Integrate native Rime and stabilize input, output, and rendering

- Add optional modifier-only Super binding whose tap is cancelled by
  other input, focus changes, grabs, locks, and session teardown.
- Ship the native ferese-rime user service, Rime defaults, installer
  inventory, package dependencies, session environment, and docs.
- Vendor Smithay 8a27023 with the SHM texture-cache format fix and add
  GPU regressions for format changes and resize snapshots.
- Release reused CRTC owners before staging output modes, then restore
  changed outputs before former owners when a transaction fails.
- Wait for resize-capture GPU completion, expand filtered surface
  damage, and preserve IME popup origin under fractional scaling.
- Mark weekends like holidays in both calendar layouts.

 A binding replaces the same normalized chord/match mode. Duplicate bindings are
 invalid. A disabled binding must omit `action` and `argument`.
 
+A modifier-only `Super` binding is optional:
+
+```kdl
+binding "Super" action="toggle-launcher"
+```
+
+Either Super key triggers this action when released after an isolated press.
+The original press and release still reach the focused application. Other keys,
+both Super keys together, pointer movement, clicks, scrolling, gestures and touch
+cancel the tap; a mouse button already held also prevents it. Existing Super
+chords, including Super+Space, keep their actions. Key repeat does not retrigger
+the tap. Locking, shortcut inhibition, client keyboard grabs, focus changes and
+device/session teardown cancel pending taps. Native input-method grabs remain
+compatible. `Logo` and `Mod4` name the same tap, so they cannot be configured as
+separate bindings. Physical matching is not supported for this trigger.
+
+Use `binding "Super" disabled=#true` to remove a configured tap. Without a tap
+binding, Super keeps its existing modifier behavior.

+不读取、迁移或覆盖 IBus/Fcitx 的个人词库，也保留该目录内已有的用户定制。
+Rime 由会话固定版本的 systemd 用户临时服务运行，异常后重启并启用十秒输入循环 watchdog；
+服务名称由合成器控制套接字稳定生成，Shell 硬崩溃恢复时仅替换该会话的旧输入法实例。
