Address copilot comments

Callers cannot detect plugin-side behavior. fzf#exec() reports the version
of the binary, not of this plugin, and everything else here is script-local.
fzf.vim needs to know whether fzf#run is asynchronous in popup mode before
offering a key binding that depends on it.

The value was only ever read through the exists() guard, so raising it from
1 breaks nothing.

-- Fixed an escape sequence split across reads being parsed as a fragment, which leaked the rest into the query (#4899)
-    - e.g. A terminal answering the startup `DECRQM` query late left `?2004;2$y`, CTRL-UP left `5A`, and SGR mouse input left `0;1;1M`
-- Fixed `--tiebreak=pathname` not detecting the last path separator when the line contains a non-ASCII character before it (#4902)
-- Fixed `progress` in the `--listen` status payload staying at 100 while a new search was running, which made a snapshot with a new query and the previous result set look complete (#4903)
-    - It is now reset when a search starts and reaches 100 on the final result, so `progress` of 100 means the matches belong to the query reported next to them
-- Fixed adaptive height not reserving a line for the divider of an inline header or footer border, so the list came up one line short for each of them (#4904)
-    - e.g. `seq 10 | fzf --height=~100% --list-border --header-lines=1 --header-lines-border=inline`
-- Fixed fzf erasing the line the prompt was on when it exits, which made the last line of the prompt flicker in fish, bash, and nushell (#4913)
-- Fixed fzf exiting with status 2 while waiting for a key, when `--listen` is used and 100+ signals interrupt the wait (#4917)

     - fzf no longer blocks the editor, so live previews keep working while fzf is open
