feat: clone GitHub repo into a workspace (#1331)

* feat: clone GitHub repo into a workspace

Add an end-to-end "clone a GitHub repo and register it as a Paseo
workspace" flow: a new workspace.github.clone RPC, daemon handler,
client method, CLI `paseo clone` command, and a GitHub-repo mode in
the project picker modal. Gated behind the workspaceGithubClone
server capability flag.

- protocol: workspace.github.clone request/response schemas + feature flag
- server: handleWorkspaceGithubCloneRequest, normalizeCloneRepository
- client: DaemonClient.cloneGithubWorkspace
- cli: `paseo clone <repo> --dir <path> [--protocol https|ssh]`
- app: GitHub-repo mode, clone-protocol picker, error surfacing

Review fixes:
- CLI clone now checks the workspaceGithubClone capability and fails
  fast with a clear "update the host" error instead of hanging for the
  full request timeout against an older daemon.
- Replace the duplicated client-side URL-detection regex (app + CLI)
  with a shared isCompleteGitRemote() in @getpaseo/protocol/git-remote,
  backed by parseGitRemoteLocation so clients classify remotes
  identically to the daemon (fixes confusing errors for git://, ftp://,
  file:// inputs).
- Add git-remote.test.ts covering the shared classifier.

* Fix GitHub clone failure handling
