Run the Rust dynamic and static test matrix against four chdb-core CI artifacts from main commit dec391dcdf788cbecede338a0f305b399d8495e1. Add a static host-backtrace/panic regression for #53 and support the new native archive layouts. This is pre-release validation only; it does not publish a crate or change the engine pin.

Note

Add Rust CI workflow to validate chdb-core main artifacts

• Adds a pull-request workflow that verifies chdb-core main artifacts by pinned SHA, downloads them, and runs dynamic and static Rust builds and tests across a four-OS/arch matrix (Linux, macOS, plus durable and durable-s3 coverage) in core-main-artifact-check.yml
• Rewrites bundled_runtime_symbols_cannot_bind_host to accept the supported archive layouts: prelinked Linux archives and macOS archives with renamed private runtime symbols, while still rejecting unknown layouts
• Adds a static-only host_backtrace_and_panic test case that disables engine signal handlers, forces a failing query, and checks the host Rust backtrace and a catchable panic in runtime_faces.rs
• Behavioral Change: the workflow job fails when the pinned chdb-core run does not match the expected SHA, successful main-branch conclusion, or expected artifact contents; the static archive test no longer fails on valid prelinked Linux archives
