Mads Hvelplund 962d4459d9 Add configurable token / cost usage limits (#576)
* fix: resolve pre-commit check failures

- Change RuntimeError to TypeError for type validation in report/writer.py
- Update pyupgrade to v3.21.2 for Python 3.14 compatibility

* feat(cli): add --max-budget-usd flag

Raises BudgetExceededError in ReportUsageHooks after each LLM call when
accumulated cost reaches the limit, with clean "stopped" status and
child-agent cancellation in non-interactive mode.

* test: add budget enforcement unit tests

7 tests covering no-budget, under-budget, at-limit, over-limit, error
message content, None report state, and exception hierarchy.
Also adds pytest/pytest-asyncio to dev deps and a mypy override for tests.

* fix(budget): validate positive budget and check the live cost ledger

Two hardening fixes for --max-budget-usd enforcement:

- Reject non-positive budgets. ReportUsageHooks now raises ValueError for
  max_budget_usd <= 0, and the CLI validates the flag via a custom argparse
  type so '--max-budget-usd 0' fails fast with a friendly message instead of
  silently killing the scan on the first model response.
- Read the live cost. The budget check now reads ReportState.get_total_llm_cost()
  (the live ledger) instead of the persisted run-record snapshot, so it stays
  accurate even when a usage save fails after a model call.

* fix(budget): stop the entire scan deterministically when the limit is hit

Previously a BudgetExceededError was handled per-agent: it was swallowed in
interactive mode (the loop kept waiting), a child's error escaped its detached
task as an unretrieved-exception warning, the parent was never released from
wait_for_message, and the stop was logged at ERROR with a traceback as if the
agent had failed.

Replace that with a single scan-wide signal on the coordinator:

- AgentCoordinator.trigger_budget_stop() sets a flag and wakes every parked
  agent; wait_for_message returns as soon as the flag is set.
- The run loops check coordinator.budget_stopped and raise to exit cleanly,
  marking themselves 'stopped'. The root's exception reaches run_strix_scan's
  handler, which cancels descendants and tears the scan down once; child
  exceptions are swallowed in their detached task.
- The budget stop is logged at INFO, not as a failure.

This is deterministic regardless of tree depth or which agent first sees the
limit, fixing the interactive/TUI hang where a deep agent's stop never reached
a parked root. Also re-raises BudgetExceededError explicitly in the stream
handler so it can't be mistaken for the LiteLLM 'after shutdown' race.

* fix(budget): treat a budget stop as a clean stop in the TUI

Add an explicit BudgetExceededError handler in the TUI scan thread so that, if
the error ever reaches it, the budget stop is logged as a graceful stop rather
than surfaced as a red scan error by the broad 'except Exception'. The runner
normally absorbs the error and returns cleanly, so this is defensive depth for
a money-spending feature.

* docs(cli): document --max-budget-usd behavior and limitations

Clarify that the budget is cumulative across all agents, checked after each
model response, that the scan stops cleanly (not as a failure), that the value
must be > 0, and that spend can slightly overshoot due to in-flight calls and
best-effort cost estimation.

* Apply suggestions from code review
