…rtial-delivery notices - When an agent message contains workspace attachment paths like (/workspace/group/attachments/image.jpg), route them to Grammy's sendPhoto/sendDocument via the Telegram Bot API instead of plain text. - Security: extractWorkspaceAttachmentPaths now rejects any path whose segments include '..', preventing path traversal extraction at the source. The new wrapTelegramDriverForMedia wrapper adds a second containment check after path.resolve() to guard against symlink escapes. - Partial delivery: per-attachment failures are tracked individually. After the send loop, any failures produce a visible⚠️ user-facing notice via sendMessage. Long-caption follow-up failures also send a visible notice. - sendTelegramMedia is injectable via AgentRuntimeOptions for testing. - Regression tests added: - rejects path traversal in outbound Telegram attachment paths - sends visible error notice when second attachment fails to deliver Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
