Revoke the old grant after storeToken succeeds.
Lines 164-175 defer revocation until performOAuthFlow completes. If storeToken succeeds at Line 124 and fetchUserInfo or setAuth then throws, this block does not run. The replacement token remains stored, but the old refresh token remains valid.
Move revocation into the post-store success path, or use a finally that runs only after successful storage. Add a regression test for a user-info or config-write failure after storage.

Summary
Follow-up to #418, which could fail to revoke a session while still reporting success.
revokeTokennow returns its outcome instead of void, checks the response status so a permanent 4xx stops looking like success, and resolves the OAuth config inside its try block so a malformedCLERK_OAUTH_BASE_URLno longer aborts sign-out beforeclearAuthruns. Logout and re-auth warn on failure instead of printing an unconditional success, and logout flagsCLERK_PLATFORM_API_KEYwhen set.The outgoing session is now read inside the OAuth flow, just before the token exchange overwrites it, rather than before the browser flow and gated on a network probe that swallows its errors. That gate could orphan a live grant; the earlier placement also let a concurrent refresh rotate the token away, which makes revocation a silent no-op. The new placement closes the first and shrinks the second to one token request.
Docs corrected: revocation ends the current environment's grant and its refresh token, but the access token is a JWT the server refuses to revoke, valid until it expires.
