Summary

• CI (.github/workflows/ci.yml): on pushes to main and on PRs it runs npm ci, compiles, lints, runs the tests under xvfb-run with coverage, fails below 85% line coverage, and uploads the coverage report.
• Test runner: moved to @vscode/test-cli so coverage is measured inside the extension host. This replaces the hand-rolled runTest.ts and suite/index.ts.
• Tests: 32 total.
  • Unit tests for the file extension → Mol* format mapping and the generated load commands.
  • Integration tests for command registration, activateFromFiles (single file, multi-select, nothing selected), activateFromFolder, and start (PDB ID, UniProt ID, cancelled input).
• Coverage: 87% of lines. ESMFold isn't tested because it calls the live ESM Atlas API.

Bug fixes

• .ent, .brk, .mcif, .bcif and .sd files were passed to Mol* under formats it doesn't recognise. The mapping now lives in src/formats.ts.
• IDs and file URLs are now escaped with JSON.stringify before being written into the webview script.
• Closing a panel threw an error because onDidDispose lost this.
• Cancelling the start input box no longer tries to load AlphaFold entry "undefined".
• Added the missing eslint config, so npm run lint runs again.

Also included

This branch also contains the pending molstar 4.8.0 / TypeScript 5 upgrade and the file-handling improvements from molstar_4.8.0, because the new tests depend on that behaviour.

Test plan

• npm ci && npm run test:coverage on a clean checkout (macOS, VS Code 1.144): 32 passing, 87% lines
• CI passes on this PR (Ubuntu + xvfb)
