Add logger coverage lint and Claude Code PostToolUse hook

[hiroshinishio]

Summary

• Add scripts/lint/check_logger_coverage.py (AST-based) enforcing CLAUDE.md logger rules: every return/continue/break in a function needs a preceding logger.xxx(...) call, and every if/elif/else branch body starts with one.
• Wire the check into scripts/git/pre_commit_hook.sh so staged .py files are blocked at commit time, skipping tests/scripts/schemas/venvs.
• Add a Claude Code PostToolUse hook (Edit|Write|MultiEdit) at .claude/hooks/check-logger-coverage.sh that runs the same check and returns decision:block with violation details so Claude fixes before continuing, not in a later commit.

Social Media Post (GitAuto)

Logger coverage is now enforced automatically

• New lint script checks that every return/continue/break has a preceding logger call and every if/elif/else branch starts with one
• Wired into pre-commit so violations block the commit with the exact lines to fix
• Claude Code now gets the same check as a PostToolUse hook, blocking the agent on any edited file until logs are added

Social Media Post (Wes)

Kept writing "add a logger before that return" in reviews. Moved it into a pre-commit script and a Claude Code PostToolUse hook that blocks the edit right when it happens, with the line numbers in the block reason. Same rule, one place, no more nagging.
