default_risk_profile_for_role decides whether a claw gets file edits, git and
shell by substring-matching its role against a fixed keyword list. On the
planner path that role string is free text the model invented for this
proposal, so a model's choice of wording silently decided tool access: a
proposed "implementation_lead" matches no keyword, lands research_readonly,
and then fails every file edit for a reason invisible from the role name.
TeamMemberInput and the planner's member schema now carry `needs_write`, and
resolve_risk_profile prefers it over the guess. The planner prompt asks for it
per member and says to grant write only to members that produce code or
commits. Absent (older clients, autoprovision, a model that omitted the field)
falls back to the old guess, so nothing changes for callers that don't set it.
