Release v0.23.2

[0.23.2] - 2026-04-14

Changed

• Hook shebangs: #!/bin/zsh → #!/usr/bin/env bash for cross-platform portability.
• Unified hook install: make install-hooks now delegates to codeindex hooks install --all.
• Post-commit logging: stderr redirected to ~/.codeindex/hooks/post-commit.log instead of /dev/null.
• Debug detection: Replaced ~50 lines of regex-based L2 check with ruff T201/T100 rules.

Added

• hook-common.sh versioned: Added to scripts/hooks/ and auto-copied on codeindex hooks install.
• mypy: Added as dev dependency with baseline config; CI runs informational type check on core modules.
• Coverage gate: CI enforces --cov-fail-under=78 to prevent coverage regression.
• make typecheck: New Makefile target for mypy on core modules.
