fn-22-53k.8 skill: update flow-next-work for completion_review status

Description

Update /flow-next:work skill to handle status=completion_review from selector.

Changes to plugins/flow-next/skills/flow-next-work/:

1. phases.md — Add handling for when flowctl next returns status=completion_review:

   • Detect status after all tasks complete (Ralph.sh line ~943 shows handler pattern: check status == "completion_review")
   • Run /flow-next:epic-review <epic-id> command
   • On SHIP: set completion_review_status=ship, epic can close
   • On NEEDS_WORK: fix loop runs (same as Ralph)

2. SKILL.md — Document completion_review behavior in interactive mode

Pattern reference: fn-22-53k.5 ralph.sh lines 943-954 shows actual implementation (completion_review status handler runs before final else clause). See also: ralph.md lines 297-354 (epic-completion review gate), flowctl.md lines 103-108 (epic set-completion-review-status command), flowctl.md lines 352-360 (next --require-completion-review flag)

NOTE: Without this, interactive /flow-next:work fn-N will fail when selector returns completion_review after all tasks done. Epic-review skill must exist (fn-22-53k.6 responsibility).

Acceptance

• /flow-next:work fn-N handles status=completion_review from selector
• Invokes /flow-next:epic-review when completion review needed
• Fix loop runs until SHIP verdict
• Sets completion_review_status=ship after passing review

Done summary

Updated flow-next-work skill to handle completion_review status. Added Phase 3g in phases.md that checks epic's completion_review_status after all tasks complete, invokes /flow-next:epic-review if needed, and sets status=ship after SHIP verdict.
