feat(cron): support per-job reasoning effort

[herbalizer404]

Summary

Adds an optional reasoning_effort override to individual cron jobs, without changing the inherited global default.

• Persists and normalizes a per-job override through the cron model, CLI, and native cronjob tool.
• Propagates the override into scheduled agent runs; missing/cleared values retain global inheritance.
• Supports canonical levels including max; none (and legacy stored false) explicitly disables reasoning.
• Safely falls back to the global configuration for malformed stored values, including unhashable JSON lists/dicts.
• Documents the feature and adds CLI, tool, persistence, and scheduler regression coverage.

Validation

scripts/run_tests.sh tests/cron/test_jobs.py tests/cron/test_scheduler.py tests/cron/test_cron_reasoning_effort.py tests/hermes_cli/test_cron.py tests/hermes_cli/test_cron_parser_builder.py tests/tools/test_cronjob_tools.py
461 passed, 0 failed

Also passed:

• git diff --check origin/main..HEAD
• Windows-footgun check

Compatibility

• No override / cleared override: inherits the existing global reasoning setting.
• none / legacy false: explicit disable.
• Invalid hand-edited stored values: safely inherit instead of crashing the scheduler.

Duplicate of #7382 (the earliest open PR for per-job cron reasoning_effort overrides — same feature, same mechanism at the same cron sites). Sibling entrants #26214 and #30929 are already marked duplicates of #7382; tracking issue #23524 has the demand thread. The max level and malformed-value fallback here are nice touches but don't change that this is the same feature. Canonical remains #7382.

[herbalizer404]

Closing as a duplicate of #7382, which is the canonical upstream proposal for per-job cron reasoning_effort overrides. The local rollout here remains separately tested with explicit handling for max, legacy false, and malformed stored values.
