RECOMMENDATIONS #8: additive AfterSentAtUtc+AfterId cursor — browse windows fetch
via a (SentAtUtc, Id) keyset filter, O(pageSize) at any depth, COUNT skipped
(TotalCount=-1). Adds the Id tie-break to browse ordering (fixes latent
duplicate/skip on equal timestamps). Verified: InMemory continuation test + a
live-Postgres throwaway proving the Guid cursor comparison translates (removed).
Also root-causes the recurring pre-commit/CI format failures: dotnet-format on
Windows defaulted to CRLF while .gitattributes stores LF — the two fought forever.
Adds .editorconfig (end_of_line=lf etc.) so every tool agrees, and normalises the
straggler files. This bug bit three separate commits before being diagnosed.
