v0.3.55 | Ruby + PHP language bindings + multi-line heading reading-order fix

Added

• Ruby binding (9th language) — full PDF toolkit for Ruby. Install
  with gem install pdf_oxide. Prebuilt native gems for linux-x86_64,
  linux-aarch64, darwin-x86_64, darwin-arm64, windows-x64 plus a
  source gem. API mirrors the Java binding's 9-class shape
  (PdfDocument, Pdf, PdfPage, PdfPolicy, PdfSigner,
  PdfValidator, DocumentEditor, AutoExtractor,
  MarkdownConverter) so docs and examples are uniform across
  languages. Full feature parity with Python / Java including
  auto-extraction, PAdES B/T/LT signing, destructive redaction,
  office round-trip, and split-by-bookmarks. (#545)
• PHP binding (10th language) — full PDF toolkit for PHP. Install
  with composer require oxide/pdf-oxide. PHP 8.2 / 8.3 / 8.4 / 8.5
  on Linux / macOS / Windows. Same 9-class API shape as Ruby and
  Java. Composer post-install hook fetches the matching prebuilt
  libpdf_oxide per platform with SHA-256 verification. Full feature
  parity with Python / Java. Requires ext-ffi. (#546)

Fixed

• #543 — Long subsection titles in multi-column academic papers
  no longer split when they wrap across column boundaries.
  Discovered while regression-testing v0.3.54 on a 75-PDF corpus.
• #537 (follow-up) — Markdown output now emits Unicode
  bidi-isolation markers around RTL runs detected by the v0.3.54
  Hebrew / RTL detector, so extracted Hebrew / Arabic text renders
  correctly inside mixed-direction paragraphs. Original report by
  alexagr; this completes the markdown emission half deferred
  from v0.3.54.
• #535 (follow-up) — Type 1 built-in encodings, CFF charset,
  and /Differences-array glyph lookups now go through the same
  Adobe Glyph List fallback chain as v0.3.54's main extractor, with
  variant-suffix stripping (A.sc → A, bullet.alt → •,
  fi.001 → fi). Resolves replacement-character (�) leakage on
  PDFs using simple-font encodings without a ToUnicode CMap.
