v0.4.2

Changed

• Sessions in throwaway workspaces are marked as scratch instead of each counting as a project of its own: a T3 Code
  thread started without a project (…/t3/scratch/<date>-<title>-<hash>, named by its title) and a folder in a
  temporary folder (/tmp, /var/tmp, macOS's /var/folders/…/T, $TMPDIR; Claude Code's scratchpads
  there are just scratch). A git repository cloned into a temporary folder keeps its name.
• overshare archive files them all in one _scratch folder, with scratch: true in the frontmatter. The next run
  moves files already archived elsewhere into it.

Fixed

• overshare archive gave sessions whose ids share a name before their UUID (a pi session started by a tool, such
  as <name>-<uuid>) the same short id, so they overwrote one file. The short id now comes from the UUID wherever it
  is in the id, and an id without one that is longer than eight characters is hashed. A file an older version wrote
  for such sessions (named with the first eight characters, which they shared) is left as it is; delete it by hand.
