help RustRover see. You may need below commands. And i may nest things eventually in
/usr/loca/uwu for isolation.

This will tell your linker to look in `/usr/local`, but it may also cause conflicts or unexpected behavior: ```bash echo "/usr/local/lib" | sudo tee /etc/ld.so.conf.d/usr-local.conf sudo ldconfig ```
RustRover default to prebuilt RocksDB if found in
/usr/local

this should also apply to RustRover by default, and you will notice less redundant rebuilding of built static imports.

42 megabytes. 8 minutes. release-max-perf. we need to improve our documentation, so admins understand how to get non-default features. i suspect nothing additional is needed to run the full Complement Test suite and serve all basic homeserver functions. not even URL preview zero overhead: extreme cases may leak IPs or allow forgery attacks. there's no harm in recompiling once you find you want it. testing: add WIP engage target for complement tests (not everyone has buildkit or buildx)
document tech debt: wasteful presence DB i/o and a need for LRU caching

build: prelim support for
bindgen, bundling the RocksDB assembly into standalone Rust binaries
revised commands to build rocksdb static assembly: ```shell DISABLE_JEMALLOC=1 EXTRA_CXXFLAGS="-Wno-error=unused-parameter" make shared_lib static_lib -j$(nproc) sudo make install-shared INSTALL_PATH=/usr/local sudo make install-static INSTALL_PATH=/usr/local sudo ldconfig ```

update env vars defs for building. see below note on DISABLE_JEMALLOC=1,
```shell git clone https://forgejo.ellis.link/continuwuation/rust-rocksdb-zaidoon1.git cd rust-rocksdb-zaidoon1 git checkout 61d9d23872197e9ace4a477f2617d5c9f50ecb23 git submodule update --init --recursive cd librocksdb-sys/rocksdb PORTABLE=0 DISABLE_JEMALLOC=1 CXXFLAGS="-Wno-error=unused-parameter" make shared_lib -j$(nproc) sudo make install-shared INSTALL_PATH=/usr/local sudo ldconfig ```

build(perf): document benefits of pre-compiling rocksdb:
