Module persona 

Context personas (persona-spec-v1).

A persona is a declarative bundle that shapes the whole context surface for a domain — not just coding. It composes:

• tool surface (a ToolProfile: built-in tier or custom list),
• default read-mode,
• compressor + chunker (names from the extension registry, 12.9),
• intent taxonomy (the task labels meaningful for the domain),
• sensitivity floor (minimum classification to enforce).

Personas build on the existing tool profiles and are selectable per workspace/channel/session via config (persona = "…") or the LEAN_CTX_PERSONA env var. The built-in coding persona reproduces today’s default behavior; further presets are added in 12.16.
