* Sensitive word obfuscation for Antigravity requests.

*
|
|
* Obfuscates client tool names (OpenCode, Cursor, Claude Code, etc.) using
|
|
* zero-width joiners so Google's backend can't grep for them in request logs.
|
|
* Matching ZeroGravity's ZEROGRAVITY_SENSITIVE_WORDS and CLIProxyAPI's cloak system.
