feat(kanban): add scheduled status for delayed follow-ups

Salvages #24533 by @roycepersonalassistant. Adds a first-class
'scheduled' Kanban status for time-delay follow-ups that aren't
waiting on human input.

- hermes kanban schedule <task_id> [reason] CLI command
- Dashboard/API transitions to/from Scheduled
- unblock_task() now releases both 'blocked' AND 'scheduled' tasks
  (re-checking parent dependencies before moving to ready/todo)
- i18n + docs updates

Resolved conflicts: kept HEAD's failure-counter reset on unblock
alongside the PR's scheduled state, kept HEAD's 'running' direct-set
rejection, combined both bulk-status branches. Dropped the dist/
bundle changes (months-stale; would need rebuild from source).
