Subject: [PATCH] bootsupport + layout sync: punkboot::utils 0.2.0, pending
 0.2.0 module snapshots

make.tcl modules + make.tcl bootsupport outputs (punkcheck-managed, batched
per src/AGENTS.md): punkboot::utils 0.1.1 -> 0.2.0 (scoped vcs_dirty_warnings)
plus the pending libunknown / mix::commandset::loadedlib / args::moduledoc
tclcore 0.2.0 snapshot updates from the lib.search work, superseded versions
pruned. Layout make.tcl copies picked up the dirty-src provenance gate via the
same bootsupport propagation.

+                    skipped.
+
+                    The scan runs at most once per tm epoch per interp (tracked in the

+                    filesystem and picks up modules added or removed on disk.
+
+                    Returns a stats dict: epoch, roots, dirs, tmfiles, registered - plus

+#        tm_fullscan guard); used by 'dev lib.search' by default
