Changes

• Update EF Core and Microsoft.Extensions dependencies to released 11.0.0, use the released .NET 11 SDK, and switch EF package dependencies to the supported [11.0.0,12.0.0) range.
• Remove the RC-era JSON-index annotation workaround and consume EF's per-element sort directions. Replace failure-expecting tests with successful migration scaffolding/compilation and mixed-direction coverage.
• Remove the duplicate provider NULLIF translation now that EF 11 includes the nullability correction; add SQL assertions for the upstream regressions.
• Convert fixed complex-JSON FromSql and navigation ExecuteUpdate cases to positive tests, add the new GroupBy/Distinct DefaultIfEmpty overrides, and update TPC complex-property column-name baselines.

Upstream PRs requiring provider adjustments

• [release/11.0] Fix JSON indexes for SQLite dotnet/efcore#39089 — JSON-index migration annotation handling and per-element sort directions.
• [release/11.0] Don't derive NULLIF nullability from its first argument dotnet/efcore#39315 — Backport the NULLIF nullability correction to EF 11.
• [release/11.0] Preserve ExecuteUpdate target joins during SQL tree pruning dotnet/efcore#39128 — Preserve ExecuteUpdate target joins during pruning.
• [release/11.0] Restore LEFT JOIN translation for correlated grouped DefaultIfEmpty dotnet/efcore#39237 — Restore LEFT JOIN translation for correlated GroupBy/Distinct with DefaultIfEmpty.
• [release/11.0] Fix FromSql queries with JSON-mapped complex properties dotnet/efcore#39295 — Support FromSql with JSON complex properties.
• [release/11.0] Preserve inherited complex-property column prefixes in TPC mappings dotnet/efcore#39270 — Correct inherited/nested complex-property column prefixes with TPC.

Validation

Build and all three provider packages succeed. Full CI-enabled unit and functional suites against isolated PostgreSQL 18.4 with PostGIS 3.6.3: 29,868 passed, 227 skipped, 1 failed.

The sole failure, TPCInheritanceQueryNpgsqlTest.Can_insert_update_delete, expects generated key 4 in its SQL baseline but receives 3. The identical failure was reproduced independently against unchanged RC3 source at fc542f2, so it is left untouched. All upgrade-related tests pass.
