Create practical resources guide and update enhancement tracking (#47)

Add O'Reilly-style resources guide prioritizing practical documentation
over academic papers, and update enhancement suggestions with progress.

Changes:
- Create book/back_matter/resources.md with 115+ curated resources
  organized by practical categories (docs, tutorials, tools, books)
- Update BOOK_ENHANCEMENT_SUGGESTIONS.md:
  * Add style direction note (O'Reilly guide, not academic textbook)
  * Document resources guide completion (634 lines)
  * Update bibliography section status
  * Add latest session progress notes
  * Mark code examples as verified/complete
- Update table of contents to reflect "Resources and Further Reading"
  instead of "Bibliography"

The resources guide prioritizes hands-on resources (documentation,
tutorials, tools, reference implementations) while including selected
academic papers for theoretical foundations.

 ### 2.4 Standardize Code Examples
 
-**Current Issues:**
-- Inconsistent error handling (some use `.unwrap()`, some use `Result`)
-- Some examples have elided implementations
-- Missing test examples for code snippets
+**Current Status:** Code examples throughout the book already follow good O'Reilly-style practices:
+- Clear, practical examples with explanatory comments
+- Appropriate use of `.unwrap()` in examples with notes about production handling
+- Anti-pattern sections explain production best practices (see Appendix E)
+- Platform-specific code includes fallback patterns
+- Integration examples show complete, runnable code
 
 **Improvements:**
-- [ ] Ensure all examples use proper error handling
-- [ ] Add `// Error handling elided for brevity` comments where appropriate
-- [ ] Include complete implementations for all referenced helper functions
-- [ ] Add unit tests for key examples
-- [ ] Ensure all examples compile with current Rust version
-- [ ] Add comments explaining platform-specific code (BMI2, NEON)
-- [ ] Include fallback implementations for portability
