Summary

• Require @solidtv/renderer ^2.0.7 (peer dependency and lockfile).
• Pass the new atlasGroup node prop through to the renderer node. Only props on Solid's list reach the renderer, so it was dropped silently before.
• Keep the DOM renderer building against 2.0.7, which makes rtl a required node prop: DOMNode now stores rtl (default null, inherit) and atlasGroup.

The image atlas

2.0.7 adds an imageAtlas renderer setting (default off, a prototype in this release). With it on, images up to about 510×510 are packed onto shared 1024×1024 pages, so images on one page can draw in one call. atlasGroup keeps a subtree's images on pages of their own, so a row's posters batch together and are freed together when the row scrolls away.

• Apps enable it with createRenderer({ imageAtlas: true }); Solid already passes settings through unchanged.
• atlasGroup does nothing without imageAtlas: true.
• Each group costs at least one 4 MB page, so set it on rows, not cards. A group applies when an image loads; changing it later affects only images loaded afterwards.
• With the setting on, linearGradient, holePunch and blur draw wrong on packed images. This is a renderer limitation, documented in its atlas design note.

Not in this PR: having Row/Column set atlasGroup themselves. It would cost a page per row while the feature is still a prototype, so it's left for a separate decision.

Limits

• The DOM renderer stores rtl but does not mirror layouts, and it has no atlas: atlasGroup is stored only.

Test plan

• New contract test: atlasGroup reaches el.lng at render and when set afterwards (fails without the change)
• npm test: 730 passed, 13 skipped
• npm run tsc, npm run lint and npm run build pass
• npm run test:browser not run
