b21463aab6 fix(evals): harden terminalbench-native harness against tmux death and setup hangs (#536)
Two failure classes hit by a downstream team:

1) tmux/task-env death (TerminalBenchTaskEnv.__enter__, terminalbench_env.py):
   create_session ran inside the spin_up_terminal generator-CM with no
   exception safety — a tmux failure leaked the docker compose project
   (down deferred to GC, never if the env was retained) and surfaced as an
   opaque mid-run death. Now: exception-safe __enter__ with an idempotent
   _teardown(), a tmux/asciinema preflight in the container BEFORE the
   agent loop (TaskEnvironmentError naming the task image + remedy), and
   fail-that-task-cleanly semantics — the failure is recorded as a harness
   error (QueryTrace.error_kind="harness_error"), the container is downed,
   and the run continues.

2) OpenHands in-container SETUP hang misattributed as a model result:
   harness.run() had no bound (terminal-bench runs installed-agent setup
   with max_timeout_sec=inf inside the per-trial agent budget), and the
   summary conversion read the nonexistent results.trial_results attr and
   hardcoded errors=0, folding zero-model-request trials into resolve-rate
   as model misses. Now: global_agent_timeout_sec / global_timeout_multiplier
   are threaded config -> backend -> Harness kwargs (default 1800 s bound on
   SETUP+RUN; configurable per [run]/[[benchmarks]] TOML), and
   summarize_benchmark_results() classifies harness/infra failures out of
   the accuracy denominator keyed on token usage (zero/missing tokens +
   unresolved = the agent never contacted the model), NOT failure_mode —
   terminal-bench 0.2.18 leaves failure_mode UNSET on success AND on
   genuine misses, so a failure_mode-based check would misflag every real
   model miss. Genuine misses (tokens>0, is_resolved=false) stay in the
   denominator.

QueryTrace gains error/error_kind (wired through to_dict/from_dict so the
fields actually reach traces.jsonl; backward-compatible loads), the
AgenticRunner flags zero-model-contact traces and TaskEnvironmentError as
harness errors, and export/summary/console output exclude harness errors
from resolve-rate while reporting them loudly.

terminal-bench stays an undeclared dep on purpose: it requires Python
>=3.12 while this project supports >=3.10,<3.14, so an unmarked extra
would break uv lock. pyproject/uv.lock untouched.
