Editor support (wscripti / LSP)

config-weave wscripti emits the exact host interface so the wscript LSP type-checks scripts against it.

config-weave wscripti [outdir] emits weave.wscripti — the full host interface — plus a starter wscript.toml. With those next to your scripts, wscript check and the wscript LSP type-check scripts against the exact config-weave host surface: host-API misuse becomes a compile-time error, also caught by config-weave validate.
