docs(manual): fix P0 copy and layout issues

[thinksyncs]

Summary

• Fix the first batch of manual P0 issues around copy-paste safety, figure accuracy, table readability, and reference URL hygiene.

Changes

• Normalize Ch.2 demo shell comments and replace the multitask showcase with task-specific artifact panels.
• Clarify the deployment flow figure with artifact/runtime/validation layers.
• Convert Ch.9 benchmark and runtime/license matrices into readable task/category lists.
• Remove the tracked arXiv URL parameter and fix Ch.12 LaTeX-safe code/path rendering.

Testing

• /opt/homebrew/bin/python3 tools/validate_tool_manifest.py --manifest tools/manifest.json --require-declarative
• /opt/homebrew/bin/python3 -m unittest tests.test_packaged_tools_manifest tests.test_manifest_docs_references
• make -C manual pdf
• git diff --check
• rg scan for smart quotes, en-dash CLI flags, python3tools, tracked URL params, and stale percent shell comments
• pre-push hook: ruff, focused unit tests, offline smoke, real-image scenario preflight

Notes

• Remaining manual overhaul tasks stay tracked in bd, including broader LaTeX escape cleanup and Ch.4 restructuring.

In the pose6d task card, “compares backend predictions artifacts” reads like a grammatical typo. Consider changing to “prediction artifacts” to match the other entries (e.g., “depth artifacts”).
