* Automatic discovery of the scopes.
Issue #61 raised very valid concerns about users configuring scopes that are not supported by the provider.
This change introduces automatic discovery of supported scopes by fetching the provider's discovery document and filtering out unsupported scopes.
Before:
User configures: scopes: ["openid", "profile", "email", "offline_access"]
Self-hosted GitLab: "The requested scope is invalid, unknown, or malformed"
Authentication: ❌ FAILS
After:
User configures: scopes: ["openid", "profile", "email", "offline_access"]
Middleware checks discovery doc → offline_access not supported
Automatically filters to: ["openid", "profile", "email"]
Authentication: ✅ SUCCEEDS

* Fixes issue #51
* Ensure that appended roles are unique. Update the documentation.
* Improvements targetting possible memory usage spikes.
* Additional fixes and cleanup
* Refactoring code to fix the issues identified by the users.
* Modernize run
* Fieldalignment
* Multiple changes to improve performance and reduce complexity.
- Optimise the errors and recovery.
- Deduplicate code in metadata cache.
- Remove unused performance monitoring code.
- Simplify session management and settings handling.
* Fix claims issue.
* Add ability to overwrite the default scopes in the settings file
* Well.. that escalated quickly.
Completely forgot that Traefik uses outdated Yaegi and requires compatibility with 1.20 ( pre-generic Go code ).

* Issue #53: Fix CSRF token handling in reverse proxy
1. ✅ HTTPS Detection Fixed (session.go:723)
- Now uses X-Forwarded-Proto header instead of r.URL.Scheme
- Properly detects HTTPS in reverse proxy environments
2. ✅ SameSite Cookie Attribute Fixed
- Removed automatic SameSiteStrictMode for HTTPS (would break OAuth)
- Keeps SameSiteLaxMode to allow OAuth callbacks from external domains
- Only uses Strict for AJAX requests which don't involve OAuth redirects
3. ✅ Cookie Domain Handling Fixed
- Now respects X-Forwarded-Host header for cookie domain
- Ensures cookies are set for the public domain, not internal proxy domain
4. ✅ EnhanceSessionSecurity Properly Integrated
- Function is now actually called during session save
- Applies security enhancements without breaking OAuth flow
Why Issue #53 Failed Before:
1. Cookies were not marked Secure in HTTPS environments (browser wouldn't send them back)
2. If they had been Secure with SameSite=Strict, Azure callbacks would still fail
3. Cookie domain might have been wrong (internal vs public domain)
Why It Works Now:
1. Cookies are properly marked Secure for HTTPS
2. Uses SameSite=Lax to allow OAuth provider callbacks
3. Cookie domain uses public domain from X-Forwarded-Host
4. CSRF token persists through the entire OAuth flow
* Next set of enhancements together with memory usage improvements.
* Memory leak fixes and optimisations.
* CSRF and Cookie Domain fixes
* fixup! CSRF and Cookie Domain fixes
* Metadata cache leak fix + profiling
* fixup! Metadata cache leak fix + profiling
* Memory leaks hunting, part 1337.
