feat: add multi-repo support (--repos-dir)
Add the ability to work on multiple git repositories at once by specifying a parent directory instead of a single repo.
New components:
- klausagent/discover.py: discover_repos() walks a parent directory to find all git repositories (with configurable max_depth)
- MultiRepoToolsServer: extends the tool server with list_repos and switch_repo tools so the agent can navigate between repositories
- tools:git-multi CLI subcommand: serves all repos under a directory
- --repos-dir flag for chat and telegram subcommands (mutually exclusive with --repo)
Usage: ./run.sh chat --repos-dir /path/to/projects ./run.sh telegram --repos-dir /path/to/projects
The agent gets two new tools:
- list_repos: shows all available repos and which is active
- switch_repo: switch by name, path, or index
All existing single-repo behaviour is preserved (--repo still works).
