0.5.0

Added

• list_notes tool. All notes in a vault folder — with the frontmatter fields you
  ask for — in one call, instead of opening notes one by one or inferring a list from
  prose read elsewhere. Frontmatter comes from Obsidian's metadataCache, so no note
  is read from disk just to list it.
  • A capped result says so in line 1, not as a footnote below the list: the error
    this tool exists to prevent is "incomplete, looks complete", and a warning at the
    end of a long list reproduces exactly that.
  • An empty folder is reported as an error with suggestions, not an empty list —
    "folder is empty" and "folder name is wrong" would otherwise look identical.
  • New setting "List limit" (listNotesMaxRows, default 150, range 20–1000) — a
    visible cap rather than a silent one, in the same spirit as the skill budget.
  • A missing folder argument is reported as an error, not silently treated as
    the vault root — folder: "" still means the root, but only when passed explicitly.
