v0.76.0

Added

• Close or reopen an issue straight from the board (#1051).
  The Closed column is now a drop target on every forge (GitHub, GitLab, Forgejo): drag an open card into it to close the issue, drag a closed card back onto any open lane to reopen it and move it in the same drag. Closing leaves the card's column labels untouched, so it is the forge open/closed state that puts it there, not a label; a reopened card lands at the bottom of its destination lane. The write is forge-first, so a failed close or reopen snaps the card back. Closed issues also sync to a linked project board's Done status where one is available. No new lane is added: the board still reads Backlog, Planned, In Progress, Human Review, Later, Closed.
• Slack DM alert when your Anthropic 7-day rate limit resets early (#1020).
  A new opt-out setting (on by default) fires a loud Slack DM, plus a durable inbox notification, when uzi's usage poller sees your weekly window reopen more than 8 hours before its previously expected reset; it only notifies and does not resume parked runs early.

Changed

• Worker resume durability. A run now carries an owner-anchored checkpoint tip (runs.checkpoint_tip) with a CAS-delete and adoption guard (#1053), and holds worker affinity through a fleet roll with reliable forge checkpoints, so a resumed run keeps its lineage instead of breaking it (#1041).
• Dependency and security bumps. api golang.org/x/crypto CVE fix (#1050) and the Kubernetes client-go monorepo for the controller (#1039).
• Internal refactor sweep (epic #915): large source files split into per-seam files, with no behavior change. forge drivers (#1040), the slacksvc notifier (#1038), the handler route table (#1023) and the schedules and workers handlers (#1056), the settings domain (#1029), the uzicli client (#1027), the api/cmd/uzi CLI (#1028), the controller render.go DinD renderer (#1054), and web page component extraction from RunView and Board (#1018) plus Judge.tsx into pages/judge/ (#1055).

Fixed

• GitHub integer conversion in the forge driver (#1052).
• Default an empty label color on GitLab EnsureLabels (#1035).
• Bound the notification page offset so an out-of-range value returns 400 instead of a bad query (CodeQL alert 28, #1019).
