Description of Change

Fixes #55370.

window.open feature parsing currently truncates fractional opacity values with parseInt: opacity=0.75 becomes 0, making the resulting window invisible. Parse opacity with parseFloat while retaining integer parsing for position and size features.

Added coverage for opacity values 0, 0.1, 0.75 and 1, and a mixed feature string that verifies width, height, left and top still become integers.

Validation on Windows with Node 24.22.1: all 11 tests in spec/parse-features-string.spec.ts pass using a temporary Node-pool Vitest configuration that runs the TypeScript source directly. Three of those tests fail on the unchanged source. Oxfmt and Oxlint pass for both changed files, and git diff --check passes. A full Electron build, native BrowserWindow integration test and npm test have not run locally.

AI assistance: OpenAI Codex assisted with implementation and tests. I reviewed the final diff before submission. The commit includes Assisted-By: OpenAI Codex and a verified signature.
