Prepare for v1.11.0 release (#352)

## Summary
Bump `DriverVersion` to `1.11.0` and add the v1.11.0 section to
`CHANGELOG.md`.

### Changes since v1.10.0
- Enable telemetry by default with DSN-controlled priority (#320, #321,
#322, #349)
- Add SPOG (Custom URL) routing support via `x-databricks-org-id` header
(#347)
- Add statement-level query tag support (#341)
- Add AI coding agent detection to User-Agent header (#326)
- Fix CloudFetch returning stale column names from cached results (#351)
- Fix resource leak: close staging Rows in execStagingOperation (#325)

Internal/infra-only changes are omitted from the user-facing notes (CI
hardening, dependabot bumps, CODEOWNERS).

## Test plan
- [x] `go build ./...` clean
- [x] `go test ./... -count=1 -short` passes locally

## Next steps after merge
1. Tag the merge commit as `v1.11.0` and push the tag
2. Trigger `peco-databricks-sql-go` in
secure-public-registry-releases-eng with `ref=v1.11.0`, `dry-run=true`
to verify
3. Re-run with `dry-run=false` for the actual release
