…s-trace-filtering
This reverts commit 6e5f6bf.
… add missing license header The dedup() call added to send_trace_chunks_inner was reversing VecMap key order unconditionally, changing the attribute ordering in V1 msgpack output and causing snapshot mismatch. The V1 encoder already calls defensive_dedup() internally; the extra dedup is unnecessary. Also adds missing Apache 2.0 license header to test_trace_filters.rs.
New test agent no longer propagates _dd.p.tid and _dd.p.dm from chunk level to child spans.

What does this PR do?
Implements the CSS trace-level filtering mechanism, that is applied before stats computation.
Motivation
It's un unmet requirement from the spec.
Additional Notes
Please Ctrl+FFIXMEwhen reviewing, I let some questions in the code that I'd like answers for before mergingTODO:
Wont do
advanced resource normalization (sql, redis etc...).No other implementation does that100% normalization edge cases (empty service field + non-normalized name + filter depending on that)Too specific edge case. Ignoring it for nowcheck on meta_struct tooNot in the specAPMSP-2763
