_on_toggle_editing() seeded self.combined from default_combined() on first
activation, which reads the stale per-profile JSONs for all 3 profiles
instead of the current versapad_config_all.json. Writing to board while
only editing one profile silently reverted the other two. Now prefers
loading the current combined file, falling back to defaults only if it
doesn't exist.
Also documents the READ_STATUS polling change and the jappel PR workflow
constraint in AGENTS.md.
AGENTS.md now follows the mandated section structure (Project Goal,
Aktuell unterstützte Architektur, Kritische Domänenregeln,
Existing-Codebase-Regel, Implementierungsdisziplin, Naming, Deferred
Work, Dokumentation und Verifikation) instead of an organically grown
set of headings. Folds in all prior technical notes (protocol
validation, network-drive build/runtime gotchas, threading rules)
under the appropriate section, and fixes a stale "no tray icon yet"
line that no longer matched the code. README gets an explicit honest
status paragraph (what's tested, what's not: no automated tests, no
prebuilt exe download, hardcoded paths).
No docs/ tree: project has no database or persistent multi-user
service, so the full doc structure isn't warranted per the standard.
Minimizing or closing hides the window instead of leaving a taskbar
entry; only "Beenden" in the tray right-click menu really exits. Tray
callbacks route through a queue instead of touching Tk directly from
pystray's thread (same pattern as the earlier serial-thread fix).
Also fixes the build script: PyInstaller failed on the network share
while copying Tcl/Tk tzdata (path-length issue), so building now
happens in a local temp copy instead of directly on Z:.
Adds an info button that explains the MCP server's available tools.
Avoids the cmd.exe flash from double-clicking run_desktop.bat and
gives a proper double-click .exe like VersaGUI.exe. Must be deployed
locally (%LOCALAPPDATA%) -- Windows silently refuses to load the
_internal DLLs when the .exe sits on the Z: network share, no error
shown. build_and_deploy.ps1 handles build + local copy in one step.
