Rename the frontend parsing module from `parseTaskText` to `quickAddMagic`
for clarity. The module handles much more than text parsing — it's the
core of the quick add magic feature. This rename makes its purpose
immediately obvious and aligns with how the feature is referenced
throughout the UI and documentation.
No logic changes — only directory/file renames and import updates.
Split the monolithic parseTaskText.ts into a parseTaskText/ directory with
separate files for types, prefixes, prefix parsing, priority parsing, repeat
parsing, date parsing, and text cleanup. Moved parseDate.ts from helpers/time/
into the module since it's only consumed by the task text parser. Barrel export
in index.ts maintains backward compatibility — no consumer import changes needed.
