Update dependency @types/estree to v1.0.9 (with type adaptations)

[martin-henz]

Updates @types/estree to 1.0.9. Unlike a normal Renovate lockfile bump, this version's updated ESTree types model newer ECMAScript constructs, which broke compilation in 28 places. This PR includes the source adaptations so the build passes.

Changes

• Import/export specifier endpoints are now Identifier | Literal — ES2022 allows arbitrary module namespace names (e.g. export { x as "y" }). Added a getSpecifierName helper in utils/ast/helpers.ts and routed .name accesses through it. Source only supports identifier names, so it falls back to the literal's value.
• ImportDeclaration now requires attributes (import attributes) — set to [] in the importDeclaration AST constructor.
• BinaryExpression.left is now Expression | PrivateIdentifier (private-in expressions) — narrowed with casts in the transpiler and stepper, since private fields are not valid in Source.

Verification

• yarn build passes (0 type errors)
• eslint clean on changed files
• 885 tests pass across preprocessor / transpiler / stepper / stdlib / parser / cse-machine / finder / utils-ast

Note

Supersedes the lockfile-only Renovate PR #1766, which fails CI on its own because it lacks these source changes. That PR can be closed once this merges.

Code Review

This pull request introduces support for ES2022 string literal import and export specifiers by adding a helper function getSpecifierName to handle both Identifier and Literal nodes. This helper is integrated across the interpreter, finder, preprocessor, parser rules, and standard library modules. Additionally, the PR updates @types/estree to version 1.0.9, adds type assertions for binary expression operands, and includes an empty attributes array when creating import declarations. There are no review comments to evaluate, and I have no further feedback to provide.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
