feat: CLI v2.1.68–v2.1.74 compatibility updates (#221)

## Summary

This PR brings Hikari Desktop up to full compatibility with Claude Code CLI versions v2.1.68 through v2.1.74, implementing all changelog items audited in issues #200–#218.

## Changes

### Bug Fixes
- Remove deprecated Claude Opus 4.0 and 4.1 models from the model selector
- Auto-migrate users pinned to deprecated models to Opus 4.6

### New Features
- Add cron tool support (`CronCreate`, `CronDelete`, `CronList`) with character state mapping and `CLAUDE_CODE_DISABLE_CRON` settings toggle
- Handle `EnterWorktree` and `ExitWorktree` tools in character state mapping and tool display
- Add CLI update check with npm registry indicator in the version bar
- Add `agent_type` field and support the Agent tool rename from CLI v2.1.69
- Consume `worktree` field from status line hook events
- Display per-agent model override in the agent monitor tree
- Expose Claude Code CLI built-in slash commands (`/simplify`, `/loop`, `/batch`, `/memory`, `/context`) in the command menu with CLI badges
- Add `includeGitInstructions` toggle in settings
- Add `ENABLE_CLAUDEAI_MCP_SERVERS` opt-out setting
- Linkify MCP binary file paths (PDFs, audio, Office docs) in markdown output
- Add auto-memory panel, `/memory` slash command shortcut, and unified toast notification system
- Toast notifications for `WorktreeCreate` and `WorktreeRemove` hook events
- Sort session resume list by most recent activity, with most recent user message as preview
- Convert WSL Linux paths to Windows UNC paths when opening binary files via `open_binary_file` command
- Expose `autoMemoryDirectory` setting in ConfigSidebar (Agent Settings section)
- Add `/context` as a CLI built-in in the slash command menu
- Expose `modelOverrides` setting as a JSON textarea in ConfigSidebar (for AWS Bedrock, Google Vertex, etc.)

> **Note:** The CLI update check commit does not have a corresponding issue — it was a bonus addition during the audit sprint.
