GrzegorzandClaude Opus 5.5 afecd44ddf fix(approvals): let "approve once" run ungranted bash/python, close skill-test streams (#6635) (#6683)
ToolApprovalStore.create() sealed a process identity only from the request
authority's launch scopes, which exist only for granted bash/python. For an
ungranted call the sealing failed silently, so the approval was created
without a process identity and the executor always refused it ("Approved
action has no sealed process/job identity"). When the authority is not
inherited and has no launch scope for the backend, seal one in the
request's single workspace root at approval time, as filesystem approvals
already do. Inherited authorities still cannot widen.

The skill test run and audit arm left their `async for` over
stream_agent_loop early when an approval was needed, without closing the
generator. asyncio closed it later from another task, so its ContextVar
resets raised "Token ... was created in a different Context". Close the
stream with aclosing, like the scheduler and teacher escalation do.

"""An exact approval must be able to run a bash/python call the request did not grant (#6635).
`ToolApprovalStore.create()` sealed the process identity only from the request
authority's launch scopes, and those exist only for granted bash/python
backends. For an ungranted call the sealing failed silently, so the approval
card was created with no process identity and the executor refused it:
"Approved action has no sealed process/job identity".
