v0.4.2

Changed

• Review reads two sources, not three, and the statusline counts git. "This conversation" is
  gone. It was built on OpenCode's session.diff, which returns an empty list for a session whose
  own snapshots plainly differ — checked against three baselines, with the snapshot trees diffed by
  hand to confirm the changes were really there. A mode that cannot answer is worse than one that is
  missing, so it has been removed along with the dead FileChange.marked it was reserved for.
  [b] now toggles uncommitted and branch.

  The statusline's session.diff segment rested on the same feed and made the same promise. It is
  now git.diff and reads git diff --shortstat HEAD — what is uncommitted, a number you can check
  by running the command yourself. The old name still resolves, the command runs only when a line
  actually carries the segment, and a line without it spawns nothing.

Fixed

• /cockpit-update no longer promises an update it cannot make. It cleared the cached copy and
  told you to restart — but if your config pins opencode-cockpit@0.4.1, the next start reinstalls
  0.4.1 and the version never moves. It now reads both plugin lists (opencode.json and
  tui.json), and when a pin is in the way it says which entry to edit instead of clearing a cache
  for nothing. A path install and a tag are not pins, so neither is treated as one.

• The handover tells the agent what it needs before it asks. The submit message now names the
  files the comments are in, so the first move is not a tool call spent finding out where the work
  is; says plainly that resolving is refused while a file still reads as it did, which is what
  review_reply actually does; and draws a boundary — these comments, no unrelated work, no
  commits, and say so in the reply when a comment turns out to be the tip of something bigger.

• The panel no longer fails in silence. The change store set a notice in four places — "no
  conversation open", every git error, "file too large" — and nothing ever read it, so each of those
  reached the screen as an empty pane with no explanation. It is now shown in the footer, and the
  empty state names the source it is empty for and points at the key that changes it.

• [s] says how much there is to submit, and says the right thing when there is nothing. The key
  carries a live count and dims at zero, and the three ways to have nothing to hand over — no
  comments yet, all answered, all outdated — now read differently instead of all claiming every
  comment had been answered. Submit also counts outdated comments before offering, so the number it
  offers is the number it sends.
