* 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
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* 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

* ci(linter): add renovate/v8-ignore-reason rule
Flag coverage-ignore comments ("v8 ignore") that carry no justification.
Accepted forms: "-- reason" / "--- reason" (recommended) and the legacy
colon form "v8 ignore <kind>[ <count>]: reason", which is already
widespread in the codebase (29 sites). Bare "v8 ignore stop" markers are
exempt because the justification lives on the paired "start" marker. The
"v8 ignore next <N>" count form remains allowed; this rule only requires
a justification.
Registered as "warn" instead of "error": the repo currently has 119
reason-less v8 ignore comments, too many to fix mechanically in one PR,
so existing sites are left untouched and can be fixed incrementally.

* ci(linter): promote renovate/v8-ignore-reason to error
Record the empirical verdict on the contested "v8 ignore next <N>" count
semantics in the rule doc: verified against vitest 4 with
ast-v8-to-istanbul that the count is not honored - the ignore hint always
exempts exactly the next AST node regardless of N. Counts are therefore
inert and stay allowed; the rule keeps requiring only a justification.
Promoting to error so all remaining reason-less coverage-ignore comments
must be fixed; the burndown follows in subsequent commits.

* refactor: add justifications to coverage-ignore comments (batch 1)
Give every reason-less "v8 ignore" comment outside the large platform
index files a site-specific justification explaining why the exempted
branch is untestable or defensive, as now required by the
renovate/v8-ignore-reason rule.
Also guard against a nullish comment.loc in the rule itself; the
merged-in stricter tools typechecking flagged the unguarded access.

* refactor: add justifications to coverage-ignore comments (batch 2)
Cover the five large platform index files (github, bitbucket,
bitbucket-server, codecommit, gitlab) with site-specific reasons on
every "v8 ignore" comment, completing the renovate/v8-ignore-reason
burndown. Two meaningless ignore hints inside commented-out CodeCommit
mergePr code are dropped instead of annotated.
