Add pdftract grep subcommand with ripgrep-style flag compatibility.
Implements all flags from the plan options table with proper defaults:
- Literal match mode by default (-F style)
- -E for full regex mode
- -i for case-insensitive search
- -w for word boundaries
- -v for invert match
- -l, -c for output modes
- -j for thread control
- --ocr, --json, --highlight DIR
- --progress/--no-progress/--progress-json
- Feature-gated behind 'grep' feature flag
Unit tests cover all flag combinations and edge cases.
Stub implementation exits with code 2 pending 7.8.2-7.8.10.

Added CM_ARG_COUNT and CM_DEGENERATE diagnostic codes for the cm
operator. The cm operator was already implemented in render.rs and
type3_rasterizer.rs; this change adds proper error handling for:
- Wrong argument count (must be exactly 6 numbers)
- Degenerate matrices (NaN values or determinant == 0)
When errors occur, diagnostics are emitted and the CTM is not modified
(clamped to identity).
Closes: pdftract-p7yll
Files modified:
- crates/pdftract-core/src/diagnostics.rs: Added CmArgCount, CmDegenerate
- crates/pdftract-core/src/render.rs: Added diagnostic emission
- crates/pdftract-core/src/font/type3_rasterizer.rs: Added diagnostic emission
- crates/pdftract-cli/src/main.rs: Added CLI output for new diagnostics

Add data-span-index attribute to span rectangles for click navigation
between SVG canvas and JSON-tree panel. Updated render_spans() to use
enumerate() for tracking indices. Added unit tests for index assignment.
Created demo HTML file demonstrating the full click navigation feature:
- Click span rect -> scroll JSON tree to matching entry
- Highlight target node with yellow background for 2 seconds
- Auto-open ancestor <details> elements
- Smooth scrollIntoView with center alignment
Acceptance criteria:
- PASS: data-span-index attribute added to all spans
- PASS: Click handler scrolls tree to matching node
- PASS: .highlighted class applied for 2 seconds
- PASS: Ancestor details auto-opened before scroll
- PASS: 9 unit tests pass including new span_index test

Implements the span layer renderer for the inspector debug viewer.
Renders SVG outline rectangles for each text span, color-coded by
extraction confidence. Red (< 0.5), yellow (0.5-0.8), and green (> 0.8)
indicate low, medium, and high confidence respectively. Gray indicates
direct extraction without OCR.
Each rect includes data-* attributes for tooltip and click consumption:
- data-text: the extracted text content (XML-escaped)
- data-confidence: confidence score or empty string
- data-font: font name (XML-escaped)
- data-size: font size in points
All 10 unit tests pass. The implementation follows the existing SVG
generation pattern in pdftract-core/src/receipts/svg.rs.
Closes: pdftract-p4vzu

Implement step 5 (white-border padding: 10 px on all sides), wire all
preprocessing steps into the final preprocess(input, ImageSource) ->
GrayImage entry point, and curate fixtures for the three image-source
paths (PhysicalScan / DigitalOrigin / Jbig2).
Changes:
- Add add_border_padding() function: creates (width+20) x (height+20)
image with 10px white border on all sides
- Add preprocess() pipeline orchestrator: applies deskew, contrast
normalization, binarization, denoising, and padding in correct order
- Skip contrast, binarization, and denoising for JBIG2 images

This commit completes Phase 5.2.2 by integrating the pdfium-render path
into serve mode with runtime validation and feature propagation.
Changes:
- Propagate ocr and full-render features from CLI to pdftract-core
- Add full_render parameter to serve mode ExtractParams
- Implement runtime validation in build_options():
* Returns BadRequest if full_render requested but PDFium unavailable
* Falls back to direct compositing if feature not compiled
- Update all three serve handlers to handle Result from build_options()
Acceptance Criteria:
✅ cargo build --features ocr,serve,full-render succeeds
✅ cargo build --features ocr,serve (no full-render) succeeds
✅ Runtime fallback: full_render=true with feature absent uses direct path
Notes:
- Binary size CI gate (140 MB) requires separate CI infrastructure
- Soft-mask regression tests require separate fixture work

The detail field truncation in human.rs only applied to TTY output,
causing lines to exceed 80 columns when piping to cat or using --no-color.
Fix: Apply truncation uniformly across all output modes:
- TTY mode: Use actual terminal width from terminal_size crate
- Non-TTY/--no-color: Assume 80 columns and truncate accordingly
- Detail field max width: term_width - 38 columns
Max line width now exactly 80 characters for all output modes.
Acceptance criteria verified:
- TTY colored table with summary ✓
- Non-TTY plain text, no ANSI ✓
- --json single JSON object ✓
- --json summary counts ✓
- --features list, exit 0 ✓
- --no-color plain text in TTY ✓
- 80-column terminal width ✓
- N/A excluded from human, in JSON ✓

- PASS: --json output parses correctly with jq
- PASS: --features lists compiled features, exit 0

Per ADR-006: stdio and HTTP transports are mutually exclusive because they
have opposite stdout discipline (stdio: JSON-RPC sink; HTTP: log channel).
Changes:
- Add clap ArgGroup with multiple(false) to enforce --stdio XOR --bind
- Default to stdio mode when neither flag is specified
- Change --bind from required String to Option<String>
- Add ADR-006 reference to help text and doc comments

Acceptance criteria:
- pdftract mcp → launches in stdio mode (default)
- pdftract mcp --stdio → launches in stdio mode
- pdftract mcp --bind ADDR → launches in HTTP+SSE mode
- pdftract mcp --stdio --bind ADDR → exits 2 with clap conflict error
- pdftract mcp --help shows mutual exclusivity note

Implements the stdio transport for the MCP server, enabling communication
with local agents (Claude Desktop, Claude Code, Continue, Cursor) over
standard input/output with Content-Length framing.
Core features:
- LSP-style Content-Length framing with \r\n terminators
- JSON-RPC 2.0 message parsing and serialization
- INV-9 compliance: stdout contains only JSON-RPC frames
- Panic hook redirects panics to stderr
- SIGTERM handler for graceful shutdown
- Parse errors return -32700 with id: null, then continue
Acceptance criteria:
- ✅ Piping tools/list with framing produces expected response < 50ms
- ✅ EOF on stdin → clean exit within 100ms
- ✅ Malformed JSON → -32700 error, subsequent requests work
- ✅ No println!/log output to stdout (INV-9 enforced)
- ✅ Panics go to stderr, no partial JSON on stdout
- ✅ SIGTERM → exit 0, SIGINT → immediate non-zero exit
Tests added:
- crates/pdftract-cli/tests/mcp-stdio.rs (8 integration tests, all pass)
- All 49 existing unit tests continue to pass

Two fixes:
1. Hex string lexer now flushes dangling nibble when encountering invalid
characters. For `<4X8Y>`, the X and Y are invalid, so we flush nibble 4
as 0x40, then flush nibble 8 as 0x80, producing `\x40\x80`.
2. Fixed skip_whitespace_and_comments() to properly handle whitespace
after comments. The previous logic only continued looping if the next
byte was `%`, missing cases where whitespace follows a comment.
All 52 lexer tests pass.
