[Stereo-Images]

Finish the initial v1.0 release while keeping the musical engine and replay behavior unchanged.

• Set the release/package version to v1.0 / 1.0.0 and align stylesheet, player, and worker cache tags at v1.0. Update the worker harness assertion and browser interception URL.
• Remove the retired experiments/moving-resonators snapshot, staging script, and experimental-preview documentation.
• Move the existing MIT grant into a root LICENSE file and link it from the README.
• Add description, Open Graph, and Twitter card metadata to both pages, backed by a 1200×630 PNG and its editable SVG source.
• Use the requested introductory wording; remove release-specific recording names from engineering documentation and test labels while retaining the score fixtures.
• Calculate Long-export memory guidance at about 35 minutes: 740.88/806.40 MB for the render buffer and 370.44/403.20 MB for the WAV at 44.1/48 kHz. This is planning guidance, not a duration cap.

Export WAV remains visible in Revisit, with Shift+R and Shift+E documented. No synthesis, musical timing, or encoding changes.

Validation: all 54 Node regressions pass with the original baseline. Metadata, image dimensions, version consistency, deleted paths, and README wording checked. All 45 native browser checks pass across Chromium, Firefox, and WebKit in GitHub Actions run 39203860191; both runners also pass all 54 Node regressions.
