LLeMbas CLI 1.0.0
The first public release of LLeMbas CLI: a terminal coding agent and project manager for any LLM
API, with permission modes, git snapshots, memory and skills, knowledge bases, MCP, voice, and a
link to a LLeMbas instance whose web UI can work its sessions too. Signed Linux binaries for x64
and arm64.

// The account on a LLeMbas instance: /v1/usage for the status bar and /usage, the
// personalization read from /v1/me/personalization in place of the local keys and written back by
// /settings, and the account's library as the default when the login may read it. A fake instance;
// the instance index, keys and caches are removed after each test (the suite shares one home).
