GetAllServices() throws because the generic helper forwards through native non-generic enumeration, which requires reference-type covariance. Restore List aggregation with GetServices() and GetKeyedServices(), preserving authoritative snapshot keys, explicit enumerable precedence, multiplicity, AnyKey exclusion and private decoration-slot filtering.

Fixes #85.

Verification

• Test-first commit 67bc946: 30 failures and 2 passing reference controls on each of net472, net8.0, net9.0 and net10.0 before changing production code.
• All 1,167 tests pass on each of the four targets after the fix; 32 new cases cover int/custom structs, empty/unkeyed/keyed/mixed groups, duplicate registrations, explicit instance/factory enumerables, metadata mutation and legacy non-factory providers.
• Full Release solution build passes, including netstandard2.0. The two existing net472 package-support warnings remain.
• Native DI 10.0.0 hot-cache checks pass on all four targets, with 100 interleaved enumerations after observed native compilation.
• Existing open/closed-generic merging, AnyKey and decoration tests pass in the full suites.
• Changelog updated under vNext Bug Fixes; CRLF and source encoding preserved; whitespace check passes.

Windows CI run 37631908863 passed for final head 1f44d35: 1,167 tests on each of net472/net8.0/net9.0/net10.0, plus all four native hot-cache checks. Checkout logs confirm the tested PR merge contains this exact head and develop 91c262e. Pack and Publish were skipped. This PR stays draft for human review.
