This commit adds comprehensive support for Helm 4 while maintaining
full backward compatibility with Helm 3. The implementation includes:
- Updated helm version detection to support both Helm 3 and Helm 4
- Added HELMFILE_HELM4 environment variable to control Helm version
- Modified helm execution paths to handle version-specific binaries
- Updated helm plugin installation to support split architecture
- Helm 4: Uses split plugin architecture (3 separate .tgz files)
- helm-secrets.tgz
- helm-secrets-getter.tgz
- helm-secrets-post-renderer.tgz
- Helm 3: Continues using single plugin installation
- Updated Dockerfiles, CI workflows, and core installation code
- Helm 4 requires post-renderers to be plugins, not executable scripts
- Created Helm plugin structure for integration tests
- Updated helmfile.yaml templates to dynamically select renderer type
- Added test plugins: add-cm, add-cm1, add-cm2
- Updated integration tests for Helm 3/4 compatibility
- Created Helm 4 variant expected output files
- Fixed test determinism issues (repo cleanup between iterations)
- Added version-specific output filtering for warnings/messages
- Updated workflows to test both Helm 3 and Helm 4
- Matrix testing across Helm versions
- Updated helm-diff to v3.14.0 for compatibility
- Updated README and docs with Helm 4 information
- Added migration guidance
- Updated version requirements
All changes are backward compatible - existing Helm 3 users will
see no behavior changes.
fix: update Helm 4 lint expected output to match filtered output
The grep filter removes the semver warning, so the expected output
should not include it. Updated lint-helm4 files to match the filtered
output (warning removed, no extra blank line).

All the dependencies get correctly installed when dealing with remote
charts.
If there's a local chart that depends on remote dependencies then those
don't get automatically installed. See #526. They end up with this
error:
```
Error: no cached repository for helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272 found. (try 'helm repo update'): open /root/.cache/helm/repository/helm-manager-b6cf96b91af4f01317d185adfbe32610179e5246214be9646a52cb0b86032272-index.yaml: no such file or directory
```
One workaround for that would be to add the repositories from the local
charts. Something like this:
```
cd local-chart/ && helm dependency list $dir 2> /dev/null | tail +2 | head -n -1 | awk '{ print "helm repo add " $1 " " $3 }' | while read cmd; do $cmd; done
```
This however is not trivial to parse and implement.
An easier fix which I did here is just to not allow doing
`--skip-refresh` for local repositories.

1. only implement post-renderer flags this patch
2. As mumoshu advise, add helmfile flags `--post-render` and add the
postRenderer config in helmDefaults and release. the priority is
helmfile flags > release > helmDefaults.
3. fix the test case in state_test.go and some other tests.

Parses a new field in repositories named `skipTLSVerify` and if set to `true`, it appends `--insecure-skip-tls-verify` in `helm repo add` command.
This should be useful with internal self-signed repos, mitm proxies etc.
Resolves#1871
This adds the ability to include the --pass-credentials flag to the helm add repo command by:
- Adding repo.passCredentials to the helmfile yaml
- Changing state, helmexec, and app to include RepositorySpec.PassCredentials
Resolves#1898

Adds a basic support for Helm repositories hosted on Azure Container Registry (not OCI but classic ones). Add a new field to RepositorySpec to state that is externally managed and runs the `az-cli` command instead of the helm one to manage the repository.
* Parse and process helm version using github.com/Masterminds/semver/v3.
* Add --force-update only when Helm version >= 3.3.2, < 3.3.4.
See: https://github.com/helm/helm/pull/8777.
* Add test cases.
- createNamespace is a new attribute that can be added to helmDefaults
or an individual release to enforce the creation of a release namespace
during sync if the namespace does not exist. This leverages helm's
(3.2+) --create-namespace flag for the install/upgrade command. If
running helm < 3.2, the createNamespace attribute has no effect.

* Add option to suppress diff on apply
Add --supress-diff option on apply. Usable for fresh installs when a
lot of output is produces by diff.
Resolves#458
* fix tests for suppress-diff
Runs `helm version` in helmexec.New, and exposes a method on Interface to allow other packages to use the detected version. Preserves compatibility with previous HELMFILE_HELM3 mechanism.
