* docs: add repository-wide code review guidelines
Introduces docs/code-review-guidelines.md as the operational review
standard layered on top of AGENTS.md, and adds a Code review guide
section to AGENTS.md that points reviewers at it.
The guide codifies the Product relevance test as a pre-implementation
gate, names the canonical list of forbidden surfaces, lists the
ownership areas in scope, and defines five review lanes: default
code/tests, contract and protocol changes, design-system additions,
skill additions, and craft additions. It also captures the secrets,
runtime data, performance, and maintainability checks that previously
lived only as oral conventions, and aligns the approval bar with the
validation rules in AGENTS.md.
AGENTS.md remains the source of truth when the two disagree; the new
doc is the operational guide on top of it.
* docs: tighten review guidelines for governance docs and bugfix discipline
- Reference scripts/guard.ts as source of truth for guard checks
- Add governance documentation as an explicit in-scope category
- Require reviewers to build a module/caller map before commenting
- Add bugfix-specific reproduction and regression-test checks
- Carve out documentation-only exception in the approval bar
* docs: align review guidelines with repository policy
Keep the review scope aligned with maintained workspace surfaces and preserve AGENTS.md as the authoritative validation bar.
