Release v0.0.6

Toasts now render three content rows with word-wrapped bodies. The
in-toast "Ctrl-N · N more" hint is replaced by a short
"Ctrl-N · dismiss" entry on the status strip that only appears
while a notification is live.

The box stops flickering while the focused child repaints its TUI:
the overlay is stitched onto the per-chunk PTY write under outMu
and bracketed by DECSET 2026 so supporting terminals buffer the
child's redraw and the box paint into a single frame.

 ## [Unreleased]
 
+## [0.0.6] - 2026-05-15
+
+### Changed
+- Toast notifications now reserve three content rows and word-wrap
+  the message body inside the box, replacing the previous
+  single-line+ellipsis layout. The `Ctrl-N · N more` inline hint is
+  gone; instead the host status strip surfaces a `Ctrl-N · dismiss`
+  hint, shown only while a notification is on screen so the chord
+  doesn't advertise itself when it has nothing to dismiss.
+
+### Fixed
+- Auto-summary no longer fails immediately with `codex summarizer:
+  error: unexpected argument '--ask-for-approval' found`. The codex
+  CLI dropped that flag; we now rely on `--sandbox read-only` (which
+  already implies no approvals) instead of passing it.
+- Toast box no longer flickers / half-erases while the focused
+  child (claude, codex, opencode, etc.) repaints its TUI. The
+  overlay is now stitched onto the end of the per-chunk PTY write
+  under `outMu`, and wrapped in DECSET 2026 (synchronized output)
+  brackets so terminals that support it batch the child's redraw +
+  the box paint into a single frame instead of racing cell-by-cell.
+
+## [0.0.5] - 2026-05-15
+
+### Changed
+- Replaced the single-slot status-line "flash" with a stackable toast
+  surface anchored at the top-right of the focused pane. `flashError`,
+  `flashTransient`, and MCP `request_human_attention` now push onto
+  the toast stack (cap 5, oldest drops). Toasts persist until
+  dismissed with `Ctrl-N`, or cleared via the new
+  "Clear notifications" palette command. The status line no longer
+  shows the `[!]` prefix.
+- `Ctrl-N` is consumed by the host only when there is a toast to
+  dismiss; an empty stack lets `Ctrl-N` pass through to the focused
+  child so readline / nano / emacs / opencode keep their bindings.
+- Command palette is calmer when something is focused. Focused-section
+  rows now read as bare verbs (`Rename`, `Close`, `Stop`, `Restart`,
+  `Delete`, `Edit`) instead of repeating the focused name (`Close
+  agent: codex`); the title bar's `on: codex` / `pad: notes.md`
+  carries the subject. Fuzzy queries still match the dropped context
+  through the row hint (e.g. typing `close codex` still finds the
+  Close row).
+- Dashed `── Focused ──` / `── Open ──` / `── Spawn ──` section
+  banners are gone. Sections are separated by a single blank spacer
+  row, so the action labels themselves carry the visual weight.
+- The Open section no longer lists a `Switch to <current>` row for
+  the pane you're already focused on.

-The close action in the command palette should just be "Close current agent" rather than "Close codex"
-Same with the other "focused" parts. It seems a bit clunky right now. "Close current agent"
-In general I think while the feature set has grown, the actual refinement of it isn't great, it feels a bit cluttered.
