LGUG2Z b53de81754 perf(cargo): make schemars derives optional
This commit makes all schemars::JsonSchema derives optional. After
analyzing the output of cargo build timings and llvm-lines, it was clear
that the majority of the 2m+ incremental dev build times was taken up by
codegen, and the majority of it by schemars.

Developers can now run cargo commands with --no-default-features to
disable schemars::JsonSchema codegen, and all justfile commands have
been updated to take this flag by default, with the exception of the
jsonschema target, which will compile with all derives required to
export the various jsonschema files.

Incremental dev build times for komorebi.exe on my machine are now at
around ~18s, while clean dev build times for the entire workspace are at
around ~1m.
