0.8.2

What's Changed

[0.8.2] - 2026-09-05

The schedule creator grows out of its dropdowns: a pattern-first builder that
can express any standard cron — including things like "September 23rd through
26th at 9:00" — with a live preview of the next runs, and schedules can now be
edited instead of deleted and recreated.

Added

• Pattern-based schedule builder. The create dialog now starts with six
  sections — Every N, Daily, Weekly, Monthly, Once, and Cron — each with
  purpose-built inputs instead of single-choice dropdowns:
  • Monthly picks days of the month from a 1–31 grid, supports ranges
    ("23rd–26th" → 0 9 23-26 * *) and an optional month restriction
    (0 9 23-26 9 *), with honest notes for months that have no 29th/30th/31st.
  • Weekly multi-selects weekdays (contiguous picks emit ranges:
    Mon–Fri → 30 8 * * 1-5) with Weekdays/Weekend presets.
  • Daily, Weekly, and Monthly accept multiple times per day
    (09:00 and 17:00 → 0 9,17 * * *).
  • Cron is the full-power escape hatch: raw 5- or 6-field expressions
    with per-field breakdown, live validation, and grammar hints (lists,
    ranges, steps, names, @every). Steps, names, and other shapes the
    builder doesn't model stay available here.
• Live preview in the builder. Every keystroke shows a plain-language
  description ("At 09:00, on day 23–26, in Sep"), the generated expression
  with a copy button, and the next five run times with relative offsets. When
  multiple times would cross-fire (9:05 and 10:42 also means 9:42 and 10:05),
  the preview says so explicitly.
• Schedule editing. Schedule cards gain an Edit button; the same dialog
  reopens prefilled and saves through the existing update API. Schedules
  created in the app round-trip back into their builder section; foreign
  expressions open in the Cron section unchanged.
• A cron engine for the frontend (parsing, validation, next-run computation,
  description) that mirrors the daemon's robfig parser exactly, verified
  expression-by-expression against it via a generated golden fixture.

Changed

• Schedule cards and the dashboard's next-run panel describe recurring rules
  in plain language, keeping the raw expression underneath (list) or as a
  tooltip (dashboard) for precision.
• Cron validation in the schedule form now runs the same grammar the daemon
  will apply, with field-accurate messages ("end of range (7) above maximum
  (6)") before anything is saved.
