Code Polish

Resolve scope once, make only high-confidence simplifications, fix evidenced defects by risk, and verify the final state.

Modes

• --simplify: simplify only.
• --review: review and fix only.
• Neither or both: simplify, then review the simplified result.
• --with-profile <name> / --skip-profile <name>: add or suppress review profiles; skip wins.
