fix(llmstxt): include TypeScript API docs in llms.txt

[strands-agent]

Description

Fixes the empty TypeScript API section in llms.txt by using a recursive glob pattern to include all TypeScript API documentation files.

Problem

The current llms.txt configuration uses docs/api-reference/typescript/*.html which only matches files in the root directory. However, typedoc generates documentation into subdirectories:

• classes/ - Agent, Tool, Message classes
• types/ - TypeScript type definitions
• interfaces/ - Interface definitions
• functions/ - Exported functions

This results in an empty TypeScript API section in llms.txt, blocking AI coding assistants (Claude Code, Cursor, Windsurf) from helping users write TypeScript code.

Solution

Change the glob pattern from *.html to **/*.html to recursively match all HTML files generated by typedoc.

Before

TypeScript API:
  - docs/api-reference/typescript/*.html  # Only matches 2 files in root

After

TypeScript API:
  - docs/api-reference/typescript/**/*.html  # Matches all 123 HTML files

Related Issues

Fixes #426

Type of Change

Bug fix

Testing

Verified locally:

1. Generated TypeScript docs with npm run docs:ts
2. Confirmed 123 HTML files exist across subdirectories
3. Verified the glob pattern change matches all files
