lsrpc is local IPC (IDE ↔ language_server binary), not an upstream protocol.
cloudcode-pa.googleapis.com does not serve gRPC/lsrpc endpoints.
Restores antigravityRetryLoop + streamGenerateContent path which was working.
Removes antigravity_lsrpc.go (upstream caller) and lsrpc_test cmd.
Keeps lsrpc_handler.go (server side, receives IDE connections).
The test request was using maxOutputTokens: 1, which caused Google API to
generate only 1 token. When decoded, this single token produced "It" as the
response, making it look like an error.
Changed:
- Content: "." → "Test connection" (more meaningful prompt)
- MaxTokens: 1 → 10 (enough tokens to verify connection is working)
This fixes the issue where account test always showed "It" in the response,
which was actually just the truncated output from the single-token generation.
