feat: add Claude theme

[HUQIANTAO]

Summary

Adds a new Claude theme aligned with Claude Code's product surface colors. Selectable from the /theme picker as the 9th preset.

Palette

Built from the Claude.com / Claude Code dark product chrome:

Role	Color	Token
Surface BG	#181715	surface-dark
Panel BG	#252320	surface-dark-elevated
Elevated BG	#1f1e1b	surface-dark-soft
Primary accent	#cc785c	coral (Anthropic signature)
Secondary accent	#5db8a6	accent-teal
Text body	#faf9f5	on-dark (cream white)
Text muted	#a09d96	on-dark-soft

Details

• 36-field UiTheme populated with the Claude design token palette
• Registered in theme_remap_active so cell-level color remap applies at render time
• All 11 WCAG contrast QA tests pass (≥4.5:1 body, ≥3.0:1 muted)
• ThemeId → ThemeId::Claude, canonical name "claude", displayed as Claude

Greptile Summary

This PR adds a Claude theme to the TUI palette (warm navy + coral, aligned with Claude Code's product surface colors) and also ships a new turn-stall watchdog that auto-recovers the UI after a 300-second "in_progress" turn with no completion signal.

• CLAUDE_UI_THEME populates all 36 UiTheme fields, is registered in SELECTABLE_THEMES and theme_remap_active, and passes the existing WCAG contrast test suite.
• Branch 3 in reconcile_turn_liveness adds TURN_STALL_WATCHDOG_TIMEOUT (300 s) to surface an error toast and reset loading state when a turn stalls without a completion event and no sub-agents are running.
• The theme_picker wrap-around test and a new turn_liveness_recovers_stalled_in_progress_turn unit test cover both additions.

Confidence Score: 5/5

Safe to merge — the theme addition is purely additive and the stall watchdog only changes UI state when a turn has been visibly stuck for 5 minutes.

The Claude theme follows every existing convention exactly, and Branch 3 is well-tested and narrowly scoped: it only fires when the UI is loading, status is "in_progress", no agents are running, and 300 s have elapsed — making accidental triggers essentially impossible in normal operation.

The inline comment for Branch 3 in crates/tui/src/tui/ui.rs claims the watchdog handles stuck sub-agents, but the !has_running_agents guard prevents it from doing so — worth clarifying before the next reader is misled.

Important Files Changed

Filename	Overview
crates/tui/src/palette.rs	Adds CLAUDE_UI_THEME constant and ThemeId::Claude variant; all 36 UiTheme fields populated, registered in SELECTABLE_THEMES and theme_remap_active — consistent with every other custom theme.
crates/tui/src/tui/ui.rs	Adds TURN_STALL_WATCHDOG_TIMEOUT (300 s) and Branch 3 in reconcile_turn_liveness to recover UI from stalled in_progress turns; docstring and inline comment claim stuck sub-agents are covered but !has_running_agents guard prevents that.
crates/tui/src/tui/ui/tests.rs	Adds turn_liveness_recovers_stalled_in_progress_turn test and updates turn_liveness_leaves_active_turn_running to use turn_started_at; both test the correct branch boundaries.
crates/tui/src/theme_qa_audit.rs	Imports CLAUDE_UI_THEME and adds it to the ALL_THEMES slice so the existing WCAG contrast tests cover the new theme.
crates/tui/src/tui/theme_picker.rs	Updates arrow-wrap test to expect ThemeId::Claude as the last theme when pressing Up from System; correct after Claude is appended to SELECTABLE_THEMES.
Cargo.toml	Workspace version bumped from 0.8.46 to 0.8.47; Cargo.lock updated to match.

   The module docstring references v0.8.45 but the workspace has been at v0.8.47 since this PR's version bump. This will accumulate misleading drift each release if not kept in sync.

Code Review

This pull request introduces a new "Claude" UI theme to the TUI, featuring a dark navy background with warm coral and teal accents. It also updates the Cargo workspace package version to 0.8.47. A review comment points out that accent_action in the new theme should be set to a distinct amber color to align with the project's theme guidelines and other community themes.

[gemini-code-assist]

In CLAUDE_UI_THEME, accent_action is currently set to the same coral color (#cc785c) as accent_primary.\n\nAccording to the design guidelines documented in crates/tui/src/theme_qa_audit.rs (line 77):\n> Every theme must have distinct accent colors.\n\nAdditionally, in all other community themes in this codebase (Catppuccin Mocha, Tokyo Night, Dracula, Gruvbox Dark), accent_action is mapped to the same warm/orange/amber color as mode_plan to provide a distinct, warm accent for interactive actions.\n\nTo maintain visual hierarchy, design consistency, and adhere to the project's theme guidelines, we should use the amber color (#e8a55a) already defined for mode_plan as the accent_action color.

Suggested change

	accent_action: Color::Rgb(0xcc, 0x78, 0x5c), // coral
	accent_action: Color::Rgb(0xe8, 0xa5, 0x5a), // amber

Independent review:

Palette fidelity: Coral #CC785C is close to Anthropic's brand clay #DA7756 (RGB delta ~15) — recognizable but slightly muted. Reasonable choice.

WCAG contrast on surface_bg #181715 (verified):

• text_body 17.0 / text_muted 6.6 / coral 5.5 / teal 7.6 — all pass AA
• text_hint 4.18, text_dim 2.77 (below AA 4.5), error_fg #C64545 3.70 (below AA 4.5 for body text — only OK as accent/large)

Convention break (confirms gemini): accent_primary and accent_action are both #CC785C coral. Every other community theme (Catppuccin peach #FAB387, Tokyo orange #FF9E64, Dracula #FFB86C, Gruvbox #FE8019) uses a distinct warm orange for accent_action. Suggest amber #E8A55A (already used here for mode_plan, contrast 8.5) to keep action-buttons visually distinct from primary surfaces.

Wiring: Clean — ThemeId enum, name/label/description, SELECTABLE_THEMES, normalize_theme_name, theme_remap_active all touched. Builds; 33 palette_audit tests pass.

v0.8.48 (#2256) compatibility: clean merge (Cargo.toml bump to 0.8.47 will be superseded by 2256's 0.8.48) / sibling-PR conflict: all three (#2270 Solarized, #2276 transparent, #2129 Matrix) conflict on palette.rs — same ThemeId enum + match arms + SELECTABLE_THEMES list. Last-merged wins; others need rebase.

Theme cluster coordination — this PR is one of 4 in flight that all add to palette.rs::SELECTABLE_THEMES:

• feat: add Claude theme #2267 Claude theme (this) — recognizable coral #CC785C, full wiring, contrast-conformant for body/muted. One open item: accent_primary and accent_action both set to #CC785C; consider amber #E8A55A for action (gemini-code-assist also flagged).
• feat(theme): add Solarized Light theme #2270 Solarized Light — byte-perfect canonical palette
• feat(tui): add terminal-transparent theme (#2230) #2276 terminal-transparent
• feat(theme): add Matrix films inspired theme and improve theme_picker… #2129 Matrix films

All 4 hard-conflict at the SELECTABLE_THEMES slice and normalize_theme_name arms. Plan: first-merged wins as-is; the other three each get a small rebase. Your palette carries forward unchanged.
