types and a shared Reanimated pulse used across lists and toolbars, so header chrome and animation behavior can regress, but it does not change auth or data handling.

Overview
Shows when a thread has a running terminal process on mobile: a teal pulsing terminal glyph on list rows and the thread header, with matching accessibility labels.

Adds a shared StatusPulse (stepped opacity, one loop for all indicators, reduced-motion off) plus --color-terminal-active. The terminal glyph always uses Tabler so iOS and Android match.

The header terminal control is now a custom pulsing button wrapping the existing scripts/sessions menu (NativeHeaderToolbar.Custom). Running counts come from terminal metadata via useThreadRunningTerminalCount.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a new user-facing feature with new animation components, hooks, and integrations across multiple screens (thread lists, headers). New capabilities with cross-cutting UI changes warrant human review.
