* fix(ruflo-adr): skip .brain when walking for ADRs (#2911)
ruvnet-brain clones ~50 external repos under .brain/repo/clones/,
many carrying their own docs/adr/. Without .brain in SKIP_DIRS,
findAdrs() picked up hundreds of foreign ADRs alongside the
project's own — and since .brain sorts before docs, the project's
ADRs landed dead last in the walk order.

* fix(ruflo-adr): smoke step 22 should not hard-code the test-file count
Was `-eq 3`, breaking every time a new *.test.mjs file is added to
__tests__/ even when the new tests themselves pass. `-ge 3` keeps the
"regression tests exist and run" guarantee without re-breaking on
growth — caught by this PR's own new test file (skip-brain-dir-2911).
