v2.15.0 - Natural-language quick-add

Added

• The add-task title field is now a Todoist-style quick-add (#72). Type one line and it recognizes, inline, as you type:
  • a due date in natural language - "tomorrow", "friday", "jan 27", "in 3 days", "next week at 4pm"
  • a repeat - "every day", "every weekday", "every other monday", "every 3rd thursday", "monthly on the 1st"
  • #project, @Label (auto-created if new), and p1-p4 priority
• Recognized tokens are highlighted in the field and listed as removable chips below it (click the x to unlink a wrong match). Typing # or @ opens an autosuggest dropdown (arrow keys + Enter, or click). The parsed values also fill the Deadline / Project / Priority / Repeat controls live.
• A bare multi-weekday list like "friday and saturday" (no "every") is treated as those specific days once each - modeled as a weekly repeat ending on the last day - rather than an endless repeat. "every friday and saturday" stays ongoing.

Frontend-only, no migration. Uses chrono-node for the free-form date parsing; recurrence and the symbol tokens are parsed in-house onto the existing recurrence grammar. Also fixes the phone deploy to bundle vendored (file:) dependencies.
