Wondr 106c7e7b77 grep: make the literal-only matcher a cargo feature instead of a WASI gate
onig_sys builds oniguruma from C sources, so `cargo check --target
wasm32-wasip1` fails unless the caller supplies a C WASI sysroot. Add a
default-on `oniguruma` feature; `--no-default-features` drops the C
dependency and falls back to a literal-only matcher that reports an
explicit error for patterns needing a regex engine.

Gating on the feature rather than on `target_os = "wasi"` keeps the real
engine for WASI builds that do have a sysroot: oniguruma compiles and
passes the full BRE/ERE/-P suite on wasm32-wasip2 when CC_wasm32_wasip2
and CFLAGS_wasm32_wasip2 point at a wasi-sdk.

CI checks wasm32-wasip1 with --no-default-features and builds and tests
the fallback natively.
