v1.1.2

This release contains a breaking public API change. TesseractConfig.psm is now optional.
Callers that read or set it as a plain integer must handle None / null — see below.

Changed

• Breaking: TesseractConfig.psm is now Option<i32> (null/None/absent in the bindings)
  and defaults to unset rather than to 3. This fixes supplying a TesseractConfig at all acting
  as a hidden behaviour switch: because several code paths keyed on the struct being absent, a
  caller who set one unrelated field — table detection, a preprocessing knob — silently lost the
  whole-image PSM 11, the vertical-language PSM 5, the layout-region PSM 6, and the sparse-text
  retry, and got Tesseract's PSM 3 instead. TesseractConfig() with default fields is now a
  no-op: the pipeline applies exactly the same automatic PSM it would with no TesseractConfig.
  An explicitly set psm is still honoured. Bindings that model psm as a plain integer expose
  a companion presence check (for example xberg_tesseract_config_has_psm in the C API), since a
  bare integer cannot distinguish "unset" from a real 0.

Fixed

• Fixed a numbered or bulleted list on a scanned page being reconstructed as a table, replacing
  the list text with a mangled grid. A candidate region whose first column is list markers
  (1., a), •) end to end — the header cell included — is now rejected on the OCR routes.
  A genuine numbered table is unaffected: its first column carries a header label (Line,
  Item) above the numbers, which is what separates the two.
• Fixed a table detected on a scanned page having its text returned twice — once as paragraphs,
  once as table cells — in the document content and element tree. This affected every
  output_format; "plain" only appeared to avoid it.
• Fixed PdfConfig.top_margin_fraction / bottom_margin_fraction defaulting to 0.06/0.05
  (6%/5%) since 1.1.0, which silently dropped OCR text — page titles included — in the top and
  bottom bands of every default-config scanned PDF page with no warning. Both now default to
  0.0 (disabled); set them explicitly to filter header/footer content. The nonzero defaults
  also forced every default-config OCR page onto the lossy per-page route instead of a
  document-capable backend's whole-document path; that routing is restored too.
• Fixed rendered PDF pages losing the Tesseract backend's own ProcessingWarnings (including
  the dictionary-filter removal notice) and OCR metadata (psm, language,
  tesseract_dict_invalid_word_ratio), both of which reached the caller for a standalone image
  but were silently dropped for the same page rendered from a PDF.
• Fixed OcrConfig.language being discarded whenever a TesseractConfig was supplied, so a
  German document was OCR'd in English. One precedence rule now governs both Tesseract backends
  and the vertical-language check.
• Fixed supplying any ImageExtractionConfig suppressing document-level OCR on scanned PDFs,
  which returned empty pages with only a debug log.
• Fixed rendered PDF pages ignoring the configured render DPI. target_dpi, min_dpi,
  max_dpi, and auto_adjust_dpi are now honoured. With no configuration the default stays at
  150 DPI, unchanged.
• Fixed suspended hyphens being welded during text assembly, turning onderhouds- en into
  onderhoudsen. A hyphen is now joined only across a genuine visual line break, matching the
  rule the pipeline layer already applied.
• Fixed an unruled full-width band in a ruled table being cut at column positions no rule gives
  it, splitting headings mid-word. A column boundary now counts only where a vertical edge
  actually spans the band.
• Fixed every non-header table cell having its em-dashes, en-dashes and minus signs rewritten to an
  ASCII hyphen, the spaces around a hyphen collapsed, E-/E+ lowercased to e-/e+, and any
  cell consisting solely of a dash emptied. That normalisation is correct for a numeric column (an
  em-dash means nil, 1.5E-05 is an exponent, - 3 is -3) but corrupted prose tables, turning
  Functionaliteit—12 into Functionaliteit-12 and a part code HRE - HReco into HRe-HReco.
  It is now applied only to columns whose data cells are predominantly numeric
  (#1582).
• Fixed the Windows PHP extension archives failing to publish at all. vendor-windows-native-closure.ps1
  repacks a .zip with Compress-Archive, which runs no native command and so never sets
  $LASTEXITCODE; the release workflow gated on it, and an unset $LASTEXITCODE compares as
  non-zero, so every Windows archive was rejected immediately after being vendored successfully.
  Combined with an all-or-nothing matrix gate that withheld the release's PHP assets whenever any
  single leg failed, this left v1.1.0 and v1.1.1 with no PHP binaries at all. Both are fixed: the
  script now sets its exit contract explicitly, matching its sibling scripts, and the upload job
  now ships the archives from the legs that succeeded
  (#1585).
