feat: strands review command

[aidandaly24]

Description

Adds a /strands review command that runs a comment-only PR review agent. When a user comments /strands review on a PR, the agent gathers context (diff, linked issue, repo docs), evaluates the change, and posts review comments — without modifying any code.

Two changes:

• New task-reviewer.sop.md SOP that directs the agent through a 4-step review process (gather context → understand code → evaluate → post comments) with explicit forbidden actions (no file modifications, commits, or merges)
• Updated process-inputs.cjs to detect review subcommand and route it to the new reviewer mode with its own SOP

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update
• Other (please describe):

Testing

How have you tested the change?

• I ran npm run test:unit and npm run test:integ
• I ran npm run typecheck
• I ran npm run lint
• If I modified src/assets/, I ran npm run test:update-snapshots and committed the updated snapshots

Integration test failures (10 files / 34 tests) are pre-existing on main — identical results on both branches.
