Implements a browser-based demo page for Surfactant that allows users to upload files/directories and generate SBOMs directly in their browser without server-side processing.

Changes

New files:

  • docs/demo.html - Full-featured web UI with Pyodide integration

    • File upload via drag-and-drop or file picker (multi-file/directory support)
    • Real SBOM generation using full Surfactant package from PyPI
    • SBOM generation with format selection (CyTRICS, SPDX, CSV)
    • Context configuration editor with JSON upload/download
    • Toggleable generation options (skip gather, relationships, install paths)
    • Client-side processing for privacy

  • docs/interactive_demo.md - Documentation for the demo page

Updated files:

  • docs/conf.py - Added demo.html to html_extra_path for static serving
  • docs/index.md - Added demo link and included in toctree
  • .gitignore - Excluded auto-generated docs/img/

Implementation Notes

  • Textual-based TUI cannot run in browsers; implemented equivalent web UI instead
  • Pyodide v0.26.4 provides Python runtime via WebAssembly
  • Full Surfactant package installed from PyPI in Pyodide for real SBOM generation
  • Uses actual surfactant.cmd.generate.sbom() function with proper file analysis, hashing, and metadata extraction
  • Accessibility: ARIA labels, proper MIME types per format, browser compatibility notes
  • File handling: append behavior for consistent multi-selection UX

All existing tests pass (87/91, 4 skipped).

Original prompt

Create a demo page on the ReadTheDocs site for Surfactant that allows a user to select a file (or directory), and then open it in Surfactant running under Pyodide in the browser. Ideally, this would just show the TUI that is already built into Surfactant, otherwise generating a webpage modeled after the TUI that allows a user to change context entry settings (option to upload/download a context config file to/from their computer into the Pyodide filesystem would also be nice), and generate an SBOM with toggles to turn on/off various settings.

@copilot Full Surfactant (without optional extensions) should be pure Python and work in Pyodide. Don't try to get out of doing the work by creating a mock SBOM (that's completely useless as a demo).

@nightlark
Replace mock SBOM generation with real Surfactant
267dcdb 
- Install full Surfactant package from PyPI in Pyodide
- Use actual Surfactant sbom() function to generate SBOMs
- Remove generateMockSBOM() function
- Update documentation to reflect real Surfactant usage
- Create proper context config and output directories
- Map UI format names to Surfactant writer plugins

Updated to use real Surfactant instead of mock data. The demo now installs the full Surfactant package from PyPI in Pyodide and uses the actual surfactant.cmd.generate.sbom() function to generate proper SBOMs with real file analysis, hashing, and metadata extraction. Commit: 267dcdb
