yucheng-berri b21e8ea009 fix(otel): repair Arize OTel v2 regressions from #43698 (linear fit, metadata slot, repr tool args) (#44488)
* fix(otel): keep Arize OTel v2 regressions in check — O(n) fit, metadata slot, repr tool args

Three regressions from #43698's OpenInference tool-call/metadata emission:

1. Metadata evicted indexed message attributes: the new `metadata` key
   competed for the 128-attribute span budget, and the fit sheds whole
   message groups BEFORE `span.set_attribute`, so the SDK's dropped
   counter stayed 0 — an invisible eviction (live A/B: input-message
   attributes 86 -> 84). Two-part fix: the fit pins `metadata` behind
   every message group (it sheds only once all indexed messages are
   gone), and the span budget no longer charges pre-set attributes the
   mappers overwrite in place — a boundary-opened LLM span already
   carries keys like `gen_ai.request.model`, so the old accounting
   reserved slots the fit could never spend. Live: 86 input-message
   attributes with the metadata attribute riding alongside.

2. Quadratic shed on long prompts: `_message_shed_groups` rescanned the
   full group map once per message (measured on a real acompletion:
   0.032/0.128/0.478/1.910s at 1000/2000/4000/8000 messages vs
   0.007/0.010/0.022/0.029s at base). Index the tool-call groups once by
   (family, message index): the fit is linear again (0.008/0.007/0.014/
   0.031s, same rig).

3. Malformed Python tool arguments lost the whole span: provider
   adapters and `model_construct` responses hand over raw objects, and
   `json.dumps` raises on tuple-keyed dicts (TypeError) and cycles
   (ValueError) before the span is exported. Serialize with a repr
   fallback; both cases now export with a readable arguments attribute.

The attribute budget change affects every boundary-opened LLM-call span
(strictly more attributes retained, never fewer); the mapper changes
only touch the OpenInference vocabulary.

* refactor(otel): build the tool-call group index in one shot

Review follow-up: the dict.setdefault/append seeding in
_tool_call_groups_by_message violated the no-mutation coding convention
(AGENTS.md: build values in one shot with comprehensions or generators
wrapped in tuple()/MappingProxyType()). Rebuild it as a sorted groupby
comprehension; randomized parity harness confirms the shed order is
byte-identical to the seeded version (400 trials).

Also pin the overflow corner Greptile asked about: a pre-set
indexed-message key the fit sheds keeps its earlier value in place, so
the span total can never exceed the SDK limit (new emitter test).

* fix(otel): key the groupby with an explicit tuple to keep basedpyright at budget

The slice-keyed groupby (group[:2]) widened the key to tuple[str | int],
adding one reportGeneralTypeIssues over the codebase ceiling. Key by the
explicit (family, message index) pair instead; shed order unchanged
(300-trial randomized parity harness).

* fix(otel): read pre-set span keys through a helper typed for both runtime shapes

The SDK annotates ReadableSpan.attributes as a Mapping, but an ended span
hands back a tuple of pairs, so the inline isinstance branch narrowed to
Never and pushed reportGeneralTypeIssues one over the codebase ceiling.
Extract _carried_keys with the runtime union declared on the parameter;
behavior unchanged.
