Note

Add team account name refresh to fetch and display ChatGPT account display names

• Adds a new account_name field to AccountRecord and a separate api.account config toggle alongside api.usage, with backfill logic for existing registries that only have one flag.
• Introduces src/account_api.zig to fetch account metadata from the ChatGPT accounts/check endpoint, and src/account_name_refresh.zig for file-based locking and candidate selection for background refresh.
• Refreshes account names after login, import, switch, and list operations, and adds a periodic background refresh in the daemon cycle with per-account cooldown tracking.
• Updates display label logic so grouped accounts show alias (account_name) or email / alias formats, and account search now matches against account_name.
• Moves cross-platform HTTP GET logic into src/chatgpt_http.zig, replacing the per-module curl/PowerShell implementations in src/usage_api.zig.
• Risk: enabling api enable now toggles both api.usage and api.account simultaneously; previously only usage was affected.
