Adds consistent manual Workboard movement across CLI, slash commands, and agent tools while preserving operator authority and agent claim isolation.

Centralized managed worktrees under <state-dir>/worktrees/<repo-fingerprint>/<name>
with branch-per-task (openclaw/<name>), .worktreeinclude provisioning, an optional
.openclaw/worktree-setup.sh repo hook, and a SQLite registry in the shared state DB.
Removal always snapshots the tree (untracked included, gitignored excluded) to
refs/openclaw/snapshots/<id>; restore rebuilds the branch at the original commit with
the snapshot content as uncommitted state. Lossless run-end cleanup, 7-day idle GC for
run-owned worktrees (manual exempt), orphan reconciliation, 30-day snapshot retention.
Surfaces: worktrees.* gateway RPC (operator.admin mutations), openclaw worktrees CLI,
Control UI page, plugin-SDK facade + Workboard kind:"worktree" materialization.
E2E-verified on Testbox: full create->work->remove->restore->gc lifecycle.
