Replace "seam" with clearer terms throughout:
- "surface" for public API/extension boundaries
- "boundary" for plugin/module interfaces
- "interface" for runtime connection points
- "hook" for test injection points
- "palette" for the lobster palette reference
Also delete experiments/acp-pluginification-architecture-plan.md

* 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
* refactor: move Discord channel implementation to extensions/discord/src/
Move all Discord source files from src/discord/ to extensions/discord/src/,
following the extension migration pattern. Source files in src/discord/ are
replaced with re-export shims. Channel-plugin files from
src/channels/plugins/*/discord* are similarly moved and shimmed.
- Copy all .ts source files preserving subdirectory structure (monitor/, voice/)
- Move channel-plugin files (actions, normalize, onboarding, outbound, status-issues)
- Fix all relative imports to use correct paths from new location
- Create re-export shims at original locations for backward compatibility
- Delete test files from shim locations (tests live in extension now)
- Update tsconfig.plugin-sdk.dts.json rootDir from "src" to "." to accommodate
extension files outside src/
- Update write-plugin-sdk-entry-dts.ts to match new declaration output paths
* fix: add importOriginal to thread-bindings session-meta mock for extensions test
* style: fix formatting in thread-bindings lifecycle test
Signal reactions required an explicit messageId parameter, unlike
Telegram which already fell back to toolContext.currentMessageId.
This made agent-initiated reactions fail on Signal because the
inbound message ID was available in tool context but never used.
- Destructure toolContext in Signal action handler
- Fall back to toolContext.currentMessageId when messageId omitted
- Update reaction schema descriptions (not Telegram-specific)
- Add tests for fallback and missing-messageId rejection
Closes#17651
Forum channels that require tags fail with "A tag is required" when
creating threads because there was no way to pass tag IDs. Add
appliedTags parameter to the thread-create action so forum posts can
include required tags from the channel's available_tags list.
* Telegram: soft-fail reactions and fallback to inbound message id
* Telegram: soft-fail missing reaction message id
* Update CHANGELOG.md
