skylar taylor-barrick 392406eb4a fix(content): read a comment at the end of a content stream as the renderer does (#3081 )

Pieces::join separated a page's content streams with a newline, which ended
a comment left open at the end of one stream. hayro, MuPDF and Poppler join
them with a space, so the comment runs on into the next stream and hides its
first line. Edit text, object_list, the redaction audit, redaction and the
Office/HTML export therefore saw text and boxes that nothing draws, and
redacting unrelated text on the page made the hidden content visible: the
rewritten stream dropped the comment.

- Pieces::join uses a space, so every reader of the joined streams agrees
  with rendering.
- The parser records, per piece, whether a top-level comment runs into it
  and out of it (boundaries only, not every comment). A redaction rewrite
  of a piece ends an incoming comment before its first operator and leaves
  an outgoing one open, so hidden content stays hidden.
- Reading for export parses the streams joined, instead of one by one.
- The redaction tag check compares the joined streams the same way.
- Pieces::piece_of uses a binary search.

Layer L2: content streams (ISO 32000-2 §7.8.2, §8, §9).

let parsed = parse(&stream.decoded()?);       // operators with operands and source spans
for op in &parsed.ops { if op.is("Tj") { /* … */ } }
let bytes = serialize_ops(&parsed.ops);       // write back (inline images kept whole)
let m = Matrix::from_operands(&op.operands);  // cm / Tm arithmetic, invert, bbox

The parser is tolerant (unreadable bytes are skipped and counted, never fatal) and never panics. redact and (later) edit build their interpreters on it; the graphics-state tracker and the Patch API of architecture §6 grow here.

Unfiltered inline images with built-in or Indexed colour spaces, and image masks, use their sample layout (including per-row byte padding) to locate EI. This preserves pixel bytes that look like the terminator. Filtered images and resource-defined colour spaces retain the tolerant delimiter heuristic; damaged or truncated layouts fall back to it too.
