Brandon ThomasandClaude Opus 5.5 ac222e818b Never crash: edit and xfdf have no expect calls

- edit: the substitute font name is a `&str` constant, so there's no `from_utf8(..).expect`.
  Paragraph grouping uses `let … else` / `if let` chains, and the reuse-font path takes the
  metrics with `filter` instead of `expect("checked")`.
- xfdf: a comment key that vanished between listing and lookup is skipped.

Both crates now deny the panic lints. Adds the root clippy.toml (identical to #11) so tests may
still unwrap.

Never crash: edit and xfdf have no expect calls

Cargo.toml

M5.6/M6.7: Comment and form data exchange: new xfdf crate (L4): XFDF (ISO 19444-1) export/import of comments (replies, pop-ups, ink, quads, line ends, flags, colours) and nested field values; FDF both ways; form data as Acrobat XML, CSV and tab-delimited text. Import replaces comments with the same name and sets values through formats/validation (read-only fields take data). Import/Export commands; doc_export_data/doc_import_data tools (69 tools)

printcraft-xfdf

Layer L4: comment and form data exchange (execution plan M5.6, M6.7).

let xml = export_xfdf(&doc, true, true, "form.pdf");   // comments and/or field values
let fdf = export_fdf(&doc, false, true, "form.pdf");
let txt = export_data(&doc, Format::Txt);               // or Xml, Csv
let report = import(&mut doc, &bytes)?;                 // XFDF, FDF, XML, CSV or text, detected

XFDF (ISO 19444-1): every comment type PrintCraft knows (text, free text, line, square, circle, polygon, polyline, markup, stamp, caret, ink, attachments, sound, redact) with rect, name, author, subject, dates, flags, colours, opacity, width, icon, quads, line ends, ink, default appearance, pop-ups and reply threads (inreplyto); field values nested by name.
FDF: fields (with /Kids hierarchies) and comments as direct objects.
Form data: Acrobat's XML (xfdf:original keeps names that aren't XML names), CSV and tab-delimited text (a row of names, a row of values).

Import replaces comments with the same /NM, draws appearances PrintCraft can draw, and sets values through the form's own checks (formats, validation, recalculation); read-only fields take imported values, as in Acrobat. XML is read with roxmltree.
