Loach v1.4.0

What's new

• Reworked onboarding. Setup now sizes its model suggestion against your GPU's VRAM — or system RAM when there's no discrete GPU — and labels every option, so you know what you're in for before the download starts. The pull runs in a strip you can leave working while you carry on. A new tools step covers web fetch and the in-process utilities, opening on a recommended selection with All OFF / Recommended / All ON presets and a switch per tool — anything that reaches the network stays off until you turn it on.
• Better search. Search now looks inside message content, not just titles. Scope it with the picker or by typing an in: filter — in:chats, in:messages, in:spaces, in:snippets — and message hits keep a reserved block of their own so a common word can't crowd them out.
• LaTeX math in replies. $$…$$, $…$, \(…\), \[…\] and ```math fences typeset with KaTeX — no setting to hunt for. $ still works as a currency sign, so "it costs $5 and $10" stays prose. KaTeX ships inside the app and is read from disk only the first time a reply contains math.
• Auto-lock. Once an app lock is configured, Settings → Security can lock Loach after 1, 5, 15 or 30 minutes without typing, or the moment the window is minimized. Both are opt-in, and Cmd/Ctrl + Shift + L locks immediately from anywhere in the app.
• Storage breakdown. Settings → Data now shows what your chats, attachments and Spaces actually weigh on disk.
• Undo an archive. Archiving a chat offers an inline Undo, and a quiet Archived row appears in the sidebar whenever archived chats exist — so nothing looks gone for good.
• In-app updates for .deb and .rpm. Linux package installs now update in place like the AppImage does, downloading the signed package and elevating through pkexec. Installs from v1.2.3 or earlier still need one manual download from the releases page before in-app updates take over.

Fixes

• Correct arithmetic. The calculator tool moved to a new engine and now groups expressions the way every other language does — 100 / 5 * 2, 2 * 10 % 4 and 2^3^2 all come out right — and reads scientific notation like 6.022e23 instead of failing on it.
• Math no longer disturbs code. Formula detection leaves code blocks, currency and half-typed TeX alone; unparseable TeX shows its own source rather than flashing an error mid-stream.
• Legible in Light theme. Contrast failures across toasts, onboarding, code blocks and links are fixed.
• Reachable by keyboard. Every control has an accessible name and a visible focus ring.
• Fewer rough edges. Timezone-aware date differences, chat parameters that no longer go stale, no leaked streams on cancel, and a model picker that opens in front of the onboarding wizard instead of behind it.
• Dependency updates throughout, including a security fix for the PDF reader.
