What to build

Extend the /tdd sub-agent invocation to use the full context bundle defined in ADR-0027, replacing the minimal bundle (issue file + PRD only) from the scaffold slice. The bundle adds: all sibling issue files in the feature directory, domain-scoped CONTEXT.md, domain-scoped ADRs, and the last 5 git commits.

Scope is inferred by scanning the PRD for apps/claude-code/<plugin> path references. If found, inject that plugin's docs/adr/ and CONTEXT.md. If not found, inject the root docs/adr/ and root CONTEXT.md.

Acceptance criteria

• Each /tdd invocation receives the full bundle: issue file, PRD, all sibling issue files, scoped CONTEXT.md, scoped ADRs, last 5 git commits
• For a feature whose PRD references paths under apps/claude-code/<plugin>/, the plugin's docs/adr/ and CONTEXT.md are injected
• For a feature whose PRD does not reference any apps/claude-code/<plugin>/ path, the root docs/adr/ and root CONTEXT.md are injected
• Root ADRs are not injected into plugin feature runs
