Implement the --receipts CLI flag accepting "off" | "lite" | "svg" with default "off".
Thread the ExtractionOptions.receipts field through the extraction pipeline so that
receipts are generated for spans and blocks based on the selected mode.
Changes:
- CLI: Added --receipts flag with clap value_parser for runtime validation
- CLI: Added feature check for SVG mode (requires 'receipts' feature)
- MCP tools: Added receipts field to ExtractArgs, ExtractTextArgs, ExtractMarkdownArgs
- MCP tools: Added build_extraction_options() to parse receipts mode
- Core: Added extract.rs module with extract_pdf(), extract_page(), generate_receipt()
- Core: Added ExtractionOptions with ReceiptsMode enum (Off/Lite/SvgClip)
- Core: Added receipts feature flag to Cargo.toml

- Add value_parser = ["off", "lite", "svg"] to --receipts CLI flag for clap validation
- Add receipts field to ExtractTextArgs and ExtractMarkdownArgs in MCP tools args
- Add ExtractionOptions and ReceiptsMode to pdftract-core (options.rs module)
- Expose options module in pdftract-core/lib.rs
The CLI now validates receipts mode at parse time with helpful error messages.
MCP tools accept receipts argument matching the schema defined in sibling 6.7.5.
ExtractionOptions struct provides the threading mechanism for the extraction pipeline.
Acceptance criteria:
- PASS: CLI validates --receipts values (off/lite/svg only)
- PASS: CLI shows proper help text with possible values
- PASS: ExtractionOptions serializes for HTTP/MCP transport
- PASS: MCP tools args have receipts field
- WARN: Full extraction implementation pending (deferred to extraction beads)

Changes from Phase 6.7 child beads that were not committed earlier:
- Add subtle dependency for constant-time token comparison
- Add root directory for path-traversal protection in HTTP+SSE transport
- Update MCP server state to support --root flag
- Minor fixes and improvements across MCP modules
These changes support the 7 closed child beads:
