Erich Blume 5894d134a8 Add pre-commit hooks for code quality and fix all lint violations
Introduces pre-commit framework with hooks for:
- General file hygiene (trailing whitespace, EOF, large files)
- Secret detection (TruffleHog)
- YAML linting (yamllint)
- Ansible linting (ansible-lint)
- Python linting/formatting (ruff)
- Shell script analysis (shellcheck, shfmt)
- TOML formatting (taplo)
- JSON formatting (prettier)

Fixes 91+ ansible-lint violations:
- Renamed variables to use role prefixes (e.g., brew_start -> alloy_brew_start)
- Capitalized handler names per convention
- Added changed_when to command tasks
- Fixed template usage in task names

Fixes shellcheck warnings:
- Removed unused variables
- Fixed SC2155 (declare and assign separately)
