Overview

Bounded, marker-based reconcile sweep replacing the destructive per-entry rm -rf prune.

Lifecycle (driven by TemplateDirectoryRenderer):

1. Construct (touches a marker file; its mtime is the cutoff) BEFORE any rendering/forking.
2. Render writes files (mtime > marker); PlaceholderExpander copies preserve a just-rendered
 source mtime (also > marker).
3. After all rendering, `sweep!` each scope root: delete files strictly older than the marker
 (leftovers from deleted/renamed entries), then remove now-empty directories.

spp/ subtrees are fenced out of the base sweep; per the ticket, deleted-SPP cleanup is a manual git rm, never an automatic sweep.
