feat(activity): flat-upload-manifest arm in extractAttachmentsFromRequestBody

Adds a second walk arm for the canvas chat_upload_receive shape: a flat upload manifest at request_body root (no JSON-RPC envelope) with camelCase mimeType. Normalizes to snake_case mime_type on emit + derives kind from the mime prefix (image/* -> image, audio/* -> audio, video/* -> video, else -> file). Empirical surface: 2026-05-21 ~23:12Z canvas-user pasted a PNG, the activity row's request_body was {uri, name, size, file_id, mimeType} with no params/message/parts wrapper, and ?include=peer_info projected attachments: null instead of the expected one-element array. The new arm handles this shape uniformly so every downstream adaptor (channel / telegram / codex / hermes) sees a populated attachments[] with zero per-adaptor parsing. Per the three-layer data-responsibility rule (platform / base / adaptor), upload-shape parsing belongs at Layer 1 (the platform's projection), not in adaptors. Tests: - TestKindFromMimeType (12 cases) pins the mime->kind derivation. - TestExtractAttachmentsFromRequestBody_FlatUpload_* (8 sub-tests) cover image / audio / video / generic-file / no-mime-fallback / snake-case mime_type accepted / file_id-only-skipped / name-only-kept. - TestExtractAttachmentsFromRequestBody_MessagePartsTakesPrecedenceOverFlat pins that a pathological body with BOTH shapes uses the parts[] arm (the documented inbound, historically the only one extracted). - TestActivityList_IncludePeerInfo_ChatUploadReceiveCanvasRow is a wire- level integration test against the empirical 2026-05-21 row shape. Follow-up: workspace-runtime#37's _extract_attachments_from_request_body gets the same flat-upload arm for pre-Layer-1 platform parity. Not required for already-L1-enabled platforms (which read the row-level attachments[] field this projection populates). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
