* test: resolve repository files without climbing directories
Twelve tests and helpers reached shared fixtures, package assets, and workers with ../.. paths from import.meta, which the import rule does not see. They now go through repoPath and testPath, a workspaceRoot() that finds the root by its lockfile, the core package's own root, or the #core alias through import.meta.resolve. The root finder derives its folder from import.meta.url, so Playwright specs running under Node can use the helpers too. open-pencil/no-deep-parent-relative-paths rejects climbing two levels in new URL(…, import.meta.url) and in path calls that start from import.meta.
* fix(lint): catch Windows separators and wrapped import.meta paths, and stop at template expressions
The path rule missed '..\..' and a base such as dirname(fileURLToPath(import.meta.url)), and read `../${folder}` followed by '..' as climbing two levels.
- Rename first-party API, RPC, JSON, CORS, SVG, JSX, and related identifiers to preserve acronym casing
- Keep upstream and serialized boundary names unchanged
- Add a lint guardrail and migration notes for exported APIs
