* fix(client): serialize X11 keyboard grab and debounce focus feedback
When two RustDesk sessions run fullscreen on separate monitors on
Linux/X11, keyboard input gets stuck on the wrong session or stops
working entirely. This happens because each Flutter isolate calls
change_grab_status concurrently, racing on KEYBOARD_HOOKED and the
rdev grab channel.
Additionally, XGrabKeyboard causes a focus-change feedback loop:
grab shifts focus away from the Flutter window, triggering PointerExit,
which releases the grab, restoring focus, triggering PointerEnter,
which re-grabs -- cycling at ~10 Hz and blocking keyboard input.
Fix by:
- Serializing grab transitions with a mutex and tracking the owning
session (by lc.session_id), so a stale Wait from session A cannot
clobber session B's freshly acquired grab.
- Debouncing Wait events (300 ms) from the same session that just
acquired the grab, breaking the X11 focus feedback loop.
- Refreshing the debounce timer on idempotent Run calls (enterView
while already owner), keeping the grab stable during normal use.

* fix(client): add deferred release and dedup for debounced Wait
When a Wait is debounced (within 300ms of grab acquisition), schedule
a deferred release thread that re-checks after the debounce window.
If no new Run refreshed the grab, the deferred thread releases it,
ensuring a genuine leave within the debounce window is not lost.
Add a deferred_pending flag to GrabOwnerState to prevent spawning
redundant threads during the X11 focus feedback loop.

* fix(client): use window-scoped ID and fix deferred-release re-arming
Address PR review feedback:
- Use per-window UUID instead of connection-scoped lc.session_id so two
windows viewing the same peer get distinct grab owners
- Reset deferred_pending on both idempotent Run refresh and owner
handoff, so a subsequent Wait can always spawn a fresh timer
- Replace manual Default impl with derive
* fix(client): recover from poisoned mutex instead of panicking
* docs: clarify cross-platform rationale for GrabOwnerState
* fix(client): only clear deferred_pending when timer snapshot matches
* fix(client): use full u128 window ID, downgrade grab logs to debug
- Widen GrabOwnerState.owner to u128 to avoid theoretical collision
from truncating a 128-bit UUID to 64 bits
- Downgrade all grab transition log::info! to log::debug! to reduce
log noise during routine window switches
- Clear deferred_pending on post-debounce release path to maintain
the "deferred_pending => timer in flight" invariant
* fix(client): gate GRAB_DEBOUNCE_MS with cfg(target_os = "linux")
* fix(grab): release grabbed keys without clobbering new owner state

* feat: Add relative mouse mode
- Add "Relative Mouse Mode" toggle in desktop toolbar and bind to InputModel
- Implement relative mouse movement path: Flutter pointer deltas -> `type: move_relative` -> new `MOUSE_TYPE_MOVE_RELATIVE` in Rust
- In server input service, simulate relative movement via Enigo and keep latest cursor position in sync
- Track pointer-lock center in Flutter (local widget + screen coordinates) and re-center OS cursor after each relative move
- Update pointer-lock center on window move/resize/restore/maximize and when remote display geometry changes
- Hide local cursor when relative mouse mode is active (both Flutter cursor and OS cursor), restore on leave/disable
- On Windows, clip OS cursor to the window rect while in relative mode and release clip when leaving/turning off
- Implement platform helpers: `get_cursor_pos`, `set_cursor_pos`, `show_cursor`, `clip_cursor` (no-op clip/hide on Linux for now)
- Add keyboard shortcut Ctrl+Alt+Shift+M to toggle relative mode (enabled by default, works on all platforms)
- Remove `enable-relative-mouse-shortcut` config option - shortcut is now always available when keyboard permission is granted
- Handle window blur/focus/minimize events to properly release/restore cursor constraints
- Add MOUSE_TYPE_MASK constant and unit tests for mouse event constants
Note: Relative mouse mode state is NOT persisted to config (session-only).
Note: On Linux, show_cursor and clip_cursor are no-ops; cursor hiding is handled by Flutter side.

Previously, on-flight frames after clearing the queue could not be decoded successfully. This issue can be resolved by setting a discard_queue flag when sending a refresh message. The flag will be reset upon receiving a keyframe.

* Calculate fps without distinguish displays, use one fps control
because the controlled side control fps of all displays with one FPS
variable.
* Because all displays decode frame in one thread, when there are N
displays, the video frames received in one second is `fps * N`, so the
calculated decode fps should be divided by N. Because the actual
display count is not obvious in rust, when no data frame is received for 5 seconds, the display is considered inactive, and only the active display is used as the dividend.
