Implement the P2 upload_file tool to push a local file or directory from the
master to an online Windows host over the existing V2 file-transfer protocol.
The server drives FileBatchTransferWorkerV2 synchronously on the main
connection through a headless callback, reuses the list_files chain for the
overwrite pre-check, and is gated by McpFileTransfer=1 plus McpReadonly=0.
The client main connection never initialized the file-transfer module, so
g_status stayed 0 and RecvFileChunkV2 silently dropped every chunk, truncating
uploads to zero bytes. Add a once-per-process lazy InitFileUpload in the
COMMAND_SEND_FILE_V2 handler that mirrors the FileManager init; the destructor
deliberately does not Uninit so g_status remains 1 across reconnects.
Update the design doc to record the client-side change and correct the
upload_file description to state that sha256 is not returned (V2 has no
receiver-to-sender ACK; integrity is checked client-side and logged only).

download_file pulls a remote file or directory back to the controller over
the existing V2 file-transfer protocol. It reuses COMMAND_LIST_DRIVE to open
the file-manager sub-link, then sends CMD_DOWN_FILES_V2 so the Windows client
streams COMMAND_SEND_FILE_V2 chunks and a per-file COMMAND_FILE_COMPLETE_V2
SHA-256 checksum over its own authenticated sub-connection. The server routes
those two packet types into a new per-device FileTransferSession whenever a
download is pending, so the headless path never opens the GUI progress dialog;
the C2C and existing GUI branches are left untouched.
Files are written under a normalized local_dir, and every chunk filename is
resolved and verified to stay inside local_dir (directories included) to block
.. traversal; overwrite=false skips existing files and counts them as skipped.
One transfer per host (mutually exclusive with the one-shot pending registry),
a dedicated McpFileTransfer=0-by-default gate surfaced in the settings dialog,
and audit logging complete the change. upload_file remains future work.

Add docs/Mcp_RemoteControl_Design.md, the reference design for an
screenshot-driven AI remote-control feature: the existing get_screenshot for
observation plus remote_open/remote_close/remote_mouse/remote_keyboard for
input injection, reusing COMMAND_SCREEN_PREVIEW_REQ and COMMAND_SCREEN_CONTROL
+ MSG64. Coordinates are normalized (0..1) and mapped server-side to physical
pixels; injection runs over the screen sub-connection opened by
WebService::StartRemoteDesktop's hidden CScreenSpyDlg. Includes a
chat-on-behalf experiment case with clipboard-encoding and window-capture
notes.
Also fold in the get_audit_log encoding correction for
docs/Mcp_Terminal_Design.md, so the two doc changes ship as one commit.

Add terminal_open / terminal_exec / terminal_close so an AI can hold one
shell session per Windows host and run a sequence of commands with cwd and
environment preserved, instead of the one-shot exec_command.
The persistent terminal is a separate full-command write capability gated by
McpTerminal (default off) plus McpReadonly=0, with no whitelist and full
audit. One device maps to one terminal session via the shared m_TermSessions
map; idle sessions are swept after 300s. terminal_exec rejects commands that
contain & or | (they corrupt the sentinel control-operator chain) as well as
control characters.
Also harden exec_command and terminal_exec against newline/CR injection, fix a
dangling subCtx after an abrupt shell disconnect, and refresh lastActiveAt on
command completion. Add en/zh-TW translations for the new UI strings and a
design document covering both exec_command and the persistent terminal.

Add the two P2d read-only MCP tools, both one-shot sub-links (mode A') on
the existing single-flight pending registry.
list_services sends COMMAND_SERVICES; the client's CServicesManager emits
TOKEN_SERVERLIST on sub-link creation, parsed as 5 null-terminated fields per
record (display_name/service_name/binary_path/status/start_type) with
zero-padding termination. Services are Windows-only, so LNX/MAC hosts get
-32005 up front instead of a 20s timeout.
get_client_log sends COMMAND_QUERY_LOG; the client's CClientLogManager dumps
its full in-memory Logger ring buffer once, then pushes deltas every 3s. The
MCP path takes the first (full) TOKEN_REPORT_LOG and cancels the sub-link so
later deltas stop, while the MFC log dialog keeps receiving deltas on the
non-pending branch. Log text is client ANSI on Windows, decoded by clientType
like process/file names. MessageHandle intercepts both with
IsPending -> TakeMainResponse + CancelIO. Sync the design doc (P2d section +
verification notes; Linux get_client_log timeout is a client-version gap).

The get_screenshot tool inherited the MFC thumbnail-preview profile, capping
the frame at 1024px wide (1280 on 4K source), which is too small for AI
vision/OCR of dense UI. Add an optional max_width argument that overrides the
width (clamped to the client's 64..1920 limit) while keeping the RTT-adaptive
jpegQuality. Omitted or 0 keeps the existing thumbnail profile; 1920 yields
near-native resolution (full 1080p on a 1080p source, 1920 wide on 4K). Sync
the design doc.

Add the two P2c MCP tools on top of the P2b protocol. list_files lists
drives (COMMAND_LIST_DRIVE -> TOKEN_DRIVE_LIST) or a directory (follow-up
COMMAND_LIST_FILES -> TOKEN_FILE_LIST on the same one-shot sub-link);
get_screenshot reuses the screen-preview RPC with a per-host reqId
correlation so stale or MFC-preview responses fall through to the MFC
path untouched. Both share the P2b single-flight pending registry.
Fix file/process name encoding: the client reads process names, paths and
file names via the ANSI (A) APIs, so they are GBK on Windows regardless of
the CLIENT_CAP_UTF8 capability bit (which governs window titles only).
Decode by clientType (LNX/MAC = UTF-8, Windows = 936) rather than
GetClientEncoding, and convert the list_files path to the client ANSI code
page before sending. Sync Mcp_Phase2_Design.md with the P2c design and the
encoding correction.

Add three read-only P2b MCP tools over the existing protocol. list_processes and list_windows trigger the client via COMMAND_SYSTEM / COMMAND_WSLIST on the main connection and receive TOKEN_PSLIST / TOKEN_WSLIST on a one-shot sub-link; get_activity_history uses the main-connection RPC COMMAND_QUERY_ACTIVITY -> TOKEN_REPORT_ACTIVITY. A per-host single-flight pending registry (m_Pending) with a 20s timeout correlates each response to its request and rejects a concurrent request for the same host with -32003. Parsers stop on the first empty record to ignore the client's LocalSize trailing zero padding, and window titles are decoded per the client UTF-8 capability bit. MessageHandle only adds if-guarded branches, so the MFC dialogs are untouched. Sync Mcp_Phase2_Design.md with the mode A'/A architecture, the verification notes, and the registry-backed config location.

Add two pure in-memory MCP tools over the online host list. search_hosts filters by name/remark, IP, group and OS (all optional, AND-combined, ASCII case-insensitive substring match); get_host_detail returns one online host by id and answers -32602 for a missing/non-numeric id and -32002 for an unknown or offline id. Sync Mcp_Phase2_Design.md with the second-review corrections and the P2a implementation.

Add an optional MCP server (JSON-RPC 2.0 over Streamable HTTP) exposing
an online-host listing tool, protected by a Bearer token. Disabled by
default; configured via a new "Extensions > MCP Settings" dialog.
- McpServer: httplib + JSON-RPC 2.0 dispatch (initialize/ping/tools/list/tools/call)
- McpSettingsDlg: runtime-created dialog for enable/port/bind/token
- HostJson: extract single-host JSON serialization shared with WebService
- FRP: expose MCP port (union with listening/Web ports) when bound to 0.0.0.0
- i18n: en_US / zh_TW translations
