PR Review: README typos, formatting, and consistency fixes

Summary

Documentation-only PR that adds a Table of Contents and fixes several typos and formatting issues in the README. Single commit, single file changed (+27/-9).

Changes Reviewed

Table of Contents (lines 10–21): Adds a well-structured ToC linking to existing sections. Anchor links match the actual headings. Looks correct.

Code fence language tags: Several bare ``` blocks changed to ```sh — good for syntax highlighting consistency.

Typo fixes — all correct:

• "The are" → "There are"
• "namspace" → "namespace"
• "a a stream" → "a stream"

Link fix: Chart repo link updated from master to main branch — matches the actual default branch.

Inline comment moved to note block: The // Not required if running with --control-loop inline comment in a shell code block is moved to a proper > **Note**: blockquote above the code. This is a good fix — shell comments use #, not //, so the original was misleading.

Added descriptions:

• Brief description added under "API Reference" heading.
• Brief description added under "NATS Boot Config" heading.
  These are helpful for readers scanning the document.
