Furqan-14andClaude Opus 4.8 660649a562 fix(reflow): kill bulge/merge + font-change on edit; add center/right, IME; harden Raw Text

Reflow (primary editor):
- Geometric backstop in reflow_paragraph: adopt any text object fully inside the paragraph
  bbox that the model's objectIndices omitted (PDFium glyph->object map can return -1), so it's
  deleted + its original font is resolved. Fixes both the leftover-glyph "bulge/merge" and the
  font-substitution-on-edit (same root cause). No-op on correctly-indexed paragraphs (gate-proven
  byte-identical: overlay diff unchanged at 1.69%/1.70%).
- Preserve data-fid on edited contentEditable nodes (extractFlatRuns climbs to nearest styled
  ancestor / inherits from adjacent run) so edits keep their real font instead of the dominant.
- Converge preview & commit through one buildReflowData (no preview-OK/commit-wrong drift).
- Center/right alignment: additive emission branch (greedy path only) + heading-align inference.
- IME composition handling (suppress render mid-composition; don't commit on composing Enter).
- Fix WASM document-handle leak (free superseded versions on documentId change/unmount).
- Quiet the backstop instrumentation (warn -> debug) now the root cause is confirmed.

Raw Text / StreamEditor (beta companion):
- Permission-gate both text_objects endpoints behind canModify; label tool "(beta)".
- P1a: preserve TJ kerning numbers for same-length edits (redistribute into original slots),
  fall back to single-string collapse otherwise (never worse than before).
- P1b: reject edits with characters unencodable in the run's font (clear 400 instead of corruption).
- P2a: commit Raw Text edits as a new document version (add_document) and adopt the id via
  pushHistory, so they join undo/redo instead of mutating in place.
- P2b: exact hit-boxes from real font metrics (re-measured once @font-face loads).

WASM preview rebuilt with the reflow changes; cache version bumped.

Bindings — placeholder

Language bindings over the C++ engine. Not implemented yet.

c_abi/ — stable C ABI (int error_code returns, opaque handles). Consumed by .NET and Python ctypes. This ABI is frozen in Phase 0 alongside the PdfDocument / PdfPage interface contracts (Gate G0b) and must not change without a version bump. Phase 3 ships .so / .dylib / .dll packages from it.
python/ — pybind11 module used by the FastAPI gateway. Exposes render_page(), apply_edits(), extract_text().

Internal engine code uses std::expected<T, E>; the C ABI surface translates that to int error_code (engine blueprint §16.2).
