GLIBC_2.39 not found on Linux

Mason’s tree-sitter-cli GitHub linux-x64 binary is linked against GLIBC 2.39 (Ubuntu 24.04). Ubuntu 22.04 ships GLIBC 2.35, so :TSInstall fails with:

tree-sitter: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found

make linux-deps compiles tree-sitter-cli with cargo against the host libc and removes the broken Mason copy. nvim also drops a non-runnable Mason binary on startup.
