* ci(linter): add renovate/require-regex-util rule
Adds a custom oxlint rule that flags raw RegExp usage in lib/
production code: any `new RegExp(...)` call and any regex literal
that is not the direct first argument of `regEx(...)`. The regEx()
helper from lib/util/regex.ts uses the RE2 engine for ReDoS-safe
matching and caches compiled patterns. lib/util/regex.ts itself is
exempt.
The rule is disabled for **/*.spec.ts, test/**, and tools/** via
config overrides, because vitest APIs such as expect.stringMatching
need bare RegExp instances (a past commit reverted regEx() there).
Severity is set to "warn" instead of "error": the repo currently has
197 pre-existing violations (above the agreed mechanical-fix
threshold of 80), and a number of them are deliberately
RE2-incompatible patterns (lookahead/lookbehind/named backreferences,
see TODO #12872/#12875 markers in e.g. lib/modules/versioning/rez/
pattern.ts and lib/modules/manager/dockerfile/extract.ts) that need
per-site judgment before they can be wrapped in regEx() or suppressed
with a justified disable comment. No violation fixes are included in
this commit.

* refactor: use regEx() for regex literals and RegExp construction in lib
Burn down all renovate/require-regex-util violations (197):
- wrap RE2-compatible regex literals and RegExp constructions in regEx()
- rewrite lookaround patterns where behavior is provably preserved:
goproxy separator split, sbt-package link extraction, leiningen
comment stripping and keyword search, npm GitHub owner validation
(unit-count bound replaced by an explicit length check)
- keep native RegExp with disable comments where RE2 cannot be used:
moo / good-enough-parser lexer patterns (moo rejects RE2 instances),
MigrationsService propertyName (matched via isRegExp, which RE2
instances fail), rez named backreferences and lookaheads, GitHub
markdown link negative lookbehind, emoji astral-plane matching
- drop stale TODO #12875 comments for patterns current re2 handles

* refactor: reduce require-regex-util disable comments
Rewrite the github massage-markdown-links URL regex to capture an
optional `api.` prefix in a named group (skipped in code) instead of
relying on a negative lookbehind, so both the base and global variants
can use regEx()/RE2 and their two disable comments are removed. Add
spec cases for api-prefixed URLs that match the URL shape.
Consolidate the four related line disables in rez/pattern.ts (bound and
range patterns emulating Python conditional patterns via named
backreferences and lookaheads, which RE2 cannot express) into a single
block disable/enable pair, matching the treatment of the lexer files.
Disable comment count drops from 13 to 8.

* refactor(datasource/sbt-package): use named capture group in link regex

* refactor(manager/cake): restore original multiLineComment regex spelling
The [^] -> [\\s\\S] rewrite was only needed for an RE2 wrap that was
later reverted; keep the diff minimal.

* fix(datasource/go): skip empty GOPROXY segments
The switch from a lookahead split to a capture-group split (needed because
RE2 has no lookahead support) changed how empty GOPROXY segments parse:
`a|,b` yielded `{ url: ',', fallback: '|' }` before and
`{ url: '', fallback: ',' }` after. The comma fallback only continues on
404/410, so a failing proxy ahead of an empty segment silently stopped the
lookup instead of falling through to the remaining proxies.
Empty segments carry no url to query, so drop them.
* refactor(datasource/go): use isTruthy for empty segment filter
* fix(datasource/go): filter empty segments before mapping
Filtering after the map broke the contextual typing from the
GoproxyItem[] annotation, widening fallback to string.
* refactor(platform/github): use regEx() for merge queue query stripping
