refactor: remove CLI dead code

Remove unused daemon installation/uninstallation logic and unnecessary re-exports:
- Delete cli/src/daemon/mac/ directory (macOS LaunchDaemon install/uninstall not used)
- Delete cli/src/daemon/install.ts and uninstall.ts wrappers
- Remove daemon install/uninstall subcommands from cli/src/commands/daemon.ts
- Delete cli/src/api/encryption.ts (misleading name, just base64 encoding)
- Inline base64 encoding directly in cli/src/persistence.ts
- Delete cli/src/modules/common/gitHandlers.ts (unnecessary re-export)
- Update cli/src/modules/common/registerCommonHandlers.ts to import directly from handlers/git

Part of refactoring plan item #1 "删除 CLI 死代码".
