Add optional modifier-key and active-schema hints to the existing input status panel. Both default off and reuse candidate fonts and themes. The schema name appears on non-ASCII focus, disappears on typing or timeout, and replaces the Chinese-mode label when name hints are enabled.

patch:
  "modifier_hint/show": true
  "focus_hint/show": true
  "focus_hint/duration": 2

The implementation is event-driven. Modifier state follows IMK key/flags events; focus expiry uses one cancellable, non-repeating timer. Existing Rime status reads supply mode changes. No input-source, modifier or caret polling remains.

Options are cached when settings load. With both hints off, the runtime and presenter are absent: no hint dependencies, state/caret queries, timer scheduling or hint rendering; only cached optional checks remain. The original status formatting, rendering and lifecycle are retained for this path. Disabling cancels existing work and clears hints. Closing the menu-bar icon also skips its label reads and main-queue dispatch.

Validation:

• 10,000 simulated disabled event sequences: 0 dependency constructions, 0 provider reads, 0 timer schedules, 0 renders.
• Enabled-mode tests cover single-shot expiry, custom duration, typing/mode/blur cancellation, and modifier-only operation without a focus read or timer.
• Local Swift type checking passed; disabled-path status formatting/rendering were compared with upstream source.
• Full fork CI passed: tests, SwiftLint, universal build, packaging and Periphery. The application sources are unchanged from this run; its validation workflow is excluded from this PR.
• Manual UI acceptance of the optimized revision is pending.

README documents setup and event behavior. Hints require client-provided activation and valid caret geometry; missed modifier-release events are resynchronized by the next keyboard/focus event. Caps Lock and Fn are excluded.

很酷很有創意。可是有無實用價值？

用性能換小玩具，推給用戶須謹慎。

因为我是vim用户, 经常受到中英文输入状态的困扰, 没有输入状态栏会影响使用.
如果不作为功能添加, 是否可以改成增加一种hook 扩展机制, 自行定制这块的行为?

看輸入狀態可以試試這項新功能：

後端功能 librime 插件可以提供擴展；前端代碼由 @LEOYoon-Tsaw 重寫後，我不熟悉；如何設計前端功能擴展點，還沒有清晰思路。

目前的代碼改動看上去還不能清晰地分解開，提取模塊，能否關閉乾淨都不敢保證。所以不敢輕易上馬。
