Patch release for the bundled RLM integration.\n\n- Integrated upstream Dach-Coin/rlm-tools-bsl into the current MCP facade as proxied RLM tools.\n- Set BSL Language Server and RLM_TOOLS_BSL_VERSION compose defaults to latest.\n- RLM_TOOLS_BSL_VERSION=latest now resolves through PyPI at image build time, while explicit pinned versions remain supported.\n- Switched runtime and BSL LS downloader stages from debian:bookworm-slim to debian:trixie-slim. Java 21 now comes from Debian 13 as openjdk-21-jre-headless, without the external Adoptium/bookworm APT repository.\n- Verified rebuilt container: Debian 13.5 trixie, BSL LS 1.0.2, Java 21.0.11, Python 3.13.5, rlm-tools-bsl 1.26.0, container healthy.\n- Fixes #1.
