Merges the impeccable-detect CLI repo (pbakaus/impeccable-cli@831a6cc)
into this repo. The BSL-1.1 license that motivated the split is gone;
everything is now Apache 2.0.
- Add bin/, src/, detection tests and fixtures from CLI repo
- Merge package.json: name → "impeccable", add bin/exports/files fields
- Internal refs now read from local src/ instead of node_modules/
- Update SPDX headers, NOTICE.md, CLAUDE.md, FAQ, npm README
- Add prepack/postpack scripts for CLI-focused README on npm
- Remove terminal license labels (no longer needed)

Overlays for elements inside position:fixed contexts now use
position:fixed with viewport-relative coords, so they stay pinned
on scroll. Extracted shared positionOverlay() helper for consistent
coordinate handling across highlight, reposition, and IO callbacks.
Updated fixture with a real fixed footer scenario.

Overlays are now created hidden and revealed by an IntersectionObserver
(rootMargin: 99999px), so they automatically show/hide when their target
becomes visible or invisible -- handles closed <details>, display:none,
hidden modals, overflow:hidden clipping, etc. without polling.
Adds overlay-positioning.html test fixture with 9 scenario groups
covering transforms, closed details, sticky, overflow, position offsets,
flex/grid, containing-block creators, and combinations.
