feat(02-03): add SSH profile management to ConfigManager

- Add SSH connection profile management methods to ConfigManager
- addSshProfile(): Store connection profiles for quick reconnection
- removeSshProfile(): Remove profiles by ID
- updateSshProfile(): Update existing profiles
- getSshProfiles(): Retrieve all profiles
- setLastActiveContextId(): Persist last active context for app restart
- profiles array and lastActiveContextId field in ssh config section
- Context API already existed from plan 02-02 with all required IPC handlers and preload bridge
