* fix(insert-phase): update STATE.md next-phase recommendation after inserting a phase
Closes#2502
* fix(insert-phase): update all STATE.md pointers; tighten test scope
Two follow-up fixes from CodeRabbit review of #2509:
1. The update_project_state instruction only said to find "the line" for
the next-phase recommendation. STATE.md can have multiple pointers
(structured current_phase: field AND prose recommendation text).
Updated wording to explicitly require updating all of them in the same
edit.
2. The regression test for the next-phase pointer update scanned the
entire file, so a match anywhere would pass even if update_project_state
itself was missing the instruction. Scoped the assertion to only the
content inside <step name="update_project_state"> to prevent false
positives.
