Summary

Bundles Nimbalyst (a visual workspace for building with Codex, Claude Code, and more) into the coder-xfce-vnc variant, mirroring the existing Lens/Claude install pattern, and moves the Lens, Claude Desktop, and Nimbalyst menu entries into the XFCE Development category.

Nimbalyst (AppImage)

Nimbalyst ships only as a Linux AppImage, which would self-mount via FUSE — impossible in the unprivileged target pod (FUSE's mount needs CAP_SYS_ADMIN, the same capability that disables the Chromium sandbox). The build therefore:

Pulls the always-latest release via the releases/latest redirect (no version pin, same intent as the JetBrains Toolbox block).
Extracts it with --appimage-extract (no FUSE, no /dev/fuse) to /opt/nimbalyst.
chmod -R a+rX the tree, since the AppImage's squashfs preserves 0700 dirs that a root-owned bundle would hide from the coder user (caught during testing — would otherwise ship a broken launcher).
Routes launches through scripts/nimbalyst-wrapper.sh → /usr/local/bin/nimbalyst, applying ELECTRON_DISABLE_SANDBOX=1, --disable-dev-shm-usage, and APPDIR=/opt/nimbalyst (the bundled AppRun's AppDir auto-detection misfires when the first arg is a flag rather than a file).
Generates the desktop entry from the bundle's own entry, asserted via grep like the Lens/Claude entries.

Development category

The Lens and Claude sed-generated entries and the new Nimbalyst entry now normalise Categories=Development (was Network / Office / Utility), so all three sit next to the other dev tooling in the XFCE menu.

Docs

README.md: features list, the Electron & Chromium-based apps section (with the AppImage/extract rationale), and the persisted-state table (~/.config/@nimbalyst).

Verification

Validated end-to-end in a live coder-xfce-vnc workspace by replicating the exact image install (/opt/nimbalyst root-owned + a+rX, wrapper, desktop entry) and launching through /usr/local/bin/nimbalyst as the coder user — Nimbalyst's window maps and the app boots cleanly with none of the FUSE / sandbox / shm failure modes.

Bundle Nimbalyst (a visual workspace for building with Codex, Claude Code,
and more) into the coder-xfce-vnc variant, mirroring the Lens/Claude pattern.

Nimbalyst ships only as a Linux AppImage, which would self-mount via FUSE —
impossible in the unprivileged target pod (FUSE's mount needs CAP_SYS_ADMIN,
the same capability that disables the Chromium sandbox). So the build extracts
it with --appimage-extract (no FUSE, no /dev/fuse) to /opt/nimbalyst, pulling
the always-latest release via the releases/latest redirect, and routes every
launch through scripts/nimbalyst-wrapper.sh (/usr/local/bin/nimbalyst). The
wrapper applies the two Electron fixes (ELECTRON_DISABLE_SANDBOX=1,
--disable-dev-shm-usage) plus APPDIR=/opt/nimbalyst, because the bundled
AppRun's AppDir auto-detection misfires when the first arg is a flag. A
chmod -R a+rX makes the root-owned 0700 squashfs tree traversable by the
coder user, and a sed-derived desktop entry is asserted via grep like the
Lens/Claude entries.

Also normalise the Lens, Claude Desktop, and Nimbalyst desktop entries to
Categories=Development so all three land in the XFCE Development menu (was
Network / Office / Utility) next to the other dev tooling.

README updated: features list, the Electron & Chromium-based apps section
(with the AppImage/extract rationale), and the persisted-state table
(~/.config/@nimbalyst).
