0.3.0

Added

• Filename scheme — the exported PDF no longer has to be named after the note. The
  scheme accepts {title} {date} {time} {folder} and {version}; the default
  {title} keeps the previous behaviour unchanged. An unknown placeholder is left as-is so
  a typo shows up in the filename instead of silently disappearing, and an empty scheme
  falls back to {title}.
• {version} prevents overwriting. Without it, exporting a note twice replaces the
  previous PDF (unchanged behaviour). With it, each export counts up to the next free name
  (Report v1.pdf, Report v2.pdf, …). It has no effect in the attachment folder mode,
  where Obsidian resolves collisions itself.
• Line height and maximum image width are now adjustable. Both settings already
  existed and were already honoured by the PDF engine, but had no control in the Settings
  tab — they could only be changed by editing data.json by hand.

Changed

• The Settings tab is now grouped into five collapsible sections (Output, Page,
  Typography, Content, Pagination) instead of seventeen settings in one flat list.
  Output starts expanded; the others remember whether you left them open. If you ever
  went looking for where the PDF is saved and did not find it: it was always there, just
  buried — it is now the first thing the tab shows.
• Font size, margins and heading orphan control are sliders. As text fields, a value
  outside the allowed range was silently discarded: nothing was saved, nothing was said,
  and the field kept showing the value you typed while the old one stayed in effect. The
  sliders make an invalid value impossible and show the limits up front.
• The custom output folder only appears when the output destination is actually custom
  folder — so it no longer needs a line of text explaining when it applies.

Fixed

• Settings are merged with the shared kit's mergeSettings instead of a flat
  Object.assign. With the new section states, a flat merge would have shared a reference
  with the defaults, and collapsing a section for the first time would have mutated them.
• Both READMEs listed the default font size as 11 pt; it has always been 10.5 pt.
