feat: add Git Commit Assistant workflow for quality checks and message generation

[pontemonti]

This pull request introduces a new agent definition for commit assistance in the .claude/agents/commit.md file. The agent guides users through a structured workflow for committing staged changes, ensuring code quality by running linting and tests, and generating conventional commit messages. The workflow includes clear user prompts and error handling to improve commit reliability and message quality.

Commit Workflow Agent Addition:

• Added a detailed agent specification in .claude/agents/commit.md for a Git Commit Assistant that automates and quality-controls the commit process, including activation triggers and stepwise phases.

Quality Assurance Steps:

• Defined sequential phases: pre-commit validation, linting (with auto-fix options and user prompts), running tests (with hard stop on failures), commit message generation, and commit execution.

Commit Message Standards:

• Outlined conventional commit message types, scope guidelines, and message quality requirements, ensuring consistency and clarity in commit history.

User Interaction and Error Handling:

• Provided example session and detailed error handling instructions for common scenarios (no staged changes, lint/test failures, git errors), improving user experience and reliability.
