fix: release comms-blocking parks when replies arrive and give every role file authoring tools

Project 3333 forensics: env_engineer sent a blocking question to the CTO,
got a full reply 96s later, and still deadlocked the whole run — the
park half (`_park_for_blocking_comms`) had no wired consumer, so
WAITING_FOR_PEER work items could never be released.

Unpark path (root fix):
- The dispatcher loop now calls `_try_unpark_blocking_comms` each tick
  for parked, non-in-flight tasks; blocking replies land as durable
  inbox files, so the check is read-only until all replies are present.
- `_try_unpark_blocking_comms` accepts orphaned waits (peer_wait
  stripped by the legacy resolver while the work item stayed parked)
  and falls back to the park predicate itself: an empty unresolved
  blocking outbox releases the task, anything pending keeps it parked.
- `resolve_task_peer_wait` no longer touches comms_blocking waits (it
  flipped task.status without the work-item phase and stripped the
  peer_wait evidence); `_resume_peer_checkpoint` re-enters the company
  runtime for comms/orphaned waits and lets the dispatcher converge.

File tools (defaults changed at their declaration sites, honoring the
"empty tools = everything, explicit list = exactly that" contract):
- corporate builtin groups gain file_write/file_edit for coordination,
  QA, and data-acquisition roles.
- all shipped org YAML role tool lists gain the missing
  file_write/file_edit entries.
- coordination turn modes no longer strip file_write/file_edit at
  runtime — in-context content (briefs, matrices) must be persistable
  instead of getting trapped in blocking DM hand-offs.

Also includes the pending office_ui ws_handler change from the working
tree.
