Спампаваць agentty 0.9.52

Added
- ^U reads thinking in full (#123). On an empty composer it opens the
newest thinking block over the screen; ←/→ go to older ones, Esc lists
them all, ^U closes. Collapsed blocks say ⋯ N lines above · ^U to read,
and the palette has "Read thinking". A live retrieved-context card still
takes ^U first.
Changed
- The ^O and ^U viewers don't move under you. On the newest entry while
it runs, scrolled to the bottom, you follow new tools or thinking blocks.
Anywhere else you stay put and new ones show as ↑ N new; t goes to
the newest.
- Text arriving in those viewers types in with the transcript's
typewriter and pacing. The Motion setting turns it off the same way.
Fixed
- Collapsed thinking counts its hidden lines right. Long blocks said
"24 lines above" whatever their length.
- -m picks the model the TUI opens on. It was saved but the
provider's saved model won at startup.
- Reasoning settings take effect on the turn being written, the
"Reasoned · Ns" timer starts when thinking starts and stops on errors,
Hidden no longer fetches a summary it throws away, and Haiku/Sonnet 4.5
can think again.
- Alt+←/→ in threads includes threads made this session.
