Local Dev d07f2ff757 Theseus 0.3.126: Claude connector detects Microsoft Store install of Claude Desktop
The Store install of Claude Desktop lives under
%LOCALAPPDATA%\Packages\Claude_<publisher-id>\, and its "AppData\Roaming"
is virtualised to LocalCache\Roaming inside that package. The classic
%APPDATA%\Claude\ folder is never read by the Store app, so a
claude_desktop_config.json dropped there is invisible to it; Theseus's
old existence check against path.dirname of that classic path was both
false-negative (nothing in classic, Store present) and false-positive
(empty classic folder left over, Store the real install) — the user saw
"Not installed on this computer" with Claude Desktop clearly running.

desktopConfigPath now looks for a Claude_<id> package first and uses
its LocalCache\Roaming\Claude path when present; otherwise it falls back
to the classic path. Added a desktopInstalled() helper that treats any
of: the config dir, a Store package, %LOCALAPPDATA%\AnthropicClaude,
%LOCALAPPDATA%\Programs\Claude, or Program Files\Claude as proof of an
install. register() mkdirSyncs the chosen path so the Store case
succeeds on first write.

Claude connector

Built-in Theseus extension: a local MCP server through which Claude Code or Claude Desktop works in the user's tabs. Setup and safety model are in the Theseus README ("Claude connector (MCP)") and DESIGN-claude-connector.md.

Stored in <userData>/extensions-data/claude-connector.json (token, port, switches, approved origins, upload folders) and <userData>/extensions-data/claude-connector/ (endpoint.json while listening, actions.log).

Needs the host's tab-control capability, which only built-in add-ons get. Turning any extension on or off restarts every add-on, this one included, which ends the connected clients' sessions. A client that does not start a new session by itself reconnects from its MCP menu (/mcp in Claude Code).
