v0.1.5

Added

• Scrolling session tabs. The F2 strip used to render only the chips that
  fit and silently drop the rest. It now renders a window over the tab list with
  ‹ / › edge markers that are clickable and participate in hit testing, and
  a mouse wheel over the strip row scrolls it. The window follows the active
  chip by default, so every activation brings its tab into view; an explicit
  scroll pins the window and steps from what the last frame actually painted.
  Reaching either end releases the pin.

Changed

• A session opened from the dashboard renders like any other session. The
  extra 1/2 [‹][›] [Dashboard] header band is gone, and with it the footer
  differences it justified: the overlay footer no longer prepends navigation
  hints, no longer suppresses the right-hand status line, and no longer
  re-points the shortcuts chip away from Ctrl+X. An attached session and a
  plain one now draw byte-identical frames.

Fixed

• Delete works on every session row. Tying deletion to TopLevel rows meant
  only active and idle sessions could be deleted; sessions the dashboard lists
  from disk (shown as Inactive) were refused. Both row kinds share the same
  confirm window and the same transcript deletion, so a roster row can now be
  deleted. Subagent rows stay refused, since they belong to their parent's
  transcript.
• Sessions no longer disappear from the dashboard. Two filters — one hiding
  local sessions with no conversation, one hiding untitled roster entries — made
  a session created and closed without a first message unreachable: it existed
  on disk but no row named it, so it could not be reopened, renamed or deleted.
  Both filters are removed. An untitled session is labelled
  New session #<id> and stays listed.
• Opening a session from the dashboard creates its tab. Three paths skipped
  tab registration: attaching assigned the view directly, switch_to_agent
  returned early before registering when the target was already the active
  view, and a load that started from an unbound placeholder refreshed a chip
  that did not exist yet. All three now register, and a background bind adds the
  chip without moving the active one.
