[Repo Assist] Add (*** include-toc ***) directive for inline table of contents in literate F# scripts

Closes #163

Summary

Implements the long-requested in-page table of contents directive for literate F# scripts (.fsx files).

Usage

In any literate .fsx file, place one of these commands where you want the TOC to appear:

(*** include-toc ***)        (* list all headings up to depth 3 (default) *)
(*** include-toc:2 ***)      (* list only H1 and H2 headings *)
(*** include-toc:1 ***)      (* list only H1 headings *)

The directive generates an unordered list of hyperlinks pointing to the heading anchors in the rendered HTML. It requires generateAnchors = true (the default in fsdocs build).

Example

(**
# My Document

(*** include-toc:2 ***)

## Section One

Some content.

## Section Two

More content.
*)

Renders the TOC as links to #Section-One and #Section-Two.

Implementation

• Document.fs: New TableOfContents of maxDepth: int * paragraphOptions: LiterateParagraphOptions case on LiterateParagraph.
• ParseScript.fs: Handles (*** include-toc ***) and (*** include-toc:N ***) commands in transformBlocks, defaulting depth to 3.
• Transformations.fs: New generateTableOfContents function that collects all Heading nodes, computes anchor names using the same algorithm as HtmlFormatting.formatAnchor (including UniqueNameGenerator simulation for duplicate headings), and replaces each TableOfContents paragraph with a ListBlock of DirectLink spans.
• Formatting.fs: generateTableOfContents is called as the first step in transformDocument, before replaceLiterateParagraphs.

Test Status

• Build: ✅ succeeded (0 warnings, 0 errors)
• Tests: ✅ 116/116 passed (FSharp.Literate.Tests)

Done! I've pushed a commit that adds tests and documentation. Here's a summary of what was added — and a bug fix I found along the way.

---

Example

The (*** include-toc ***) command must be placed as a standalone command between (**...*) blocks (not inside one, since ***) would close the preceding (**):

(**
# My Document
*)
(*** include-toc:2 ***)
(**
## Section One

Some content here.

## Section Two

More content here.
*)

This renders an unordered list of links at the position of (*** include-toc:2 ***):

• My Document
• Section One
• Section Two

Use (*** include-toc ***) for the default depth of 3, or (*** include-toc:N ***) to limit to headings up to depth N.

---

What was added

5 new tests in LiterateTests.fs:

1. include-toc parses as TableOfContents with default depth 3
2. include-toc:2 parses as TableOfContents with depth 2
3. include-toc generates anchor links for all headings in HTML output
4. include-toc:N filters out headings deeper than N
5. include-toc handles duplicate heading names with unique anchors

All 121 tests pass.

Documentation added to docs/literate.fsx — a new "Table of Contents" section with a command table and example.

---

Bug fix

I found that generateTableOfContents was only called in the transformDocument path (Formatting.fs) but not in the direct Literate.ToHtml, WriteHtml, ToLatex, WriteLatex, ToPynb, and ToFsx methods. This meant the (*** include-toc ***) command would be silently dropped when using those APIs directly. I've fixed all six call sites in Literate.fs.

@dsyme devil's advocate but do we still needs this since we got the sidebar?
