Add the remote_mouse tool to the MCP remote control surface, injecting
mouse events (move / down / up / click / right_click / middle_click /
drag / scroll) into an established remote_open session. Normalized 0..1
coordinates are mapped to physical pixels via the session's captured
resolution and clamped to screen bounds. Scroll follows the existing web
console's wheel sign convention (positive delta scrolls down) and is
vertical-only.
Extract BuildMouseMsg64 into WebService.h as a shared helper, reused by
both the web console's HandleMouse and the new MCP handler so the two
injection paths cannot drift.

Implement milestone M2b of the MCP remote-control design: inject keyboard
events through an existing screen sub-connection.
- Extract the MSG64 keyboard construction from WebService::HandleKey into a
shared inline BuildKeyMsg64 helper in WebService.h, and have HandleKey use
it (behaviour-preserving) so the Web and MCP paths cannot drift.
- Add BuildRemoteKeyboard with four actions: key_down / key_up / key_press
(key name -> VK via MapKeyNameToVk, plus CTRL/ALT/SHIFT/WIN modifiers) and
type (per-character VkKeyScanA mapping, ASCII only, newline/tab -> Enter/Tab).
The batch is sent as one [COMMAND_SCREEN_CONTROL][MSG64*N] packet over the
screen sub-connection under the existing Begin/EndScreenCtrlAction busy
discipline, then audited via WM_SHOWERRORMSG.
Non-ASCII text is rejected (-32602) and must go through remote_clipboard +
Ctrl+V (milestone M4), matching the design's clipboard path for CJK input.

Add M1 of MCP remote control (docs/Mcp_RemoteControl_Design.md): the
remote_open / remote_close tools plus the ScreenCtrlSession state machine.
remote_open establishes a hidden screen sub-connection by reusing
WebService::StartRemoteDesktop (COMMAND_SCREEN_SPY -> CScreenSpyDlg ->
RegisterScreenContext), polls for the sub-connection plus its physical
resolution (TOKEN_BITMAPINFO -> NotifyResolutionChange -> GetScreenSize),
then records the session (single device, single session, reverse-mapped
subCtx for OfflineProc cleanup) and returns {session_id, screen_w,
screen_h}. remote_close validates session_id and tears down the
sub-connection idempotently. A McpRemoteControl settings checkbox (default
off, requires McpReadonly=0) gates the tools; every open/close is audited
via WM_SHOWERRORMSG.
Gating: multi-monitor hosts are rejected with -32008 (phase 1 supports only
single monitor, where Observe=main screen and Act=virtual desktop coincide);
the monitor count comes from the client heartbeat RES_RESOLUTION ("N:W*H").
Known limitations (deferred to the injection milestones): mutual exclusion
with human remote-desktop viewing is one-directional in M1 (a human who
joins during an MCP session can tear it down on disconnect), and subCtx is
not yet dereferenced so no liveness re-check is needed until
remote_mouse/remote_keyboard.

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
