fix(cycle): ambiguous local_path resolves no source — don't stamp an arbitrary pick

resolveSourceForDir used LIMIT 1, so when two sources share a local_path
the dir-keyed freshness stamp (new in this PR) fired for a
nondeterministic one — exactly the 'freshness stamp that lies' the
cycleSourceId comment warns against, and the CI failure in
test/dream.test.ts ('gbrain dream (no --source) leaves all sources
untouched'). Require exactly one match; ambiguous or no match falls back
to the pre-v0.18 behavior (undefined), same as before this PR for the
no-match case.
