jif-oai bc005029bd feat: handle goal usage limits in goal extension (#24628) ...

## Why

The extracted goal runtime needs a host-callable path for turns that
stop because the workspace usage limit is reached. In that case, any
in-turn goal progress should be accounted before the goal becomes
terminal, and active goal accounting must be cleared so later
tool-finish or turn-stop handling does not keep charging usage to a
stopped goal.

## What changed

- Adds `GoalRuntimeHandle::usage_limit_active_goal_for_turn`, which
accounts current active-goal progress, marks the active or
budget-limited thread goal as `UsageLimited`, records terminal metrics
when the status changes, clears active goal accounting, and emits the
updated goal event.
- Covers both active and budget-limited goals in
`ext/goal/tests/goal_extension_backend.rs`, including the invariant that
later token/tool events do not add usage after the goal has been
usage-limited.

## Testing

- Added
`usage_limit_active_goal_accounts_progress_and_clears_accounting`.
- Added `usage_limit_budget_limited_goal_accounts_remaining_progress`.
