chore(memory): re-apply consolidation deletions + lift additive-only constraint

The 39 files I deleted in d676a9a got resurrected by sync-memory.sh on
GURU-5070 (0daa795) because the script is additive-only. Re-deleted them
(49 files this time -- some additional drift between machines).

Also added feedback_memory_sync_destructive_ok.md capturing the policy
shift: with everyone onboarded, the memory tooling no longer needs
additive-only safety. memory-dream may apply proposed merges/deletions
and sync-memory.sh should propagate repo-side deletions back to profile
stores. Script updates to honor that are still pending -- without them,
this round of cleanup is also vulnerable to resurrection.

Self-check: 0 WARN, 1 FAIL remaining (autotask command -- manifest issue,
not fixable on this machine; needs Mike to either un-localize /autotask
or move it to capability-gated in baseline/manifest.json).
