Fixes #14023 # Description - Prevents "failed to find added variable" when modules export constants with type signatures: ```nushell > module foo { export const bar: int = 2 } Error: nu::parser::unknown_state × Internal error. ╭─[entry #1:1:21] 1 │ module foo { export const bar: int = 2 } · ─────────┬──────── · ╰── failed to find added variable ``` - Returns `name_is_builtin_var` errors for names with type signatures: ```nushell > let env: string = ""; Error: nu::parser::name_is_builtin_var × `env` used as variable name. ╭─[entry #1:1:5] 1 │ let env: string = ""; · ─┬─ · ╰── already a builtin variable ```
