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.

+## +search-bot
+Search bots (apps) by keyword. Pass `--query` or `--queries`; use `--chat-ids` to search within specific chats.
+
+### Skills
+- lark-contact/references/lark-contact-search-bot.md
+
+### Avoid when
+- Looking for a person rather than a bot → use [[+search-user]]
+- Running as a bot — this shortcut is user-only
+
+### Tips
+- `has_more=true` means the search is incomplete; refine the keyword or search scope instead of paginating
+
+### Examples
+
+**Find bots by keyword**
+```bash
+lark-cli contact +search-bot --query "会议助手" --as user
+```
+
+**Search inside one chat**
+```bash
+lark-cli contact +search-bot --query "助手" --chat-ids "oc_3a8b****6a7b" --as user
+```
+
+**Find bots you've chatted with**
+```bash
+lark-cli contact +search-bot --query "助手" --has-chatted --as user
+```
+
+**Search several bot keywords in one call**
+```bash
+lark-cli contact +search-bot --queries "会议助手,日报助手,审批助手" --as user
+```
+
 ## +get-user
 Fetch one user's profile by id, or your own with --user-id omitted. Use it under bot identity — `+search-user` is user-only.
