feat: Finder-style mouse selection (Ctrl-click, Shift-click, double-click, right-click)

Add macOS Finder-style mouse interaction to the file list:

- Ctrl/Cmd-click toggles individual file selection
- Shift-click range-selects from anchor point via toggle_all
- Double-click opens files / enters directories
- Right-click opens interactive picker ("Open with...")
- Click dismisses any open dialog and falls through to normal handling
- Selections clear and anchor resets on directory change

Exposes is_ctrl, is_shift, is_super modifier fields on MouseEvent
Lua binding (crossterm already provides them, just not exposed).

See FINDER_MOUSE_SELECTION.md for full design rationale.

+# Finder-Style Mouse Selection
+
+## What this does
+
+This adds macOS Finder-style mouse selection to Yazi's file list:
+
+- **Left-click** — moves cursor to the clicked file (unchanged behavior)
+- **Ctrl-click** (or Cmd/Super-click) — toggles individual file selection
+- **Shift-click** — range-selects all files between the last anchor point and the clicked file
+- **Double-click** — opens the file or enters the directory
+- **Right-click** — opens the "Open with..." interactive picker
+
+The **anchor point** tracks the last file you explicitly interacted with. It's set on every click and reset when you navigate to a new directory. When entering a directory, the anchor defaults to whichever file is highlighted, so Shift-click works immediately without a prior click.
+
+Selections are cleared automatically on directory change to prevent accidental operations on files you can no longer see.
+
+## Why
+
+Yazi already has excellent keyboard-driven selection (visual mode, Space to toggle), but mouse users have no way to select files without the keyboard. Every major file manager — Finder, Nautilus, Dolphin, Windows Explorer — supports modifier-click selection. This brings Yazi up to parity with those conventions.
+
+The feature is entirely opt-in: if you don't use a mouse, nothing changes. All existing keyboard workflows are unaffected.
+
+## What changed (3 files)
+
+### 1. `yazi-binding/src/mouse.rs` — Expose modifier keys to Lua
+
+crossterm's `MouseEvent` already carries a `modifiers: KeyModifiers` field, but it wasn't exposed to Lua. Added three boolean fields following the exact pattern of the existing `is_left`/`is_right`/`is_middle` fields:
+
+```rust
+fields.add_field_method_get("is_ctrl", |_, me| {
+    Ok(me.modifiers.contains(KeyModifiers::CONTROL))
+});
+fields.add_field_method_get("is_shift", |_, me| {
+    Ok(me.modifiers.contains(KeyModifiers::SHIFT))
+});
+fields.add_field_method_get("is_super", |_, me| {
+    Ok(me.modifiers.contains(KeyModifiers::SUPER))
+});
+```
+
+`KeyModifiers` is imported at the top level alongside the existing `MouseButton` import, matching the file's convention.
+
+This is a general-purpose addition — any plugin or preset component can now read modifier state on mouse events.
+
+### 2. `yazi-plugin/preset/components/current.lua` — Click handler
+
+Replaced the minimal `Current:click` with a modifier-aware handler. Key decisions:
+
+- **State lives on the class table** (`Current._anchor`, `Current._last_click`, `Current._cwd`), not on instances. This is consistent with how `Entity._inc` and `Entity._children` persist across render cycles — instances are recreated each frame via `Root:build()`, but class-level fields survive.
+
+- **Batch selection uses `toggle_all`** with a URL array and `state = "on"`, the same pattern used by `fzf.lua` (line 32-33). No per-file toggle loop, no new Rust actors.
+
+- **Double-click detection** uses `ya.time()` with a 0.4s threshold on the same row, consistent with how `mime-local.lua` and `folder.lua` use `ya.time()` for timing.
+
+- **Both Ctrl and Super modifiers** are accepted for toggle-click. Super (Cmd) is the Finder convention on macOS, but many terminals intercept it. Ctrl is the universal fallback and matches Windows/Linux conventions.
+
