v0.1.0

Initial release.

Added

• Runtime loading of PDFium via libloading with a documented discovery
  chain (PDFIUM_LIB_PATH, executable directory, target/pdfium, system
  loader), explicit-path loading, and eager symbol resolution — an
  incompatible library fails at load time with
  LoadError::MissingSymbol.
• Process-wide singleton with every FFI call serialized through one
  global mutex; all handle types are Send + Sync.
• Document loading from memory or file with typed errors for encrypted
  (PasswordRequired / IncorrectPassword / UnsupportedSecurity) and
  malformed (InvalidPdf) input; metadata, permissions, PDF version,
  security handler revision, page labels, and cheap per-page size
  queries.
• Page rendering to owned pixel buffers: scale / DPI / width / height /
  fit / exact sizing, Bgra8 / Rgba8 / Bgr8 / Gray8 formats,
  background colors, extra rotation, annotation and form-field layers,
  anti-aliasing toggles, and a pre-allocation output-size ceiling
  (RenderConfig::max_output_bytes, default 1 GiB, enforced via
  Error::RenderTooLarge).
• Pixel/page coordinate mapping: every render carries a PageTransform
  (points and rects, both directions) derived from PDFium's own
  device-to-page mapping; PdfPage::transform_for computes it without
  rendering.
• Text extraction with per-character geometry (unicode, tight and loose
  bounds, baseline origin).
• AcroForm field appearance rendering via an owned form-fill environment.
• Public sys module exposing the raw function table, gated by the
  documented ffi_lock serialization contract.
• Binary acquisition tooling: pdfium.lock.json pin
  (chromium/7988, PDFium 153.0.7988.0) with sha256 verification,
  cargo xtask fetch-pdfium, and cargo xtask repackage for the
  native-v* release archives.
