v1.4.0

XeFM 1.4.0

• Six more archive formats open in place, and 7z can now be created. RAR,
  ISO, CAB, cpio, RPM and Zstandard-compressed tar join zip and tar: cursor on
  the file, Enter, and you are browsing it. Copying a member out streams it
  instead of reading the whole archive into memory, so a single file comes out
  of a large archive without the wait. Windows builds now carry libarchive
  themselves, so the formats are there out of the box rather than only where a
  system library happened to be installed.
• A surface's search and sort options open on one key. They used to take a
  key each; now one key opens the options for what you are looking at, every
  option is a switch you can click as well as type, and the band across the
  bottom of every modal says what the keys in front of you do — including what
  Enter actually does, which in the search dialogs is feed the results to the
  pane rather than open a file.
• Extract acts on what you selected. With files marked, extraction used to
  follow the cursor instead of the marks; it now extracts the selection, and
  falls back to the cursor only when nothing is marked.

Also: --ui-watchdog logs the stack the UI thread was stuck in whenever the app
stops repainting for longer than a moment — a developer diagnostic, off unless
asked for, aimed at the freezes that were previously only reportable as "it
froze". Help lists the archive formats this build can actually read, and says
correctly what stops an encrypted 7z from opening. The suite runs on Linux in
Docker against both libcs, with targets to drive the TUI there by hand. Key
bindings documentation now names the keys that exist.
