When markitdown is installed but a format-specific sub-dependency is
missing (e.g. pdfminer-six for PDF), translate the raw traceback into
a DependencyMissingError with the correct install command.

Always register MarkitdownExtractor so it overrides specialized extractors
for all its extensions. When markitdown-no-magika is not installed, users
now see the correct install hint instead of the old pymupdf4llm message.

Uses markitdown-no-magika (lighter fork without magika/onnxruntime) to
handle PDF, HTML, DOCX, PPTX, XLSX, XLS, CSV, JSON, and XML files.
Specialized extractors (pymupdf4llm, markdownify) remain as fallbacks
when markitdown is not installed.

Introduces a new `markitect/proxy/` module with pluggable extractors that
convert non-markdown sources (PDF, HTML) into tracked markdown proxy files.
Proxy files preserve origin metadata (path, checksum, timestamp) so they
can be kept in sync when the original changes.
CLI commands: `proxy create`, `proxy update`, `proxy status`, `proxy extractors`.
Built-in extractors: PDF (pymupdf4llm), HTML (markdownify), Markdown (built-in).
