Function planBodyShortcode

planBodyShortcode(
    currentShortcode: string,
    submittedShortcode: string,
    siblingShortcodes: readonly string[],
    noun: string,
    scope: string,
): BodyShortcodeSavePlan
Validate a possibly-changed shortcode for a body part or body location.

When the submitted shortcode is unchanged it is accepted as-is; otherwise it is checked with validateBodyShortcode. On rejection the plan keeps the entry's current shortcode and reports the reason, so an in-progress edit is never lost to a bad shortcode.

Pure and Foundry-free.
Parameters
- currentShortcode: string
  The shortcode the entry is stored with today.
- submittedShortcode: string
  The shortcode from the edited form (trimmed here).
- siblingShortcodes: readonly string[]
  The shortcodes of the other sibling entries (excluding the one being edited).
- noun: string
  The entry kind, for the message (e.g. "body part").
- scope: string
  Where uniqueness applies, for the message (e.g. "this body").
Returns BodyShortcodeSavePlan
A BodyShortcodeSavePlan.
