Accumulating milestone branch. One squashed commit per closed issue; `next` is kept green and mergeable to `main` at any time without notice.
Landed so far:
- `chore: update golangci-lint to v2.12.2 with canonical config` (#54) — canonical v2-schema `.golangci.yml`, pins bumped in `Dockerfile` and `script/bootstrap`, tree at `0 issues.`. Three behaviour deltas are recorded in that PR's body: `Cache.StoreVariant` takes a context, `MetadataStorage.Store` no longer leaks temp files on failure, and the `signing_key` too-short error text gained a `value too short:` prefix.
Sequencing for the milestone is tracked in #103.

Extract `HostWhitelist`, `NewHostWhitelist`, `IsWhitelisted`, `IsEmpty`, and `Count` from `internal/imgcache/` into the new `internal/whitelist/` package.
The whitelist package is completely self-contained, depending only on `net/url` and `strings` from the standard library. No circular imports introduced.
**Changes:**
- Moved `whitelist.go` → `internal/whitelist/whitelist.go` (added package comment)
- Moved `whitelist_test.go` → `internal/whitelist/whitelist_test.go` (adapted to external test style)
- Updated `internal/imgcache/service.go` to import from `sneak.berlin/go/pixa/internal/whitelist`
`docker build .` passes (lint, tests, build).
