Note that I titled this new ADR as 00021 to leave space for potentially correctly the multiple 00018's that exist as noted in #162 but please let me know if you'd like me to close the gap back to 00019. |

Adds a `[target.x86_64-unknown-linux-gnu]` section to `.cargo/config.toml` to enable split debug info for x86-64 Linux builds. Without this block, target-specific `rustflags` tables fully replace `[build].rustflags` rather than merging, so the `x86_64-unknown-linux-gnu` target was silently falling back to the `[build]` defaults - which don't set split-debuginfo at all, so x86_64 Linux fell back to rustc's platform default of off — full DWARF embedded directly in the .so/binary rather than split into a companion file, producing release artifacts noticeably larger than every other platform. The new block repeats the required cfg and codegen flags. Signed-off-by: Ryan Carbotte <ryancarbotte@gmail.com>
