feat: CLI v2.1.81–v2.1.104 support (#261)

## Summary

Implements support for all Claude Code CLI changes from v2.1.81 through v2.1.104, closing issues #253–#260.

### Changes

- **#253** — New `CwdChanged` hook event: parse and emit `claude:cwd-changed` Tauri event; new `CwdChangedEvent` type
- **#254** — New `FileChanged` hook event: parse and emit `claude:file-changed` Tauri event; new `FileChangedEvent` type
- **#255** — Idle-return prompt: TUI-only feature, not present in `--output-format stream-json` mode — closed as not applicable
- **#256** — New `TaskCreated` and `PermissionDenied` hook events: parse and emit `claude:task-created` / `claude:permission-denied` Tauri events; `PermissionDenied` also triggers `CharacterState::Permission` character animation
- **#257** — Defer permission request: no PreToolUse hook response mechanism in Hikari Desktop — closed as not applicable
- **#258** — `Monitor` tool: added `"Monitor"` to `SEARCH_TOOLS` constant so it maps to `CharacterState::Searching`
- **#259** — `disableSkillShellExecution` setting: wired through `ClaudeStartOptions`, `HikariConfig`, `--settings` JSON, TypeScript interface, and exposed in the Config Sidebar UI
- **#260** — Updated `SUPPORTED_CLI_VERSION` constant from `"2.1.80"` to `"2.1.104"`

All changes pass `check-all.sh` (ESLint → Prettier → svelte-check → Vitest → Clippy → cargo test with llvm-cov).
