feat: separate AGPL libraries and add dynamic WASM loading
- Add WASM settings page for configuring external AGPL modules - Implement dynamic loading for PyMuPDF, Ghostscript, and CoherentPDF - Add Cloudflare Worker proxy for serving WASM files with CORS - Update all affected tool pages to check WASM availability - Add showWasmRequiredDialog for missing module configuration Documentation: - Update README, licensing.html, and docs to clarify AGPL components are not bundled and must be configured separately - Add WASM-PROXY.md deployment guide with recommended source URLs - Rename "CPDF" to "CoherentPDF" for consistency
