fix: replace colons in command filenames for Windows compatibility

[jamiechicago312]

Fixes #230

Problem

Colons in filenames (e.g., automation:create.md) break git sync on Windows.

Solution

1. Replace : with - in scripts/sync_extensions.py
2. Rename 8 existing colon-named files

Nice fix. Replacing : with - in generated command filenames keeps the change small and easy to maintain, while the command trigger itself still stays unchanged. I pushed one follow-up commit (84a2f6c) that adds a focused regression test so this Windows-compatibility behavior stays covered going forward.

Validation I ran:

• .venv/bin/python -m pytest -q tests/test_sync_extensions.py
• .venv/bin/python scripts/sync_extensions.py --check

@malhotra5 I think there are other examples where colons are used in SKILLS related to pre-built automations, such as github-repo-monitor. I think we need to make sure this is fixed across the pre-built extensions.

LGTM

Also just to note, in the latest versions of agent canvas we no longer git clone the extensions repo. Rather we bundle the npm package for the extensions repo directly into the agent canvas. Nevertheless this seems like a good fix to get in
