* feat(lint): add renovate/prefer-fs-util and renovate/prefer-luxon rules
Two shared-util substitution rules, both at warn level:
- renovate/prefer-fs-util flags value imports of fs, node:fs,
fs/promises, node:fs/promises, fs-extra and fs-extra/esm in lib/
source files outside lib/util/fs/, pointing to the scoped helpers
from lib/util/fs. Spec files and type-only imports are exempt.
A config-only change via no-restricted-imports was considered but
rejected: that rule is at error severity globally and per-path warn
severity is not expressible, so the 13 existing call sites would
break the baseline.
- renovate/prefer-luxon flags new Date(...) and Date.now() in lib/
source files, pointing to Luxon per best-practices. Date/time
utility modules (lib/util/date, lib/util/pretty-time,
lib/util/timestamp) and spec files (vi.setSystemTime etc.) are
exempt.
Baseline: 13 prefer-fs-util and 45 prefer-luxon warnings, zero errors.

* refactor: use Luxon instead of new Date() at remaining call sites
Fixes all renovate/prefer-luxon violations for `new Date(...)`:
- `new Date().toISOString()` -> `DateTime.utc().toISO()` (byte-identical
output) in the http cache provider, schedule logging and PR cache.
- `new Date()` -> `DateTime.now().toJSDate()` for the git commit-date
fallback and the rubygems `syncedAt` markers (same `Date` values).
- rust-release-channel now computes the Rust 1.0 release date and nightly
version dates via `DateTime.utc(...)`; previously `new Date(y, m, d)`
used the local timezone while the epoch used UTC, so the comparison was
timezone-dependent at the boundary date. Tests run with TZ=UTC, where
behavior is unchanged.

* refactor: use lib/util/fs helpers in repository worker
Fixes renovate/prefer-fs-util violations outside bootstrap code:
- `fs.ensureDir()` -> `ensureDir()` from lib/util/fs (same fs-extra call
underneath; it no-ops on an empty dir name, so the repository worker
spec now simulates the init failure via a rejected `initRepo` instead
of relying on `fs.ensureDir('')` throwing).
- `fs.remove(privateCacheDir())` -> `cachePathExists()` + `rmCache()`,
keeping the remove-if-present semantics while asserting cacheDir
containment.
Two call sites keep raw imports with reasoned disable comments:
- lib/util/modules.ts synchronously enumerates Renovate's own installed
module directories at import time.
- lib/util/cache/package/impl/sqlite.ts receives cacheDir as an explicit
argument during global initialization, before GlobalConfig (which the
scoped cache helpers resolve against) contains cacheDir.

* feat(lint): promote prefer-fs-util and prefer-luxon to error
Both rules are narrowed to what is actually accepted practice before
being promoted:
prefer-luxon no longer flags `Date.now()`: it returns UTC-based epoch
milliseconds used for elapsed-time measurement and TTL arithmetic, which
is timezone-independent by construction. The mined reviewer feedback
behind this rule ("use Luxon for date arithmetic outside util") targets
timezone-dependent date construction/formatting, which cannot occur with
a raw millis number; the rule keeps flagging `new Date(...)`.
prefer-fs-util exempts code that legitimately needs raw fs access
because the scoped lib/util/fs helpers resolve against GlobalConfig
localDir/cacheDir, which does not exist yet or does not apply there:
- lib/logger/: log-file streams at user-configured system paths during
bootstrap; lib/util/fs also depends on the logger (import cycle).
- lib/workers/global/: creates baseDir/cacheDir themselves and
reads/writes user-supplied paths before GlobalConfig is seeded.
- lib/config-validator.ts: standalone CLI without GlobalConfig.
- lib/util/git/: owns the localDir lifecycle (clone, emptyDir, symlinks)
and private-key files with sync cleanup on process exit.
Also fixes a pre-existing tsc error in prefer-fs-util.js: `importKind`
is a TypeScript-ESTree extension missing from eslint's base AST types.

* refactor(fs): make rmCache ignore missing paths
All rmCache callers use it for cleanup, where a missing path is a
no-op, so bake force: true in instead of guarding call sites with
an existence check.

* refactor(linters): exempt lib/instrumentation from prefer-fs-util
`lib/instrumentation/file-exporter.ts` landed on main while this branch
was open and imports `node:fs/promises` directly.
The exporter writes to a user-configured system path
(`RENOVATE_TRACING_FILE_EXPORTER_PATH`) outside `localDir`/`cacheDir`,
so the scoped helpers do not apply. `lib/instrumentation` is also
deliberately kept out of the module graph of instrumented libraries
(see the `⚠️` note in `lib/renovate.ts`), so it must not pull in
`lib/util/fs` and its config/logger dependencies. Exempt the directory,
as is already done for `lib/logger`.
