* 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

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.

Enable the unicorn/prefer-at rule as error in .oxlintrc.json and fix all
43 pre-existing violations (arr[arr.length - 1] -> arr.at(-1)) via oxlint
autofix. Where .at() widened the type to T | undefined, non-null
assertions were added at sites where surrounding logic guarantees the
element exists (length guards, split results), preserving the original
runtime behavior and typing.
