Ettore Di Giacinto e1a6010874 fix(streaming): deduplicate tool call emissions during streaming (#9292)
The Go-side incremental JSON parser was emitting the same tool call on
every streaming token because it lacked the len > lastEmittedCount guard
that the XML parser had. On top of that, the post-streaming default:
case re-emitted all tool calls from index 0, duplicating everything.

This produced duplicate delta.tool_calls events causing clients to
accumulate arguments as "{args}{args}" — invalid JSON.

Fixes:
- JSON incremental parser: add len(jsonResults) > lastEmittedCount guard
  and loop from lastEmittedCount (matching the XML parser pattern)
- Post-streaming default: case: skip i < lastEmittedCount entries that
  were already emitted during streaming
- JSON parser: use blocking channel send (matching XML parser behavior)
