revert: undo accidental inclusion of non-doc changes in 60eedce

Commit 60eedce was meant to only remove the hero image from
introduction.mdx, but accidentally included changes to:
- pyproject.toml
- sec_edgar_mcp/core/client.py
- sec_edgar_mcp/server.py
- sec_edgar_mcp/tools/filings.py

This commit restores those files to their state before 60eedce,
keeping only the intended documentation change.
