Closes#2070
Two-layer fix for the bug where executor agents in worktree isolation mode
could leave SUMMARY.md uncommitted, then have it silently destroyed by
`git worktree remove --force` during post-wave cleanup.
Layer 1 — Clarify executor instruction (execute-phase.md):
Added explicit REQUIRED note to the <parallel_execution> block making
clear that SUMMARY.md MUST be committed before the agent returns,
and that the git_commit_metadata step in execute-plan.md handles the
SUMMARY.md-only commit path automatically in worktree mode.
Layer 2 — Orchestrator safety net (execute-phase.md):
Before force-removing each worktree, check for any uncommitted SUMMARY.md
files. If found, commit them on the worktree branch and re-merge into the
main branch before removal. This prevents data loss even when an executor
skips the commit step due to misinterpreting the "do not modify
orchestrator files" instruction.
