Files beside the thread, model thinking, and community fixes

New

Files open in the right sidebar. Opening a file from a link, an @-mention, Changes, Search, Files or an attachment now opens it in an Open files tab in the inspector. The conversation stays visible.
Thinking text. While an agent reasons, a folded Thinking block above its answer shows the text (Claude, Codex, ACP harnesses, Pi, Muse). (#197)
New harnesses: ZCode (#165) and Hermes Agent (#177).
Environment variables for harnesses, globally and per provider (#157).
Headless server mode with pandacode serve (#161).
Cloud agents in Docker containers and on DigitalOcean, Vultr, Hetzner and RunPod over SSH (#173).
Netlify deploy target (#149).
Usage: DeepSeek balance in the usage panel (#175), measured per-task token usage beside the saver estimate (#187), and an offer to tighten the token saver as context fills (#183).
Push notifications on the phone for approvals and finished tasks, off by default (#191).

The Settled section in the sidebar now uses the sidebar's own color instead of a darker block.
Kimi Code K3.x models offer Low, High and Max thinking levels instead of only On (#141).
Reasoning efforts for every DeepSeek model (#198, #196), and OpenCode efforts listed from least to most (#193).
iOS Simulator taps work when a device profile has no screen size, such as iPhone 18 Pro on iOS 27 (#145).
Linux: the AppImage no longer freezes on launch on systems with the COLRv1 emoji font (#179).
Pi models are found from unquoted Windows launchers (#146).
Team setup shows a busy state right away (#151); skills import menus follow the theme (#150); Kilo Code and Oh My Pi logos (#152); update-cache edge test (#98).

The iOS 27 simulator fix and the Linux font fix could not be tested on those exact systems before release.
OpenCode's "Default" model shows no effort control, because OpenCode reports its default model's efforts only inside a session.

macOS (Apple silicon): open PandaCode-macOS-arm64.dmg and drag PandaCode to Applications. This build is signed and notarized, so macOS opens it without a warning.
macOS (Intel): the same, with PandaCode-macOS-x64.dmg.
Windows x64: run PandaCode-Windows-x64-setup.exe. If SmartScreen warns about an unknown publisher, choose More info > Run anyway.
Windows arm64: run PandaCode-Windows-arm64-setup.exe (same SmartScreen step).
Linux x64: chmod +x PandaCode-Linux-x86_64.AppImage and run it.
Linux arm64: chmod +x PandaCode-Linux-aarch64.AppImage and run it.
Any of the above, from a terminal: npx pandacode downloads, verifies and installs the right build, and signs it locally on macOS, so no Gatekeeper warning appears.

Each file has a .sha256 checksum beside it. Installed copies update themselves from this page. Build from source: see CONTRIBUTING.md.
