v0.8.0

Claudible v0.8.0

A hardening pass with one new behavior: renaming a project renames its
GitHub repo (your transcripts are never touched).

Also: the sidebar tells the truth (no stale rail, no phantom sessions, no
flicker, the active tab always has a row); synced changes and invited
projects land without a nudge; a failed clone can no longer delete a folder
that was already there; and the Linux terminal keeps its pty fallback.
