Matrix CWD doesn't expand tilde (~) paths

[c-h-]

Bug

When launching via agentctl launch --matrix, the cwd field in the matrix YAML doesn't expand ~ to the home directory. Instead it's treated as a relative path from the current working directory:

Parallel launch failed: Not a git repository: /Users/ms/.openclaw/workspaces/kindo/~/code/mono

Repro

# matrix.yaml
cwd: ~/code/mono  # <-- not expanded

agentctl launch --matrix matrix.yaml
# Error: Not a git repository: <cwd>/~/code/mono

Expected

~/code/mono should resolve to /Users/<user>/code/mono, same as shell expansion.

Workaround

Use absolute paths in matrix YAML.
