Release v0.23.1

[0.23.1] - 2026-03-15

Added

• codeindex claude-md update/status CLI commands: Manage codeindex section in project CLAUDE.md with version tracking.
• Startup version-outdated hint: Every codeindex CLI invocation checks if CLAUDE.md section is outdated and prints a reminder.
• Unified claude_md.py module: Single source of truth for CLAUDE.md injection, replacing fragmented hooks.py + init_wizard.py logic.

Changed

• CLAUDE.md template simplified: 130 lines → 22 lines. Removed hardcoded paths, language support table, and verbose configuration examples.
• Unified marker format: <!-- codeindex:start v{version} --> with backward compatibility for old markers without version.
• init_wizard.py injection: Now delegates to claude_md.py module instead of inline template.

Fixed

• Dead code cleanup: Removed hooks.py post_install_update_guide() (181 lines) that was never wired to pip entry points.
• Dead import fix: cli_config.py referenced non-existent install_hooks from hooks.py, now uses correct install_hook from cli_hooks.py.
