fix: handle Windows drive-letter paths across the codebase (#148)

* Add metrics collection and terminal performance tests

* fix: handle Windows drive-letter paths across the codebase

Windows paths like C:\Users\foo\project were broken in multiple places:
- agent-storage slugified D:\MyProject as D:-MyProject (illegal colon)
- terminal-manager rejected all non-/ paths as relative
- bootstrap parser misparsed drive colons as TCP host:port
- daemon/client connection helpers misclassified Windows paths
- CLI cwd filtering used hardcoded / separators
- checkout-git worktree detection used hardcoded / in path checks
- worktree archive used split("/").pop() instead of path.basename()

All path helpers now normalize separators and handle Windows
drive letters with case-insensitive comparison where needed.
