Module session 

Where a parse happens: one parser, and the queries compiled against it.

Configs live here rather than on Lang because a wasm Language belongs to the WasmStore its parser holds — parser.c dispatches every lex and external-scanner call through that store — so a config compiled for one parser cannot be shared with another.

An injected language’s config must already be in Session::configs when the parse starts: the callback holds configs immutably and cannot compile into it. Session::ensure walks the #set! injection.language names of a query before parsing and compiles each. An injection that names its language through a captured node instead — the language is in the source text — is only painted if that language was already compiled.
