func ResolveTitle ¶

func ResolveTitle(manifestFM, docFM map[string]interface{}, nodeName string, indexFileNames []string, parentName string, isRootIndex bool) string

ResolveTitle determines the display title for a node using a three-level priority chain:

1. manifest frontmatter "title" (non-empty string) — highest priority, explicit override
2. document frontmatter "title" (non-empty string) — from the source .md file
3. filename derivation — index/README nodes use parentName (or "Root" for root index); all others use nodeName. Applied: TrimSuffix ".md", replace "_"/"-" → " ", Title case.

Pure function: no mutations, no I/O.
