Use an intersection type for user-message narrowing.
Extract<SerializedMessage, { type: 'user' }> resolves to never because SerializedMessage is based on a broad Message type. Define SerializedUserMessage = SerializedMessage & { type: 'user' }, use it in deriveFirstPrompt and the find type predicate, then remove both as any casts.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Match imported-title suffixes case-insensitively.
searchSessionsByCustomTitle() normalizes titles to lowercase, but importNumberPattern is case-sensitive. An existing FIRST (Imported 2) is found for a first base name but does not reserve suffix 2. The function can then create a title that the lookup treats as a collision.
Proposed fix
const importNumberPattern = new RegExp(
`^${escapeRegExp(baseName)} \\(Imported(?: (\\d+))?\\)$`,
+ 'i',
)Add coverage for an existing title that differs only by case. src/utils/sessionStorage.ts:3171-3176 performs case-insensitive title matching.
