feat: replace pre-commit with husky

[ctrl-alt-d]

Replace pre-commit with husky + lint-staged + commitlint

Why

pre-commit requires Python, which is an unnecessary dependency for a pure Node.js/Astro project. husky is the standard for git hooks in the JS ecosystem and integrates natively with pnpm.

Changes

• Removed .pre-commit-config.yaml
• Added husky, lint-staged, @commitlint/cli, @commitlint/config-conventional
• .husky/pre-commit: runs astro check + prettier --check (via lint-staged, only on staged files)
• .husky/commit-msg: validates conventional commits via commitlint
• Updated README: removed Python/pre-commit from requirements

Same checks, same behavior

Before (pre-commit)	After (husky)
astro check on commit	astro check on commit
prettier --check on commit	prettier --check on staged files
conventional-pre-commit	@commitlint/config-conventional

After merging

• Contributors only need pnpm install — hooks are configured automatically via the prepare script.
• Python and the env/ virtualenv are no longer needed. Each contributor can delete their local env/ directory.
