test: mock retry backoff and compression sleeps in slow tests

Cuts ~65s off shard 3's local runtime (108s \u2192 48s) by neutralizing
real wall-clock waits in backoff/compression/retry paths. Tests assert
behavior (retry count, final result, error handling), never timing.

Changes:
- tests/run_agent/conftest.py (NEW): autouse fixture mocks
  run_agent.jittered_backoff to 0.0 for all tests in the directory.
  Collapses the `while time.time() < sleep_end` busy-loop to a no-op.
  Does NOT mock time.sleep globally (breaks threading tests).
- test_anthropic_error_handling.py: per-file fixture mocks time.sleep
  and asyncio.sleep for this test's retry paths (6 tests \u00d7 10s \u2192 ~2s each).
- test_413_compression.py: mocks time.sleep for the 2s compression retry
  pauses (9 tests \u00d7 2s \u2192 millisecond range).
- test_run_agent_codex_responses.py: mocks time.sleep for Codex retry
  path (6.8s \u2192 0.24s on the empty-output retry test).
- test_fallback_model.py: mocks time.sleep for transport-recovery path.
- test_retaindb_plugin.py: caps retaindb module's time.sleep to 0.05s
  so background writer-thread sleeps don't block tests. Replaces
  arbitrary time.sleep(N) waits with polling loops.

Validation:
- tests/run_agent/ + tests/plugins/test_retaindb_plugin.py: 827 passed,
  0 failed, 22.9s (was ~75s before).
- Matrix shard 3 local: 3098 passed, 48.2s (was 108s).
- No test's timing-assertion contract is changed (tests still verify
  retry happens, just don't wait 5s for it).
