feat(cron): Profile-scoped cron with parallel execution (#334)

Rescued from blocked PR #307. Clean reimplementation on current main.

## What
- Jobs accept a `profile` field — when set, the scheduler resolves that
  profile's config.yaml + .env and sets HERMES_ACTIVE_PROFILE before running
- Parallel execution: tick() now uses ThreadPoolExecutor (default 4 workers,
  configurable via HERMES_CRON_PARALLEL_WORKERS env var)
- Profile isolation: each job loads only its profile's config/env, preventing
  cross-contamination between concurrent jobs

## Changes
- cron/jobs.py: `profile` field on create_job(), stored on job dict
- cron/scheduler.py:
  - _resolve_profile_home() — resolves profile name → HERMES_HOME dir
  - _load_profile_env() — loads profile .env without touching os.environ
  - _load_profile_config() — loads profile config.yaml
  - run_job() — profile-aware config/env loading + HERMES_ACTIVE_PROFILE
  - tick() — parallel execution via ThreadPoolExecutor
  - Added missing ModelContextError + CRON_MIN_CONTEXT_TOKENS
- tools/cronjob_tools.py: `profile` param on create/update, schema, format
- hermes_cli/cron.py: `--profile` on create/edit, display in list
- tests/cron/test_profile_cron.py: 15 tests covering profile field CRUD,
  resolution, isolation, parallel execution, and tool integration

## Testing
106 tests pass (52 existing cron jobs + 15 new profile tests + 39 tool tests).
