ci: add dual build artifacts to compare C vs Rust code paths (#2207)

Browse Source 
* fix: flush pending EIT sections in EPG_free() before freeing buffers

* ci: add dual build artifacts to compare C vs Rust code paths

Add -min-rust flag to linux/build that passes -DDISABLE_RUST to gcc,
causing switchable modules (DTVCC, demuxer, AVC, networking, hex utils)
to use their C implementations instead of Rust. The Rust library still
compiles since many modules are Rust-only.

The Linux CI now produces two artifacts:
- "CCExtractor Linux build" — min Rust (C paths where available)
- "CCExtractor Linux build (with migrations)" — max Rust

Both should produce identical output on the sample platform. If they
diverge, it means a Rust port introduced a behavioral difference.

The sample platform will need a corresponding update to recognize and
test the new "with migrations" artifact.
