* refactor: remove channel shim directories, point all imports to extensions
Delete the 6 backward-compat shim directories (src/telegram, src/discord,
src/slack, src/signal, src/imessage, src/web) that were re-exporting from
extensions. Update all 112+ source files to import directly from
extensions/{channel}/src/ instead of through the shims.
Also:
- Move src/channels/telegram/ (allow-from, api) to extensions/telegram/src/
- Fix outbound adapters to use resolveOutboundSendDep (fixes 5 pre-existing TS errors)
- Update cross-extension imports (src/web/media.js → extensions/whatsapp/src/media.js)
- Update vitest, tsdown, knip, labeler, and script configs for new paths
- Update guard test allowlists for extension paths
After this, src/ has zero channel-specific implementation code — only the
generic plugin framework remains.
* fix: update raw-fetch guard allowlist line numbers after shim removal
* refactor: document direct extension channel imports
* test: mock transcript module in delivery helpers
Move all Slack channel implementation files from src/slack/ to
extensions/slack/src/ and replace originals with shim re-exports.
This follows the extension migration pattern for channel plugins.
- Copy all .ts files to extensions/slack/src/ (preserving directory
structure: monitor/, http/, monitor/events/, monitor/message-handler/)
- Transform import paths: external src/ imports use relative paths
back to src/, internal slack imports stay relative within extension
- Replace all src/slack/ files with shim re-exports pointing to
the extension copies
- Update tsconfig.plugin-sdk.dts.json rootDir from "src" to "." so
the DTS build can follow shim chains into extensions/
- Update write-plugin-sdk-entry-dts.ts re-export path accordingly
- Preserve extensions/slack/index.ts, package.json, openclaw.plugin.json,
src/channel.ts, src/runtime.ts, src/channel.test.ts (untouched)
