ci(cleanup): add disk cleanup before checkout (#15077)

ci(cleanup): add disk cleanup before checkout

Add free-disk-space action before checkout in both check and e2e jobs to
prevent disk space issues during build process. The action runs before
checkout to avoid creating files in the git working directory.

Expected to free up 12-16 GB of disk space before build operations,
improving reliability of CI jobs.

feat(deps)!: migrate module path to github.com/kumahq/kuma/v2 (#15032)

## Motivation

Migrate Go module path to `github.com/kumahq/kuma/v2` for semantic
import versioning compliance. This is required for proper Go module
version resolution when Kuma is at v2.x versions.

## Implementation information

This PR includes the complete migration with all post-migration fixes
consolidated from master:

- Updated `go.mod` module declaration to `github.com/kumahq/kuma/v2`
- Mass-replaced ~10,649 import statements across 2,228 files
- Updated 46 `.proto` files `go_package` options
- Updated configuration files (`.golangci.yml`, `mk/*.mk`, shell
scripts)
- Applied post-migration fixes from PRs #14907, #14910, #14911, #14919,
#14961, #14962
- Regenerated all files with new module path

**Post-migration fixes included:**

- PR #14907: Update policy-gen CLI defaults to `/v2` path
- PR #14910: Fix `RelativeToPkgMod` for v2 module paths
- PR #14911: Fix `PostgresContainer` with `-trimpath`
- PR #14919: Hardcode `/v2` in resource-gen
- PR #14961: Update OpenAPI config import paths to `/v2`
- PR #14962: Fix `GO` variable evaluation in makefiles

**Verification:**

- `make check` passes locally
- CI full matrix validation enabled via `ci/run-full-matrix` label

## Supporting documentation

Related: #2073

## BREAKING CHANGE

All Go import paths must be updated from `github.com/kumahq/kuma` to
`github.com/kumahq/kuma/v2` for any code that imports Kuma packages.
This affects all downstream projects, plugins, and extensions.

**Before:**

```go
import "github.com/kumahq/kuma/pkg/core/resources/model"
```

**After:**

```go
import "github.com/kumahq/kuma/v2/pkg/core/resources/model"
```

Users must update their `go.mod` to require `github.com/kumahq/kuma/v2`
instead of `github.com/kumahq/kuma` and update all import statements
accordingly.

fix(tools): backport AddGoComments symlink fix to release-2.11

## Motivation

During /v2 module path migration for Kong Mesh release-2.11, OpenAPI
schema generation removes field descriptions from generated files. This
breaks `make check` because the regenerated
`docs/generated/openapi.yaml` has descriptions stripped out.

The issue occurs because `AddGoComments` from `invopop/jsonschema`
cannot load Go source code comments when Kuma's `resource-gen` tool is
called from downstream projects (Kong Mesh) via symlinks. The function
requires the working directory to be at the module root to find Go
source files.

## Implementation information

This PR backports the fix from release-2.12 (commit 81fdbf8, Kuma PR
#14978).

The fix modifies `tools/resource-gen/pkg/generator/main.go` to:
- Resolve symlinks in the `readDir` path using `filepath.EvalSymlinks`
- Convert to absolute path for correct directory reference
- Temporarily change to the module root directory before calling
`AddGoComments`
- Restore the original working directory immediately after

This ensures OpenAPI schema field descriptions are preserved when
generating schemas from downstream projects.
