loobric-cli 1.6.0 — cutting data presets

Added

• Cutting data presets (server ≥ 0.13.0; loobric-server docs/PRESETS.md, grilled 2026-08-16): Client.contribute_preset() / Client.list_presets() for the audited contribution door — an F&S recommendation with a source, engineering values only, replace-own on (origin, label). Two new MCP tools, contribute_preset and list_presets (23 tools total): the contribute description teaches the doctrine — origin is the recommender, the agent is stamped as transcriber, raw feed/RPM are never stored, and replace-own is the agent's only revision path (removal stays a human act; there is deliberately no preset delete tool).
