* 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

* refactor(oxlint): enable func-style
Enable the built-in func-style rule as ["warn", "declaration"] so that
named functions are written as function declarations instead of arrow or
function expressions assigned to variables, matching the convention in
docs/development/best-practices.md (Functions section). Inline arrow
callbacks are unaffected; prefer-arrow-callback continues to cover the
callback direction.
Severity is "warn" instead of "error" as a fallback: a repo-wide run
found 196 pre-existing violations (70 in spec files, 126 in production
code), exceeding the 80-violation fix threshold for this change, so no
violations were fixed here. Follow-up work can convert the offenders
(largest clusters: lib/modules/versioning/ruby, lib/util/cache/package,
lib/modules/versioning/maven, lib/modules/versioning/gradle) and then
raise the rule to "error". Note oxlint 1.72 also supports an
allowTypeAnnotation option if typed consts should remain arrows.

* ci(linter): enforce func-style at error
* refactor(func-style): convert const-arrow functions to declarations in with-cache spec and ruby versioning
* refactor(func-style): convert const-arrow functions to declarations in maven/gradle modules
* refactor(func-style): convert const-arrow functions to declarations in remaining versioning modules
* refactor(func-style): convert const-arrow functions to declarations in platform modules
Discriminated-union closures (ensureCommentRemoval byTopic/byContent
helpers in github, gitlab, bitbucket, bitbucket-server) needed the
narrowed field passed explicitly as a parameter, since function
declarations are hoisted and lose the outer if-narrowing that inline
arrow-function closures previously relied on.
* refactor(func-style): convert const-arrow functions to declarations across util/manager/datasource modules
One case (logger/renovate-logger.ts logOnceFn) is kept as an arrow
function with a documented oxlint-disable: it is stored on
this.logger.once[level] and relies on lexically-bound this, which a
hoisted function declaration would not preserve.
* refactor(func-style): convert remaining const-arrow test helpers to declarations
get-updated.spec.ts: hoisted expectPipCompilePackageAndLockFile to
module scope (it only closes over the module-level pipCompile mock)
and added a documented oxlint-disable for vitest/expect-expect on its
caller test, since oxlint's expect-expect check does not trace
assertions through an externally-defined helper function.
