feat: Add new tools and configurations for Castle platform

Browse Source 
- Introduced `uv.lock` for dependency management with various packages including `pytest`, `colorama`, and `pluggy`.
- Added `pyrightconfig.json` for Python type checking configuration.
- Expanded `recommendations.md` with detailed scaling recommendations and project management strategies.
- Created shared `ruff.toml` for consistent linting across projects.
- Developed `Castle Tools` with various utilities including Android backup, browser automation, document conversion, and search tools.
- Implemented `backup-collect` and `schedule` tools for system administration tasks.
- Enhanced `search` functionality with indexing and querying capabilities using Tantivy.
- Added comprehensive documentation for each tool, including usage examples and installation instructions.

docx2md document.docx
# Output to specific file
docx2md document.docx -o output.md
# Convert from stdin
cat document.docx | docx2md > output.md
```

docx2md: Convert Word .docx files to CommonMark
Converts Word .docx files to CommonMark format (a standardized Markdown specification)
and writes the result to a file with the same basename but .md extension. Also creates
a directory for extracted media assets named <basename>_media/. The markdown content is
also sent to stdout.
This tool uses pandoc with the CommonMark output format and applies additional formatting
to ensure consistent, high-quality markdown output:
- Standards-compliant, well-formed markdown
- Consistent rendering across different Markdown implementations
- Single spacing for list items (removes extra newlines between items)
- Proper blank lines around headings
- No line wrapping by default for easier editing
Usage: docx2md file.docx
docx2md -o output.md file.docx
docx2md --wrap file.docx # Wrap lines at 100 characters
docx2md --wrap 80 file.docx # Wrap lines at 80 characters
Options:
-o, --output FILE Write markdown to FILE instead of <input_basename>.md
-m, --media-dir DIR Store extracted media files in DIR instead of <basename>_media
--wrap [WIDTH] Enable line wrapping at specified width (default: 100)

# Convert single PDF
pdf2md document.pdf
# Output to specific file
pdf2md document.pdf -o output.md
# Convert from stdin
cat document.pdf | pdf2md > output.md
```
### Options
```bash
pdf2md input.pdf [-o output.md]
Options:
input.pdf Input PDF document
-o, --output FILE Output markdown file (default: stdout)
-h, --help Show help message
```
## Features
- Extracts text from PDFs
- Preserves basic formatting where possible
- Handles multi-page documents
- Works with text-based PDFs
- Pipe-friendly output
## Examples
```bash
# Convert and save
pdf2md report.pdf -o report.md
# Convert multiple PDFs
for file in *.pdf; do
pdf2md "$file" -o "${file%.pdf}.md"
done
# Extract and search
pdf2md document.pdf | grep "keyword"
```
## Notes
- Works best with text-based PDFs
- Scanned PDFs (images) require OCR
- Complex layouts may lose some formatting
- Tables are converted to plain text

pdf2md: Convert PDF files to Markdown
Converts PDF files to Markdown format and writes the result to a file with
the same basename but .md extension. Also creates a directory for extracted
media assets named <basename>_media/. The markdown content is also sent to stdout.
The conversion process uses poppler-utils (pdftotext and pdfimages) to extract
text and images from the PDF, then uses pandoc to convert the text to Markdown.
The output preserves as much of the original layout as possible.
Usage: pdf2md file.pdf
pdf2md -o output.md file.pdf
pdf2md -m custom_media_dir file.pdf
pdf2md -o output.md -m custom_media_dir file.pdf
pdf2md file.pdf > another_file.md
Options:
-o, --output FILE Write markdown to FILE instead of <input_basename>.md
-m, --media-dir DIR Store extracted media files in DIR instead of <basename>_media
