v0.2.0 — remove vendored fork, upstream login feature

- Delete vendor/schwab-scraper/ (now fetched at CI build time)
- Delete schwab_mcp_custom/ package (LoginManager moved into server.py)
- server.py: add inline LoginManager with env-configurable rate limits
- server.py: orchestrate login safety checks at MCP layer, not in scraper
- Dockerfile: restore vendor-based build with fresh upstream checkout
- pyproject.toml: bump mcp>=1.27.0, playwright>=1.54.0
