// bindCommonDiffFlags registers the diff flags shared verbatim by
// `helmfile diff` and `helmfile doctor`. Keeping these in one place avoids
// hand-syncing two parallel flag blocks when a new diff flag is added.
//
// Flags NOT registered here (because their help text or default differs
// between diff and doctor) are registered inline in each command:
//
//   - --show-secrets      doctor overrides help: "ignored, secrets always redacted"
//   - --detailed-exitcode doctor overrides help: notes the exit-2 swallow
//   - --context           doctor defaults to 3 (more context for LLM)
//   - --output            diff uses "output"; doctor renames to "diff-output"
//     (doctor's --output selects the report format)
