The initial config-store approach failed because Astro's injected routes
run in isolated contexts during prerendering and don't have access to
global state set during astro:config:setup.
Solution: Created a Vite plugin that provides the configuration through
a virtual module (virtual:@astrojs/discovery/config) which routes can
import at build time.
Changes:
- Added Vite plugin in astro:config:setup hook
- Updated all route handlers to import from virtual module
- Changed version from date-based (2025.11.03) to semantic (1.0.0) per npm requirements
- Added @ts-ignore comments for virtual module imports
Testing: Verified in test project that all configuration now properly
passes through to generated files (robots.txt, llms.txt, humans.txt).
