Malte UblandClaude Opus 5.5 091b8f1934 Report which packages and modules would run in a Node island ...

Adds the report-only Node island policy, configuration and detector of
the scope-B plan (milestone NI-2). Coverage now lists the npm packages a
build would run in a Node island and why, gap islands first, without
changing code generation.

- project-config.ts reads the `scriptc` key of the entry's package.json
  with a schema; an unknown value in `scriptc.packages` or
  `scriptc.nodeIslands` is SC8004 instead of being ignored. Package shims
  and the WebAssembly scanner read through it.
- node-islands/: origin (user, npm, shim, builtin; package instances),
  rules R1.1-R2.5 and the four classes, a syntactic pre-scan for R1/R2
  markers, classification of refusals and runtime fences (reason ids at
  the refusal sites that need them), the policy (auto, explicit, off;
  forced node and native packages; marked user modules) and the report
  with island closure.
- coverage: a "Node islands" section, `--explain-island=<pkg>`, a
  `nodeIslands` field in the diagnostics envelope, and `--fail-on`
  `node-islands`, `eager-node-islands` and `island-gaps`.
- CLI: `--node-islands`, `--node-island`, `--native`, `--node` (validated,
  report-only) and `--strict-user-js` (SC8101-SC8105 for R2 constructs in
  user JavaScript).
