* fix: skip failed-prep releases, complete flag wiring, add tests and docs (#64)

Review follow-ups for --allow-failed-releases (#2616):

- Track per-release chart preparation failures in PrepareCharts (returned
  as a map keyed by release) and remove those releases from the state in
  Run.WithPreparedCharts when --allow-failed-releases is set, so a failed
  release is never executed against its original, un-prepared chart
  reference (which could either fail again with a duplicate error or, for
  charts requiring chartify, bypass patches/dependency modifications and
  produce an unintended result). All failures are still reported at the
  end via the aggregated MultiError.
- Complete the release identity on error results from
  prepareChartForRelease so failures are attributed to the correct
  release.
- With --allow-failed-releases, continue building dependencies of the
  remaining charts when 'helm dep build' fails for one release, and skip
  the affected releases during execution.
- Wire --allow-failed-releases into 'helmfile unittest' and 'helmfile
  status'; remove the dead flag wiring for write-values and list (both
  never prepare charts, see commandsSkipChartPrep).
- Simplify control flow (guard clauses, errors.As, drop dead code and
  redundant else branches).
- Add end-to-end coverage in pkg/app/issue_2616_test.go and extend the
  state-level tests; document the flag in docs/cli.md and CHANGELOG.md.
