Summary

• Enable [Updatable] on C# 14 instance extension methods, reusing the classic update emitter with the extension receiver as the source argument.
• Enable [Adapt] on C# 14 instance extension methods, including explicit map/expression/update flags and existing adaptation validation.
• Preserve projection-only semantics for C# 14 getter-only extension properties and unsupported-form diagnostics.
• Bump package version from 0.8.0 to 0.8.1 and refresh all 51 generated-source snapshots.
• Update README, extension compatibility matrix, AI-agent skill references and proposed 0.8.1 release notes.

Tests

• Generator compile/runtime test: projection, update and adaptation on one C# 14 instance extension method; destination preservation.
• Negative regression: value-type update reports AM0001.
• Integration test: generated update and adapted map/update/projection plus EF Core SQLite projection.
• Packaged Roslyn 5+ consumer exercises new APIs; classic Roslyn 4.x consumer remains compatible.

Validation

GitHub Actions: PASS — Build NuGet package #41724444267.

• Restore, Release build and full test suite: pass.
• NuGet package verification and packaging: pass.
• Actual Roslyn compiler compatibility checks (4.8, 4.14, 5.0 and SDK 5.9): pass.
• Package-consumer runtime verification: pass.
• No local .NET SDK was available; validations ran in GitHub Actions.

Scope

C# 14 extension properties remain projection-only. No generic/block-bodied extension member support, no NuGet publication or tagging. Leave open for owner review and approval; do not auto-merge.
