New guard in touchfiles.test.ts: every non-glob dep path must exist, and every
glob's anchor directory must exist. This is the axis the 181-key two-map sync
discipline never covered — an entry can point at a long-deleted file and
diff-based selection then silently never triggers those tests (the sidebar
trio sat rotted for 48 versions).
First run immediately caught a fourth rotted entry: 'spec authored quality'
referenced test/fixtures/spec/** (directory does not exist) and selected for a
judge test that exists nowhere in the repo. Removed.
