/**
* Extract every module specifier from TypeScript/NodeNext ESM source.
*
* The import-discipline checks below judge *specifiers*, so a specifier this
* helper fails to surface is silently exempt from the boundary. It therefore
* covers all the static-graph import forms this project can use, in either
* quote style, so no forbidden dependency can hide behind syntax:
*
* - static: `import x from '...'` / `import x from "..."`
* (including multi-line `import type { ... } from '...'`)
* - side-effect: `import '...'` / `import "..."`
* - dynamic: `import('...')` / `import("...")`
* - re-export: `export { x } from '...'` / `export * from "..."`
*
* `import.meta.url` is deliberately not matched: the `import` keyword must be
* followed by whitespace (static/side-effect) or `(` (dynamic), and `.` is
* neither. This is a bounded lexical scan, not a parser — no AST dependency is
* introduced, and, like the original scanner, it does not exclude specifiers
* that appear inside comments.

P2 Badge Capture dynamic imports that pass options

When a host file uses the standard two-argument dynamic-import syntax, such as import('../domain/foo.js', { with: { type: 'json' } }), this regexp requires ) immediately after the closing quote and extracts nothing. Both import-discipline checks then skip the forbidden dependency entirely, despite the helper's promise to cover dynamic imports; allow the optional comma/options argument and add a fixture for this valid NodeNext form.

Useful? React with 👍 / 👎.

// re-export bindings: `export { x } from 'S'`, `export * from 'S'`.

Make the ESM scanner token-aware.

extractModuleSpecifiers misses valid forbidden imports when comments occur between tokens. It also misses dynamic imports with options, such as import('../domain/foo.js', { with: { type: 'json' } }). These forms bypass the purity checks. Use a TypeScript parser or token-aware scanner, and add fixtures for comment separators and dynamic-import options.

In `@tests/cockpit-host/purity.test.ts` around lines 49 - 53, Update
extractModuleSpecifiers to use a TypeScript parser or token-aware scanner so it
detects static imports and re-exports when comments separate tokens, plus
dynamic imports with a second options argument. Add fixtures covering both
comment-separated module specifiers and dynamic imports with import options,
while preserving existing purity checks.
