Function planLinkFixes

planLinkFixes(result: ValidateResult, knownFiles: string[]): PlannedLinkFix[]
Plan fixes for the broken internal links in a validation result.

Only internal file-not-found links are fixable this way -- an external or anchor failure has no file to suggest. Broken links whose target resembles nothing known are left out rather than given a wild guess.
Parameters
- result: ValidateResult
  A completed validation result
- knownFiles: string[]
  Absolute paths of every candidate file in the project
Returns PlannedLinkFix[]
One planned fix per broken internal link that has suggestions
