fix(presidio): stream SSE output incrementally instead of buffering the whole response (#31503)
The Presidio streaming post-call hooks (_stream_apply_output_masking for
apply_to_output and _stream_pii_unmasking for output_parse_pii) collected every
upstream chunk, reassembled the full completion with stream_chunk_builder at
end-of-stream, ran Presidio over it, then emitted one reconstructed SSE chunk.
Time-to-first-token collapsed to the total generation time and token-by-token
streaming was lost whenever Presidio output handling was enabled. With the
default presidio_filter_scope both, an apply_to_output masking instance is always
created, so even the unmask configuration buffered the stream.

Both paths now transform and forward chunks as they arrive. The unmask path
replaces placeholder tokens per chunk, holding back only the trailing run that
could still grow into a token so a placeholder split across SSE chunks
(<PER + SON_1>) is still rewritten atomically. The mask path emits a prefix only
when masking it in isolation matches the corresponding prefix of masking the
whole buffer, with a lookahead margin still buffered past the cut, so an entity
straddling the cut is detected and held until complete; past
_PRESIDIO_STREAM_MAX_BUFFER the run is bounded without splitting an entity.
Tool-call and legacy function-call argument fragments are accumulated per choice
and transformed once the choice closes, content is buffered independently per
choice index for correct n>1 streaming, raw Anthropic SSE bytes and /v1/responses
events pass through with any held content flushed first so events never reorder,
and a masking error redacts only the affected chunk (fail closed, keeping
finish_reason) while the stream continues.
