itdove/devaiflow#388: Remove git-cli skill — Claude already knows git

[itdove]

GitHub Issue: #388

Description

Remove the git-cli skill and all references to it across the codebase. Claude Code already has native git knowledge, making a dedicated skill for git commands redundant. This reduces maintenance burden and avoids unnecessary skill overhead for functionality the LLM handles well out of the box.

Changes include:

• Delete devflow/cli_skills/git-cli/SKILL.md
• Remove git-cli from skill discovery, CLI registration, and command utilities
• Update references in other skills (daf-cli, daf-workflow, gh-cli, glab-cli) that previously depended on or mentioned git-cli
• Update documentation (installation, uninstall, skills management, commands reference)
• Update tests to reflect the removed skill

Assisted-by: Claude

Testing

Steps to test

1. Pull down the PR
2. Run python -m pytest tests/test_claude_commands.py tests/test_upgrade_command.py to verify tests pass without git-cli references
3. Run the full test suite to check for regressions
4. Verify git-cli no longer appears in skill listings by running devflow skills list or equivalent
5. Confirm other skills (gh-cli, glab-cli, daf-workflow, daf-cli) still install and render correctly without git-cli references

Scenarios tested

• Test suite passes with git-cli skill and references removed
• Other skills that previously referenced git-cli are updated and functional
• Documentation pages no longer reference the removed skill
