Subject: [PATCH] fix(credentials): cache credentials after prompt and clear
 cookies on logout

Problem: \`prompt_and_login\` never called \`cache.set_credentials\` on
success, so the fast path in \`M.login\` never triggered on subsequent
calls. \`M.logout\` only cleared the plugin credentials cache, leaving
browser cookie files on disk.

Solution: call \`cache.set_credentials\` after a successful
\`prompt_and_login\`. Add \`COOKIE_FILE\` constant and update \`M.logout\`
to remove the platform's entry from the shared cookie file.
