v0.8.0

Changed (BREAKING)

• Requires MCP SDK 2.0 (mcp[cli]>=2.0,<3.0). mcp.server.fastmcp no longer exists in 2.0; the server is now built with MCPServer and reports its package version in the stdio handshake.

Fixed

• undo apply works from the CLI. Every write tool is imported lazily inside its own CLI command, so a CLI-driven undo ran in a process where the inverse tool was never registered and failed with "inverse tool is not registered" — for every write tool. Only the MCP entry point, which imports the whole server, worked. Found while live-verifying against a real cluster.
• An undetermined outcome is audited unknown, not ok. The harness only classified a result as undetermined when the payload also carried an error key, so a write that looked successful but had not been confirmed was recorded as a success.
• OSD host leaked a Python dict repr and crushWeight was always null. Live-verified against Ceph 18 (reef): /api/osd returns host as a CRUSH bucket dict, not a string, and crush_weight is nested under tree. Both now read the real shape.
• crushWeight falls back to the tree only when the key is truly absent. .get(k, default) does not fire its default for a key that exists with a null value, so a build sending crush_weight: null at the top level would have reported null while the real number sat in tree. Uses is not None rather than truthiness, so an explicit 0 — a real CRUSH weight for a draining OSD — survives.
