Merge remote-tracking branch 'origin/main' into refactor/package-debt-phase2

main brought behaviour, this branch brought renames, so every resolution keeps
both. Nothing had to be given up.

Two textual conflicts:

- lint/domaincontract/scan.go: the package comment. Took main's wording, which
  describes the domain policy it just added and names no package, so this
  branch's edit — replacing a stale internal/core reference — needs nothing
  carried over. The behaviour-bearing line in the same file, resolverPath
  pointing at brand/brand.go, sits outside the conflict and is untouched.
- shortcuts/drive/drive_io_test.go: the import block, resolved as the union of
  main's credential and validate with this branch's config and identity.

Four more the merge resolved silently and wrongly, because #2070 added files
naming a package this branch deletes. They compile only after rewriting:
core.LarkBrand to brandpkg.Brand, core.BrandLark to brandpkg.Lark and
core.ResolveOpenBaseURL to brand.ResolveOpenBaseURL, across
drive_permission_get_setting.go, its test, and drive_io_test.go. The production
file needs the brandpkg alias because a local variable there is already named
brand. Diffing those files against main afterwards shows the import line and
the symbol names as the only differences, so #2070's host selection is intact.

Worth recording for the next merge: main's new drive test imports
internal/credential, which shortcuts-runtime-gate denies and which this branch
now also checks in test files. It passes only because internal/credential is
one of the rule's TestExempt entries. A denied import outside that list would
have forced a real choice.
