feat(cron): support persistent session targets for cron jobs (#9765)
Add support for `sessionTarget: "current"` and `session:<id>` so cron jobs can
bind to the creating session or a persistent named session instead of only
`main` or ephemeral `isolated` sessions.
Also:
- preserve custom session targets across reloads and restarts
- update gateway validation and normalization for the new target forms
- add cron coverage for current/custom session targets and fallback behavior
- fix merged CI regressions in Discord and diffs tests
- add a changelog entry for the new cron session behavior
