Morse v0.24.0

The browser host updates itself in one click, and every list is now one tree.

New

• Update the browser host without leaving it. The footer's "Update available" notice is a button: it asks
  the host to install the latest release and relaunch, and the page reloads on the new build — no terminal, no
  re-running a command. It is off unless the host was started with MORSE_SELF_UPDATE=1, and the install never
  runs in the process it replaces: a detached helper waits for the old daemon to exit, installs, and starts it
  again. Refusals (not opted in, a caller that is not on loopback, an install that is not a writable
  npm-global) answer with a reason and the notice falls back to the command it already printed. morse update
  does the same from a terminal, and morse start now remembers its port so a restart lands on the same URL.
• A session chimes when its run finishes. The completion notice only ever spoke visually, and a reader who
  stepped away from the panel — the case it exists for — had nothing to hear. A synthesized two-note chime now
  follows the same away/always policy as the toast, with its own mute switch. The palette gains "Mute/Play a
  sound…" and "Send a test notification", the latter firing on demand so the channel can be checked without
  waiting for a run.
• Every repository under a project is in the git panel. A project can hold more than one repository — its
  own plus a nested submodule or checkout — and the panel only ever saw the one the session sat in. It now
  lists them all, each stage/commit/checkout/pull/push acting on the open repository, and the badges merge
  every repository's status. Sections expand in place, one at a time, the way VS Code's Source Control lists
  them.
• The Explorer and the session list share one tree. They were the same list drawn twice and had begun to
  drift. One component now renders both; the session list also nests a forked session under the session it
  was forked from.
• The prompt-template editor has a toolbar button. It was wired but reachable only by keyboard shortcut and
  the palette, so on the web it looked missing next to MCP and Git. It now sits beside them, lit while its tab
  is in front.
• A session in front comes back across a window reopen. The VS Code host advertised no workbench
  capability, so a reopened window started on an empty draft. It now saves and restores the session in front,
  the same behaviour the browser already had.
• Prompt-template argument fields grow to fit. They were single-line, so a pasted stack trace or paragraph
  hid all but the first line. Every field is now an auto-growing textarea — one row tall at first, growing to
  a cap before it scrolls — with Enter inserting a newline and Ctrl/Cmd+Enter sending.
• The annotation editor splits into Write and Preview tabs. The old overlay drew a live mirror of the
  markdown under a transparent textarea, and the two layers would not stay on one character grid — the prose
  slid out from under the caret. Source and rendering are now two surfaces, each with the whole box, and the
  caret and draft survive the round trip.

Fixed

• Stop asks before it ends a run. It sat beside Steer and Follow up, so a stray press killed the run
  outright. It now confirms, like compaction, and the question retracts itself when the run it is about ends.
• Compaction acts on the session its dialog was opened over. session/compact named no session, so a
  dialog opened on one conversation and a switch in between silently rewrote another's memory. The message
  now carries the pinned session, and a confirm against a closed session fails loudly instead of compacting
  the wrong conversation.
• The composer holds a prompt while the model and thinking levels settle. Switching models could send a
  prompt against the previous model's reasoning level, and a fast Enter could reach the agent before the model
  pick did. The mutating messages are now ordered, and Send stays disabled until the new levels are read.
• A prompt sent with a picked model no longer carries the previous model's level. While a model's levels
  load, the picker reports thinking off and no options, instead of showing the stale list.
• pi is found and started on Windows. Detection read only the extensions in PATHEXT, which a window
  opened from the Start Menu rarely inherits and which omits .ps1 on purpose — and a found pi.cmd still
  failed to launch, because CreateProcess cannot start a batch file. Resolution now returns a spawn plan:
  .exe/.com run directly, .cmd/.bat through a shell, a lone .ps1 through PowerShell.
• Morse activates when you grant trust. A first-time window opens untrusted, so the extension stayed
  disabled in Restricted Mode and the panel came up blank until a manual reload. It now declares its untrusted
  behaviour and starts when trust is granted.
• A session's editor tab closes when the session does. Closing or deleting a session from the sidebar used
  to leave its tab behind, and a tab whose session was deleted while the window was closed came back pinned to
  a conversation that no longer exists.
• The status bar stops counting tabs a host cannot close. In VS Code the editor's own tabs are the strip, so
  the sidebar's tab count listed conversations that were not open and could not be closed by hand. The count is
  hidden where there is no Morse tab strip, and the strip reconciles against the host's session list.
• The browser host's caches are bounded. Three structures grew for the host's whole lifetime: the
  workspace index kept a listing for every project ever browsed (now an 8-entry LRU), and an LSP client kept
  every document ever opened and its diagnostics (now a 256-entry LRU that closes evicted files). A diagnostics
  wait also now ends when the server dies, instead of leaving the preview spinning until its timeout.
• A retired session frees its transcript. A session the registry evicted on its own left its whole
  conversation and tool index in the transcript store for the host's lifetime. Eviction, close and delete now
  all release it.
• The model chooser and the thinking panel no longer overlap. Opening the chooser left the thinking panel
  up, and the two dropdowns stacked. They now share one positioning context and close each other.
• The palette's key hints stay readable at every width. The hint bar stacked only below 520px, but the card
  is already too narrow for one row well before that, so the source prefixes between 520px and 672px were
  ellipsised away. The breakpoint now tracks the card.
• A deep tree stays readable. Each level cost two columns, so a folder five deep was a wall of bars. A level
  is now one guide line, with the tree pulled left and the caret, gutter and row padding brought in with it.
• A nested row steps in past its parent's corner. A child drew its corner in its parent's column, so the two
  rows read as one label rather than a parent and its child.
• The New session blurb is spaced from its search field. The projects screen dropped the sub-heading
  straight onto the input.
• The redundant Attach Selection button is gone from the toolbar. The composer already offered it; the
  command stays in the palette for keyboard use.

Improved

• morse start reuses the workspace and port it had before. A restart — including the one the self-update
  runs — comes back on the same URL, so the browser tab that is reloading finds it there. A remembered port
  taken while Morse was down falls back to a free one instead of refusing to start.
