✨ New features

Terminal performance overhaul

Heavy output (long boot logs, big file dumps) now renders much more smoothly — drawing was
reworked to stop re-creating fonts and brushes on every frame.
Scroll-back history storage was rebuilt so the terminal stays fast no matter how much output
has accumulated; previously it got slower and slower once the history buffer filled up.

Full-screen apps (vim / htop) behave like a real terminal

The mouse wheel now scrolls inside full-screen tools like vim and htop instead of doing nothing.
Tools that ask the terminal "where is the cursor?" now get an answer — fixes full-screen apps
that could hang on startup or draw at the wrong position.

Connection status you can actually see

When an SSH connection drops or hits an error, a message now appears right in the tab —
no more sessions that silently stop responding.
When the local shell exits (e.g. you type exit), the tab shows
[ETTerms] shell process exited instead of just going dead.

Faster PDU status (GUI and AI)

Outlet polling now bundles all 12 ports into a few SNMP requests instead of 36 separate ones —
the Status page refreshes faster, and an unreachable PDU no longer stalls the poll for minutes.
The AI pdu_status tool gets the same speed-up.

Garbled Chinese / non-English text

Fixed: multi-byte characters could occasionally turn into � garbage when text was split
across data chunks — this affected TTL script wait matching, what the AI reads over the
serial bridge, and saved session log files. All three now decode correctly.

Scrolling

Fixed: while you were scrolled back reading history, any new output yanked the view down to
the bottom. The view now stays where you are and only follows when you're already at the bottom.

Resource & stability

Fixed small memory and handle leaks when opening and closing many local shell tabs over a
long session.
Fixed: typing into an SSH session after the connection died could crash the window — it now
just prints a short "write failed" note in the tab.

Two builds are produced:
