release 2.8.0

[arnelirobles]

Version bump and changelog for 2.8.0. No source changes beyond what is already on master.

Minor, not patch: netstandard2.0 becomes netstandard2.0;net8.0 on every package. Purely additive, so existing consumers resolve exactly as before.

Contents:

• @snowyukitty's pooled-buffer fix (ErrorCollection.Create leaks the pooled buffer if enumeration throws #24, fix(extensions): return pooled buffers after enumeration failures #34), which also corrects a second bug the issue did not ask for: using the count actually yielded rather than Count, so a collection that overstates its length no longer exposes stale pooled slots.
• The static-options test isolation fix (master is red: ProblemDetailsFactory's static defaults leak across parallel tests #33, serialise the tests that share ProblemDetailsFactory's static defaults #36).
• The zero-allocation gate, the API approval snapshots, and net8.0 targets.

601 tests pass on a clean solution build. All 8 packages pack at 2.8.0 carrying both target frameworks.
