Bump SDK version to 0.9.0 (#5541)

CLAUDE: Minor bump for the new `agent_map` `return_table` feature added
in #5531.

Updates all 11 version locations across `futuresearch-python/`:

- `pyproject.toml` (source of truth)
- `.claude-plugin/{plugin,marketplace}.json`
- `gemini-extension.json`
- `CITATION.cff` (+ `date-released: 2026-04-24`)
- `README.md` BibTeX block
- `futuresearch-mcp/{pyproject.toml,server.json,manifest.json}` (+
`futuresearch>=0.9.0` floor)
- `stubs/everyrow/pyproject.toml` (+ `futuresearch>=0.9.0` floor)
- `stubs/everyrow-mcp/pyproject.toml` (+ `futuresearch-mcp>=0.9.0`
floor)
- `uv.lock` regenerated

## Test plan
- [x] `uv run pytest tests/test_version.py` — 2 passed
- [x] `rg --hidden "0\.8\.4"` — no remaining hits
- [ ] After merge: confirm `sync-futuresearch-python.yaml` mirrors to
the public repo and the downstream PyPI publish picks up 0.9.0
