feat(remote): open WSL projects through a WSL transport (#989)

* perf(vfs): list directories off the main thread and reuse the repository lookup

Opening a folder on a network share (\\wsl.localhost\<distro>\...) is slow
because every listing ran on the main thread and walked up to the repository
root and ran a repository discovery again.

- fs_read_dir runs on the blocking pool.
- GitignoreStack::cached keeps the repository root and the repo-level rules
  for a few seconds. An edit of .git/info/exclude is still seen at once (its
  mtime and size are checked) and every .gitignore / .ignore is read fresh.

* feat(remote): open WSL projects through a WSL transport

A folder of a WSL distro (\\wsl.localhost\<distro>\... or \\wsl$\...) now opens
as a remote project whose openidea-server runs inside the distro, so the
terminal, SDK discovery, run, language servers and git are native Linux.

- RemoteTarget (ssh | wsl) replaces the SSH configuration id in the remote
  launch, connection, session and recents; old recents are read as SSH and a
  WSL target never inherits the legacy trust migration.
- remote_wsl: probe the distro, stream the server into ~/.openidea/server and
  start it with `wsl.exe -d <distro> --exec <bin> --stdio`. Distro names are
  validated and every command goes through --exec with positional arguments.
- wsl_distros / wsl_resolve commands; File > Open, the CLI and recents route
  WSL folders to the distro and focus the window that already has them.
- Remote Development dialog: SSH/WSL choice with the detected distros; the
  status bar shows `WSL: <distro>` / `SSH: <host>`.
- ide-jsonrpc: skip the NUL left at the start of a line by UTF-16 output of
  wsl.exe, which made the first message of the server disappear.

Not run on Windows yet: only a stand-in for wsl.exe is tested.

Refs #925, #327, #721

* fix(remote): satisfy clippy in WSL output decoding

* style(run): format run types

* fix: regenerate bindings and drop untranslated WSL catalog entry

* test(i18n): list WSL as an untranslated product name

* fix(run): pick build wrappers and shell quoting by the execution host

A remote window runs commands on its Linux or macOS server, so a Windows
desktop no longer selects gradlew.bat, mvnw.cmd or Windows quoting for it.

* fix(welcome): open legacy WSL UNC recents and sessions through the distro

Recents and the restored session called the local openProject for a
\\wsl.localhost folder saved before WSL projects, which fails with OS
error 123. They now resolve it like the other entry points.

* fix(windows): keep WSL files out of remote project launches

path_launch tested the WSL share before is_dir, so a first-instance CLI
launch with a WSL file opened a remote project instead of LightEdit.

* fix(remote): run-command OS comes from the remote host, not an assumption

The server's OS was dropped after connect, so a restored session had none and
isWindows() assumed every remote host is Unix. Keep it on the connection and
the session, and resolve it through hostOs().
