Merge main into dev/v0.33-windows

[Laksh (lakshk98)]

Description

This PR merges  upstream/main  into  dev/v0.0.33-windows , resolving conflicts across Dockerfiles, workflow files, Helm values, E2E tests, and auto-generated protobuf files.

Merge conflict resolutions

For most conflicts, upstream changes were taken as-is. Notable exceptions:

•  .github/workflows/e2e-test-event-writer.yml  — kept our version, which includes Windows-specific build steps (LLVM, MSBuild, eBPF store, Docker daemon) absent from upstream's skeleton.
•  deploy/.../values.yaml  — introduced  enablePodLevel_win: true  to decouple Windows pod-level metrics from the upstream Linux default ( enablePodLevel: false ), following the existing  enabledPlugin_linux / enabledPlugin_win  pattern. Also kept  enabledPlugin_win  with  ebpfwindows  and  enableAnnotations: true .
•  pkg/utils/metadata_*.pb.go  — regenerated from the auto-merged  .proto  (which combined our Cilium eBPF drop reasons with upstream's HNS/NDIS drop reasons and sampling fields).
•  test/e2e/retina_e2e_test.go  — kept Windows  UnLoadAndPinWinBPFJob  step; dropped stale  ValidateHubble  reference (renamed upstream); took upstream's  InstallAndTestHubbleMetrics  and  ValidateCapture .
•  controller/Dockerfile  /  cli/Dockerfile  — took upstream's  bpf-gen  stage refactor and Azure Linux 3.0 base image upgrade.

Post-merge fixes

After the merge,  Removed usage of the hubble parser options  addresses build failures introduced by the merge — upstream changes that conflicted with our usage of hubble parser options required removing that dependency.

Lint fixes

The final commit fixes lint errors surfaced by the linter running over all files touched by the merge.

   “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or
   otherwise designated in writing by You as “Not a Submission.”
   “Submission” means the Code and any other copyrightable material Submitted by You, including any
