5b93c6216a Fix Chat UI paste intake and pane routing (#23784)
* fix(chat): separate text paste from attachments and route by pane

Keep composer text independent of image checks and saving, and route pastes
caught underneath chat to the originating pane's mounted input. Preserve
native event data, selection replacement, undo, and target lifetime checks.

* fix(chat): keep focus and quiet text paste after routing it to chat

- A paste inserted into the composer now moves focus there, as the old
  menu-paste insert did; otherwise a paste routed from the hidden terminal
  left the next keystrokes going to that terminal.
- With a remote-server or not-ready workspace, pasted text no longer shows
  the "Local attachments are not available" refusal because the clipboard
  also held an image rendition (common for Office copies). The menu path
  probes for an image only when the text read is empty, so a paired browser
  does one permission-gated clipboard read for a text paste, not two.
- Latest-value refs update in a layout effect instead of during render.

* perf(clipboard): answer "is there an image?" from the format list

The chat composer asks the main process whether the clipboard holds an
image before explaining an image-only paste on a remote-server workspace.
That probe decoded the whole image (readImage().isEmpty()) on the main
thread just to return a boolean. Read clipboard.availableFormats() instead,
and share the MIME check with the paired-web probe.

* fix(chat): a chat cover owns focus, so input never reaches the hidden terminal

When a Chat UI tab opened over its terminal, the terminal's xterm kept
keyboard focus until the composer claimed it a frame later, and forever if
the composer never became ready (still starting, a question card, a phone
holding input). The previous commits rerouted paste from that hidden
terminal to the chat, but typing and Enter still went to the terminal, an
image-only or refused paste left focus there, and about twenty
terminal.focus() call sites could put it back.

Make "a covered terminal cannot hold focus" structural instead:
- The chat cover takes focus in the commit that mounts it and marks the
  covered xterm inert, so every terminal.focus() path is refused by the
  browser. Split siblings are untouched. When the chat goes away the xterm is
  un-inerted, and gets focus back only if focus was inside that chat.
- Terminal paste listeners skip anything inside a chat cover (previously only
  inside a mounted chat root). The reroute from terminal to chat is gone;
  terminal-only paste is back to main's code.
- A paste that finds no chat input (before the chat mounts, or an approval
  card with no text field) gets a visible refusal from the cover. A disabled
  composer shows the same notice inline instead of dropping the paste. New
  copy: "Can't paste — this chat isn't accepting input right now." (the old
  "Worktree not ready" toast was wrong for a chat that is still starting).
- The terminal context menu, which names its pane, keeps a small request
  event to that pane's chat, now without a clipboard payload and using the
  existing covered-pane check.
- Cmd/Ctrl+V or Shift+Insert on a non-input part of the chat focuses the
  composer (or question answer) first, so the paste lands there.
- The composer-scope check used to decide whether a text field inside the
  chat keeps its own paste matched the whole pane (the file-drop surface
  carries the same attribute). It now asks the composer whether the target
  is inside its input.

* fix(chat): don't paste a copied file's name next to the file

Copying a file in Finder or another file manager puts its name on the
clipboard as text/plain beside the file itself. Since text and images are
now pasted independently, pasting such a copy into a local or SSH chat
inserted the file name into the prompt as well as attaching the image.

On the paste-event path, text/plain that is exactly the names of the pasted
files (one per line) is the file's label, not prompt text, so it is dropped
when an image from that paste is being attached. Rich-text copies (text plus
an image rendition) still insert their text, and a copied non-image file,
which is not attached, still pastes its name as before.

* fix(chat): don't type a Finder file's name on Cmd+V either

On macOS, Cmd+V in the chat goes through the app-menu paste, which reads the
clipboard text and saves the clipboard image separately. A file copied in
Finder also puts its name on the clipboard as text, so the composer typed
the name next to the attachment. On main the menu path never read text once
an image saved.

The main process now reports the paths of the files a file manager copied
(macOS filenames plist or file URL, Explorer's FileNameW, a Linux uri-list).
Text that only labels those files waits for the image outcome: dropped when
an image is attached (or refused on a remote owner), typed when none came.
The same label rule now also accepts a path or file URL per line, which is
how Linux file managers label copied files on the paste-event path.

* fix(chat): pane focus aimed at a chat lands on the chat

Since the covered terminal became inert, focusing a pane that shows a chat
(keyboard pane navigation, focus-follows-mouse, split activation) was refused
and focus stayed on the pane the user left, so typing went to that visible
sibling terminal. The one place a pane's focus is requested now puts it on the
pane's chat cover, which hands it to the composer when the pane is revealed.
Focus already inside the chat is left alone.

* test(terminal): give fake panes the container pane focus now reads

Pane focus checks the pane's container for a chat cover, and these two
fixtures built panes with only a terminal, so four tests threw.

* refactor(native-chat): move composer paste handle and chat-root key routing into their own modules

Brings NativeChatComposer.tsx and NativeChatResolvedView.tsx back under the
400-line limit after merging main. No behavior change.
