[audit/high] Categorize entries and add table of contents

[Displacedtex]

Priority: High

Problem

README.md contains 103 rows in one flat Sr No | Name | Link table. There is no categorization and no anchor-linked TOC. Mobile users especially struggle to scan.

Recommendation

Group entries into sections, each with an anchor:

• Computer Vision
• Natural Language Processing
• Time Series
• Reinforcement Learning
• MLOps / Production
• Papers-with-Code
• Datasets
• Courses / Tutorials
• Meta-lists (awesome-* links)

Add a TOC at the top with per-category counts (e.g. Computer Vision (23)). Per-category counts also surface coverage gaps — useful when growing the list.

Acceptance criteria

• TOC at top of README with clickable anchors.
• Every entry lives under a category heading.
• Counts are accurate as of the last edit.
