serving_chat:
- Tolerate a malformed historical tool_call `arguments` string (a valid JSON
document followed by trailing content) instead of 400-ing the whole
multi-turn request: salvage the leading JSON document via raw_decode, else
keep the raw string. (A 112-message tool-history request was rejected with
orjson "unexpected content after document".)
- Catch TypeError (not only jinja2.TemplateError) from the chat-template
render so a `tojson` filter on a Jinja Undefined becomes a clean 400 instead
of a 500 (upstream #20700 / 5e9bd21979).
reasoning_parser:
- Strip only LEADING think-start marker tokens; a global replace would delete a
`<think>` token that legitimately appears inside reasoning content. Preserve
model-generated whitespace in reasoning/normal text (drop .strip()/.rstrip())
(upstream #24251 / dac78768f0).
- Add Glm45 detector tests: leading-only strip, token-inside-content preserved,
repeated leading markers, streaming trailing whitespace.
