@afrittoli This PR backports all CI fixes to release branch release-v0.25.x. These changes align to the tektoncd org wide CI adoption practices implemented in the last few months. Since we need the CVE fixes #1631 for this branch, had to correct the CI for this branch as well.

Summary of changes done:

File	Change Summary
ci.yaml	New file: Consolidates CI into a single workflow with change detection (docs vs non-docs), build, lint, test, e2e, and a ci-summary gate job (https://github.com/tektoncd/plumbing/blob/main/config/repo-checks.yaml)
.github/workflows/lint.yaml	Deleted: Lint is now part of ci.yaml
codeql.yml	Pin action versions to full SHAs (e.g. actions/checkout, codeql-action/*)
kind-e2e.yaml	Switch trigger to workflow_call (called from ci.yaml); update k8s matrix to v1.31–v1.33; bump Tekton Pipelines LTS versions; add concurrency and permissions
reusable-e2e.yaml	Pin action SHAs; upgrade sigstore/scaffolding to v0.7.24; switch Tekton release URL to infra.tekton.dev; reorder steps (checkout first); replace manual tkn install with system tkn; add SKIP_INITIALIZE support; improve failure diagnostics
test-on-crc.yaml	Minor whitespace fix
.golangci.yaml	Migrate to golangci-lint v2 config format; move gofmt/goimports to formatters section; restructure depguard, exclusions, and issues settings
.yamllint	New file — Adds yamllint configuration (ignores vendor, configures rules)
Makefile	New file — Adds standard Make targets: build, test (unit/e2e), lint (golangci-lint, goimports, yamllint), clean, help
e2e-common.sh	Bump tkn CLI version 0.20.0 → 0.41.0; fix tarball path to use tmp
e2e-tests.sh	Add SKIP_INITIALIZE flag support; add GCE_METADATA_HOST default; install go-junit-report; remove hardcoded pipeline release URL
spire.yaml	Bump SPIRE images from gcr.io/spiffe-io (v1.0.2) to ghcr.io/spiffe (v1.13.1); fix allow_insecure_scheme type; remove default_svid_ttl; clean up indentation
vault.yaml	Remove empty annotations: stubs; fix indentation in commented-out volumeClaimTemplates
