feat: add clickable example commands to welcome screen (#23)

* feat: add clickable example commands to welcome screen

Add 4 example commands to the welcome splash screen to make the client
more friendly on cold start and to new users:
- nip 29: View relay-based groups spec
- profile verbiricha@habla.news: Explore a Nostr profile
- req -k 1 -l 20: Query recent notes
- nips: Browse all NIPs

Commands are clickable and execute directly, opening the appropriate
window without requiring users to type or use the command palette.

Changes:
- Update GrimoireWelcome component with EXAMPLE_COMMANDS constant
- Add onExecuteCommand prop to handle direct command execution
- Update WorkspaceView to pass handleExecuteCommand callback
- Use parseAndExecuteCommand from command-parser for execution

* fix: lint
