fix(parsers): retain independent facts and boundary identity

Share bounded ELF section-name decoding across native and note readers; retain read-only ranges and coverage reasons when names are unknown. Preserve ELF symbol-version bytes, dyld-bound method uncertainty, partial gRPC-Web trailers, and per-parent model identity checks. Compare GPU signatures as bytes and require a PTX module header. Share selected-path errno classification across EVM and BEAM.

Validation: 397 shared-parser tests passed (one existing skip), 5 MCP schema tests passed, 14 EVM error-mapping tests passed, and 23 protobuf CLI/MCP matrix cases passed across focused runs. Build, typecheck/lint, docs, formatting, and 2134-file discovery passed. Full EVM provider workflow remains locally unverified on Darwin arm64; format controls are synthetic.
