Magic Context Dashboard config embedding tester

[draxxris]

bunx doctor now properly validates the embedding config (per #29) but the dashboard GUI does not function properly:

Fixed in dashboard-v0.3.1.

The embedding endpoint "Test" button in the Memory configuration panel now matches doctor's classification exactly:

• {env:VAR} / {file:path} substitution before probing
• Body inspection on 2xx responses (catches OpenRouter's /embeddings returning chat-completion bodies)
• Auth-vs-other HTTP error distinction
• 404/405 → "wrong URL or no embeddings API" guidance
• New unresolved_token outcome for the common macOS case where EMBED_API_KEY is in your shell rc file but the dashboard was launched from Finder/Dock (different env inheritance from launchd)

Users running doctor and the dashboard now see the same text for every failure mode.

Upgrade via the in-app Check for Updates... (app menu on macOS, or via the tray icon), or download from https://github.com/cortexkit/opencode-magic-context/releases/tag/dashboard-v0.3.1

Please reopen if the tester still misbehaves on 0.3.1.
