Addresses review feedback: moves schedule formatting and state
formatting into dedicated static methods, removes duplicate
in-loop imports, and simplifies _list_jobs() to a clean loop.

_list_jobs() only displayed job name, id, and schedule kind (e.g. "cron"),
omitting the actual timing and run state. The agent couldn't answer
"when does this run?" or "did it run?" even though CronSchedule and
CronJobState had all the data.
Now surfaces:
- Cron expression + timezone for cron jobs
- Human-readable interval for every jobs
- ISO timestamp for one-shot at jobs
- Enabled/disabled status
- Last run time + status (ok/error/skipped) + error message
- Next scheduled run time
Fixes#1496

datetime.fromisoformat(at) raises ValueError for malformed strings,
which propagated uncaught and crashed the tool execution. Now catches
ValueError and returns a user-friendly error message instead.
When a cron job fires, the agent processes the scheduled message and
has access to the cron tool. If the original message resembles a
scheduling instruction (e.g. "remind me in 10 seconds"), the agent
would call cron.add again, creating an infinite feedback loop.
Add a cron-context flag to CronTool that blocks add operations during
cron job execution. The flag is set before process_direct() and cleared
in a finally block to ensure cleanup even on errors.
Fixes#1441
- Remove trailing whitespace and normalize blank lines
- Unify string quotes and line breaks for long lines
- Sort imports alphabetically across modules
