Phase 0: Parse Arguments

Extract the mode argument (new, update, or status) and resolve the review mode (once, store for all gate spawns this run):

1. If --review [full|lean|solo] was passed → use that
2. Else read production/review-mode.txt → use that value
3. Else → default to lean

See .claude/docs/director-gates.md for the full check pattern.

Phase 1: Gather Context

1. Read the current milestone from production/milestones/.

2. Read the previous sprint (if any) from production/sprints/ to understand velocity and carryover.
