Schedule-it

Changed

• Plugin Store metadata: developer URL, changelog URL, authors and an icon.
• Licence file renamed to LICENSE.txt (MIT).

• Renamed from webdna/scheduler (handle scheduler) to webdna/schedule-it (handle schedule-it). The Plugin Store already lists Verbb's Scheduler under the handle scheduler, and Craft's update check matches plugins by handle, so every install was offered that plugin's updates in the control panel.
• The schedule moves to config/schedule-it.php, the commands to schedule-it/run and schedule-it/list, the namespace to webdna\\scheduleit, and the default log file to storage/logs/schedule-it.log. The plugin keeps nothing in the database, so moving is uninstall the old, install the new — see the README.
• schedule-it/run and schedule-it/list refuse to start while the schedule is still in config/scheduler.php and config/schedule-it.php does not exist, rather than running nothing.
• craft scheduler/run fails with a pointer to schedule-it/run once the old plugin is gone.

• craft schedule/run now fails with a pointer to scheduler/run. The underlying library registers schedule/run on every console app through Yii's extension bootstrap, where it ran an empty schedule and exited 0 — so a cron entry left on the old command reported success every minute while running nothing. A schedule command a project configured itself is left alone.

• Initial release: the schedule in config/scheduler.php, run by one scheduler/run cron entry.
• Jobs can be written in words — Job::command('gc/run')->dailyAt('03:00'), ->weekdays()->at('08:30') — or as cron expressions, side by side.
• Jobs default to UTC, a cross-server lock, stdout and stderr in the log file, and replay of that output to the runner's stdout.
• scheduler/run reports each job's exit code and exits non-zero if any failed, and refuses to start on a file or null mutex unless singleServer is set.
• scheduler/list shows every job and its next due time.
• A misspelt key, bad expression or unknown timezone in the schedule is an error, never a job that silently does not run.
