Fix Qwen3 Coder streaming tool calls lost when entire call arrives in a single delta (large stream_interval or speculative decoding bursts). Also register the lfm2 reasoning parser.

…livery

When stream_interval is large or speculative decoding bursts many tokens,
a single delta can deliver multiple tool call phases (header + opening brace +
params + closing brace) at once. The parser was returning early after each
phase, dropping intermediate content.

Also register the lfm2 reasoning parser.

Superseded — the single commit on this branch split cleanly into two better homes:

Nothing unique remains in this PR. Closing in favor of vllm-project#43074 and #5.
