feat(kb): roam-sync script + timer units, old roam path repointed

Phase 0 of the agent KB spec: the org-roam KB now lives at ~/org/roam as a git repo on cjennings.net. roam-sync.sh (bats-tested: commit, rebase, push, conflict-abort) runs from a 15-minute systemd user timer; canonical unit files live in scripts/systemd/. Live references to the old ~/sync/org/roam path (the task-list pointer, the journal workflow, the notes template) repoint to ~/org/roam, and a transition symlink at the old location covers stragglers.

+# roam-sync.sh — git auto-sync for the org-roam knowledge base (spec D8).
+#
+# Commit any local changes, rebase onto the remote, push. Run by the
+# roam-sync systemd user timer (scripts/systemd/) every 15 minutes so
+# Craig's hand edits travel without a manual git step. Agents don't need
+# this — they pull/commit/push inline per claude-rules/knowledge-base.md.
+#
+# On a rebase conflict: abort the rebase (never leave the repo mid-rebase
+# for a timer to mangle), keep the local commit, exit 1 so the failure is
+# visible in `systemctl --user status roam-sync`.
+#
+# Usage: roam-sync.sh [repo-path]   (default ~/org/roam)