+- **Directory change detection** compares `tostring(self._folder.cwd)` against `Current._cwd` and resets the anchor + clears selections when it changes. This prevents stale anchors from a previous directory and avoids accidentally operating on invisible selections.
+
+### 3. `yazi-plugin/preset/components/root.lua` — Dialog dismiss on click
+
+Previously, `Root:click` returned early when `cx.layer ~= "mgr"` (i.e., when any dialog was open), swallowing all mouse events. Now it dismisses the dialog and falls through to normal click handling:
+
+```lua
+if tostring(cx.layer) ~= "mgr" then
+    if up then return end
+    ya.emit(tostring(cx.layer) .. ":close", {})
+end
+```
+
+This uses the `layer:command` routing syntax from `Cmd::new` — the command name prefix selects the target layer. So `pick:close` dismisses the "Open with..." picker, `input:close` dismisses text inputs, `confirm:close` dismisses confirmations, etc. No hardcoded layer names.
+
+The `up` guard prevents the mouse-up event from the same click that opened the dialog from immediately dismissing it.
+
+The fall-through (no `return` after close) means right-clicking a different file while a dialog is open will: close the current dialog → reveal the new file → open the dialog for it — all in one click, matching Finder's behavior.
+
+## Problems solved along the way
+
+1. **Modifier keys weren't available in Lua** — crossterm provides them, but yazi-binding didn't expose them. A 9-line addition to `mouse.rs`.
+
+2. **`ya.emit()` always routes to the Mgr layer** — discovered via `call.rs` line 11: `Some(Layer::Mgr)`. Initially tried `ya.emit("escape", {})` and `ya.emit("close", {})` to dismiss dialogs, both hit the wrong layer. The `layer:command` prefix syntax (from `Cmd::new`'s name parsing) solved it.
+
+3. **Mouse-up from the same click dismissed the dialog** — right-click fires both Down (opens dialog) and Up (was dismissing it). Added an `up` guard so only Down events trigger close.
+
+4. **Terminal intercepting Shift-click** — Shift-click is typically reserved for terminal text selection. Solved with XTSHIFTESCAPE escape sequences in the shell launcher wrapper:
+   ```sh
+   printf '\e[>1s'  # tell terminal to pass shift-clicks to application
+   yazi "$@"
+   printf '\e[>0s'  # restore terminal shift-click handling on exit
+   ```
+
+5. **Terminal intercepting right-click** — Ghostty (and many terminals) show a context menu on right-click, consuming the event before it reaches the application. Solved with a Ghostty config setting:
+   ```
+   right-click-action = ignore
+   ```
+   This passes right-click through to all terminal applications globally. Other terminals will have equivalent settings.
+
+## Cross-platform compatibility
+
+The implementation is fully cross-platform. No macOS-specific code.
+
+- **Ctrl-click** — works in all terminals on all platforms (primary modifier)
+- **Super/Cmd-click** — works where the terminal passes Super through (Ghostty, Kitty, iTerm2 on macOS; some Linux terminals)
+- **Shift-click** — works where the terminal supports XTSHIFTESCAPE or doesn't intercept Shift-click for text selection. This is a terminal configuration concern, not a Yazi concern
+- **Double-click and right-click** — standard mouse events, universally supported
+- **Right-click passthrough** — requires terminal not intercepting it for a context menu (e.g., Ghostty's `right-click-action = ignore`)
+
+Terminal-level configuration (XTSHIFTESCAPE, right-click passthrough) is external to Yazi and can be handled in wrapper scripts or terminal config. Yazi itself just reads the modifier flags that crossterm provides.
+
+## What stays unchanged
+
+- **entity.lua** — untouched; plain left-click and right-click delegate to `Entity:click` for the default behavior path
+- **Rust selection system** — `Selected`, `toggle`, `toggle_all`, `visual_mode` all used as-is
+- **No new Rust actors, structs, or event types**
+- **Keyboard workflows** — visual mode, Space toggle, all keybindings work exactly as before
+- **Scroll and touch handlers** — unchanged
