kshitijk4poor ab2f4602de refactor: MessageEvent to gateway/platforms/event.py; ElicitationHandler takes a call_context thunk
Breaks the two import cycles that forced Protocol stand-ins in the F821 sweep, so the two
sites now name the real types.

gateway/platforms/event.py (new leaf): MessageType, ProcessingOutcome, MessageEvent moved
out of base.py verbatim. Their only dependency is gateway.session.SessionSource; base.py
imported helpers.py at module level, so helpers could not name MessageEvent. Now
TextBatchAggregator is typed by the real MessageEvent. 249 importers repointed
(`from gateway.platforms.base import` -> `.event`, preserving each import's layout);
gateway.platforms.__init__ re-exports from .event. The three revert-scheduled PLUGIN-COMPAT
pointers that named these symbols (gateway.slash_commands → MessageType, dingtalk → MessageType,
photon → ProcessingOutcome) and their COMPAT_MANIFEST rows now target gateway.platforms.event.
Docs updated: ADDING_A_PLATFORM.md, adding-platform-adapters.md (en + zh-Hans).

tools/mcp_tool_sampling.py: ElicitationHandler no longer holds a back-reference to its
MCPServerTask (mcp_tool imports sampling, so the task type cannot be named there). It only
ever read owner._pending_call_context, so it takes `call_context: Callable[[], Context | None]`
and MCPServerTask passes `lambda: self._pending_call_context`. The consent call is one
`functools.partial`, run directly or inside the captured Context.

ty on the 11 touched production files vs origin/main: 0 new diagnostics, 14 resolved.
(The one `source: SessionSource = None` diagnostic moves with the class; typing it Optional
exposes ~60 unguarded call sites — separate follow-up.)

Tests: tests/gateway + tests/plugins + tests/tools + touched files, 18,235 passed; the 31
failures reproduce identically on origin/main (macOS /private/tmp, systemd socket,
long-path fixtures, live-service tests).

"""Regression tests for mixed-attachment routing in gateway/run.py.
Issue #25935: when a message mixes a real image with a document (e.g. a .md
brief), Discord types the whole message MessageType.PHOTO. The per-attachment
loops must classify each attachment by its OWN mimetype:
* A document must NOT be swept into image_paths just because the message-level
type is PHOTO — mislabelling it as an image sent its bytes to the vision
endpoint, which rejected them with a non-retryable HTTP 400 and killed the
whole turn ("Could not process image").
* That same document must STILL reach the agent as a readable cached file via
the document context-note path, even though the message-level type isn't
DOCUMENT.
The message-level fallback (PHOTO/VOICE/AUDIO/VIDEO) is preserved only for
attachments whose per-file mimetype is unknown (empty) — platforms that don't
populate media_types.
