* docs(#3182): ADR-3180 — planning semantic model single owner
Phase 0 design lock for epic #3180. Names one canonical owner per
semantic derivation, specifies the frozen-enum scope contract that
distinguishes a genuinely-empty computation from a truncated or
unscoped one, and locks the drift-guard contract.
Ships no production code. Phases 1-5 execute against this ADR.

* test(#3182): prune real issue 3182 from phantom-ref guard, fix empty-list regex
The guard's own header documents that its list rots: entries are phantom
only until the repo's shared issue/PR counter reaches them, and once the
counter passes an entry it must be deleted. Creating the Phase-0 sub-issue
advanced the counter past 3182, so the guard began rejecting a legitimate
citation of a real issue - the failure its header already records happening
twice, with PRs 2551 and 2361.
3182 was the last entry, and removing it exposed a latent bug: the regex
builder interpolated the list unconditionally, so an empty list yields
(?:#(?:)\b)|(?:issues/(?:)\b), whose empty alternation matches every issue
reference in the repo. Following the file's own maintenance instruction
would have turned a green guard into one failing on nearly every file.
buildRefRe() now returns null for an empty list and is exported, with
boundary coverage at 0/1/2 entries plus word-boundary and bare-digit
negative cases.
