0.49 topru

[zhoucai-pingcap]

Summary

Merges 0.49-topru into 0.49, bringing TopRU-related protocol/parser updates, continuous profiling (jeprof) improvements for native heap profiles, and small CI/build and sink adjustments.

Motivation

• Align TopSQL upstream parsing and protobuf definitions with the current TiDB/TopRU expectations (tidb.proto and generated/parser code).
• Extend native jeprof tooling to support heap_v2 profiles and fix earlier native jeprof issues.
• Simplify release/CI matrix by dropping ARM Vector builds first (see CI/Makefile changes), and keep Docker release scripts in sync.

Changes

TopSQL / TopRU (upstream)

• Update proto/tidb.proto and corresponding proto/parser usage in topsql and topsql_v2 (src/sources/topsql/upstream/tidb/*, src/sources/topsql_v2/upstream/tidb/*).
• Refactor TopSQL v2 TiDB parser for consistency with the updated proto and clearer handling of record types (including component vs legacy type naming where applicable).

Conprof / jeprof (native)

• src/sources/conprof/tools/jeprof_native.rs: native jeprof support for heap_v2, plus fixes for native jeprof behavior.

Sinks (minor)

• topsql_data_deltalake and topsql_meta_deltalake processors: small aligned updates (4 lines each in current diff).

CI / build / release

• .github/workflows/build_image.yml: workflow updates (including ARM-related removal per commit intent).
• Makefile, scripts/release-docker.sh: aligned build/release adjustments.

Commits (high level)

Commit	Description
7ce3e3e	Fix TopRU / TiDB proto and TopSQL(v2) parser alignment
387215d	Change record field to component where appropriate
6aaf6af	Fix native jeprof issue
8667b91	Remove ARM vector build first (CI/Makefile)
ddbe3a1	Native jeprof: heap_v2 support

Testing

• cargo test / project make test (or CI green on this branch)
• Smoke: TopSQL v2 pipeline against TiDB with TopRU-enabled workloads (if applicable)
• Conprof: ingest heap_v2 jeprof sample and verify native conversion path

Risk / rollout notes

• Proto/parser changes may affect compatibility with specific TiDB builds; confirm the target cluster’s TopSQL gRPC/proto version matches this branch.
• CI/build matrix change (ARM Vector removed): confirm release and image consumers no longer rely on those artifacts.
