fix: ensure query media keyword filters apply without vectors

[Teagan42]

What

• add keyword-specific prefetch filters to query_media so vector prefetches respect keyword payload constraints
• ensure keyword-only queries reuse those conditions as the main filter when no vector prefetch occurs
• extend the server tests to validate that keyword filters propagate to both prefetch and keyword-only requests
• bump the project version metadata

Why

• ensure dense and sparse prefetches narrow candidates when keyword payload filters are supplied and still scope keyword-only queries when no vector prefetch runs

Affects

• mcp_plex.server.query_media
• server test suite
• project version metadata

Testing

• uv run ruff check .
• uv run pytest

Documentation

• not needed
