Colophon 0.5.0

Added

• StoryGraph import inside Obsidian: the new Import page (dv.view("Colophon/import")) reads a CSV chosen in the
  file picker, shows a preview (new, already imported, ambiguous and unusable rows, planned note names, readings and
  warnings) and creates the notes through the Vault API after you confirm. No Node, no file system path. The installer
  places Import.md next to Statistics.md (--skip-import leaves it out) and the statistics page links to it.
• Limits for a StoryGraph CSV, in the import page and in import-storygraph.mjs: 10 MB, 20,000 rows, 10,000 characters
  in a field. A larger file is refused; a row with a longer field is skipped and reported.

Changed

• The StoryGraph conversion, identities, plan and note text moved to Colophon/storygraph.js, which the command-line
  importer and the import page both run. The command line, its report and the notes it writes are unchanged.
  storygraph-readings.mjs is gone from the archive; the importers now need the Colophon folder next to them, as the
  archive has it.
• The README is an overview with a quick start. Settings, the properties of a book note and importing are described in
  docs/SETTINGS.md, docs/NOTES.md and docs/IMPORT.md; docs/INSTALL.md explains how to update an installation.
