fix: add trackFailOnError option to control kubedog exit code (#2576)

* fix: add trackFailOnError option to control kubedog exit code behavior

When kubedog release tracking fails (e.g. pod ImagePullBackOff), helmfile
exits with code 0 instead of a non-zero exit code. Add a trackFailOnError
configuration option (default: false) that when set to true, propagates
kubedog tracking failures to the exit code.

The option is available as:
- Per-release YAML: trackFailOnError: true
- CLI flag: --track-fail-on-error (sync and apply commands)

Extract trackReleaseIfEnabled helper to consolidate kubedog tracking logic
from two duplicated call sites into a single maintainable method.

Fixes #2507

* fix: add //go:build ignore to server.go to fix go test CI failure

The test/integration/test-cases/issue-2103/input/server.go is a
package main helper binary used by the issue-2103 integration test.
When go test -coverprofile runs on this package, it fails with
"go: no such tool covdata" in the CI environment.

Adding //go:build ignore excludes the file from go list ./... (and
therefore from PKGS in the Makefile), while still allowing the
integration test to build it explicitly via file path:
  go build -o server ./path/to/server.go

* fix: update TestGenerateID expected hashes after adding TrackFailOnError field

Adding TrackFailOnError *bool to ReleaseSpec changed the spew
serialization of the struct, which changed the FNV-32a hash values
produced by generateValuesID. Update temp_test.go with the new
expected hash strings.
