fix: use --force-replace flag for Helm 4 instead of deprecated --force (#2477)

* fix: use --force-replace flag for Helm 4 instead of deprecated --force

Helm 4 deprecated the --force flag in favor of --force-replace.
This fix detects the Helm version and uses the appropriate flag:
- Helm 4: --force-replace
- Helm 3: --force

Also fixed a nil pointer panic in appendHideNotesFlags when called
with nil SyncOpts.

Fixes #2476

* fix(ci): pin semver to v2.12.0 for Go 1.25 compatibility

semver@latest requires Go 1.26.1 but the project uses Go 1.25.4.
Pinning to v2.12.0 which is compatible with Go 1.25.

* test: add test cases for force flag from defaults with nil release

Add test cases to cover the scenario where release.Force is nil and
HelmDefaults.Force enables force for both Helm 3 and Helm 4.

* test: add nil ops test and rename misleading test names

- Add test case for appendHideNotesFlags with ops=nil to prevent
  regression
- Rename force-from-default-nil-release-* to
  force-from-default-nil-force-* for clarity (release.Force is nil,
  not the release itself)

* refactor: add explicit parentheses for force condition

Add explicit parentheses around the two disjuncts in the force
condition to make the intended grouping unambiguous and easier
to read.

* refactor: check ops nil before Helm version in appendHideNotesFlags

- Swap the order to check ops == nil first to avoid unnecessary
  IsVersionAtLeast call
- Restore the "see Helm release" comment for consistency with other
  flag helpers
