ci(cora): add cora review, PR checks, CLA, pre-commit hook, split CI jobs

[ajianaz]

What

• Split CI into separate jobs (check, fmt, clippy, test, build, verify-templates, mutation-testing)
• Add Cora AI Code Review workflow (runs on PR, posts review comment + SARIF)
• Add PR Checks workflow (branch naming, conventional commits, PR template validation)
• Add CLA Check workflow
• Add PR template (.github/PULL_REQUEST_TEMPLATE.md)
• Add pre-commit hook (.githooks/pre-commit) with cora review support

Why

Adopt standard CI patterns from uteke and cora-code repos. Cora review catches code quality issues before merge. PR checks enforce consistent branch naming, conventional commits, and complete PR descriptions. Pre-commit hook runs fmt + clippy + cora locally to catch issues before push.

How

Patterns adopted directly from the reference repos:

Workflow	Source	Adaptation
ci.yml	uteke	Split monolithic job → 7 parallel jobs (faster feedback)
cora-review.yml	cora-code	Same: cora-review-action@v1 + BYOK secrets
pr-checks.yml	cora-code	Branch naming + conventional commits + PR body validation
cla-check.yml	uteke	Fetch signatures from codecoradev/.github
.githooks/pre-commit	uteke	Adaptive language detection (Rust/TS/Go/Python) + cora
PULL_REQUEST_TEMPLATE.md	cora-code	Standard: What/Why/How/Testing/Related Issues/Checklist

CI improvements:

• actions/cache@v4 → Swatinem/rust-cache@v2 (smarter caching)
• RUST_BACKTRACE: 1 + FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true
• Mutation testing: continue-on-error (informational, non-blocking)
• Template names in verify-templates adjusted to cosy's 18 templates

Pre-commit hook usage:

# Install (one-time)
git config core.hooksPath .githooks

# Bypass (ONLY for cora false positives — fmt/clippy MUST pass)
git commit --no-verify

Testing

• All workflow YAML syntactically valid
• Uses standard actions: actions/checkout@v4, Swatinem/rust-cache@v2, dtolnay/rust-toolchain@stable
• GitHub secrets set: CORA_API_KEY, CORA_BASE_URL, CORA_MODEL (repo-level)
• Pre-commit hook tested locally (fmt + clippy clean)
• CI green on this PR (will verify after push)

Checklist

• Branch name follows convention (ci/cora-review-and-pr-checks)
• Branch is from develop
• Commit messages follow Conventional Commits
• No secrets or credentials committed
• One logical change per PR (CI/CD improvements)
