#376 docs(changelog): record the uninstall + parity wave (#373, #374, #375)

[Anonymous]

Originally created by: fu351

Three Unreleased entries for today's contributor wave: the gated doberman uninstall command (#375, closes [#250]), the MCP-proxy output-scan parity cell (#374, closes [#332]), and the uninstall-ordering docs warning (#373). Changelog only, no code.

• [x] Any guardrail/learning change is raise-only (N/A)
• [x] Every BLOCK/AUTH carries reason codes + a human explanation (N/A)
