Corrects the auth README and the getting-started guide against the 10.0.0 API surface.

Changes

• AuthState matches the source: abstract not sealed, no data classes, Error.exception typed Exception, plus reauthenticatedUid, isNotification and the Reauthentication hierarchy.
• MFA Configuration passes mfaConfiguration to FirebaseAuthScreen, and Error Handling covers all 21 AuthException subclasses with an else, mapping the six email-link types to their AuthUIStringProvider copy.
• The 32-row test-tag table becomes the fui_<object>_<constant> naming rule, with the stability promise covering all of FirebaseAuthTestTags. Sign Out documents the Google and Facebook session clearing.
• Theming points at the slot APIs for layout changes, and the getting-started guide is corrected against the GA API, with rememberAuthConfiguration now remembering and the createAuthFlow example launching once rather than on every recreation.
• Snippets that call @Composable APIs alongside applicationContext now sit in setContent { }, where both resolve.
• Drops every beta marker now that 10.0.0 has shipped: the install coordinates, the beta banners, and Config.kt / gradle.properties, which still read 10.0.0-beta05. Documented third-party versions are pinned to the ones 10.0.0 ships with.
• Fixes two AuthException messages that read "You are are attempting...".
• Compiles the password-requirement number pattern in AuthException once instead of on every call.

Code Review

This pull request centralizes the Android Lint configuration in the root build file, applying a uniform policy across all subprojects and removing redundant lint blocks from individual modules. It also refactors error handling and localization in the auth module, mapping specific Firebase Auth error codes to localized messages via AuthUIStringProvider, and improves session cleanup during sign-out. Additionally, ContinueUrlBuilder was refactored to use Uri for safer parameter appending, and numerous localized string resources were updated. The review feedback recommends ensuring the tools namespace is declared in all XML files using tools:ignore to prevent compilation errors, and suggests optimizing regex instantiation by extracting the pattern to a companion object constant.

One change on the getting-started sign-in snippet. Everything else I checked against the source lines up 👍
