feat(drive): add +copy shortcut

Wrap the Drive file-copy endpoint as drive +copy. Accept a document URL
(recommended) or bare token + --type for the source; the target takes a
folder token, a folder URL, or the my_space constant, which resolves the
caller's My Space root folder via the root-folder-meta endpoint (absent
from platform metadata, works for both user and bot). Repeatable --extra
key=value pairs are forwarded verbatim for special copy semantics (e.g.
target_type=docx to convert a legacy doc during copy). Reject wiki
URLs/tokens with a typed validation error whose hint carries a
ready-to-adapt wiki +node-copy command, because a Drive copy of a
wiki-backed document would land in Drive space instead of the wiki tree.

Declare docs:document:copy (the narrowest scope in the endpoint's any-of
set) plus a conditional drive:drive.metadata:readonly for my_space
resolution. Cover the shortcut with unit tests, dry-run e2e and a
self-contained live workflow (upload -> copy -> download-verify ->
my_space copy -> cleanup), and register it in
tests/cli_e2e/drive/coverage.md. Route copy intents in the lark-drive
skill to the shortcut instead of the raw files copy service command.

 We recommend using the Lark/Feishu bot integrated with this tool as a private conversational assistant. Do not add it to group chats or allow other users to interact with it, to avoid abuse of permissions or data leakage.
 
+To reduce the security risks associated with access token theft, the CLI sends a minimal set of risk-control signals with OpenAPI requests made to exact official Feishu/Lark HTTPS domains. These signals are used to help identify anomalous API activity. This protection is enabled by default. The information sent is limited to:

+- Device hardware model: for example, Mac17,9

+To disable this protection for the current workspace, run:

+## +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.
