v1.0.0 — work primitives, brain FS, web search

First 1.0.0 of the open Unison brain client (SDK + CLI + MCP). It covers the
complete /v1 surface so any coding agent — via the SDK, the unison CLI, or
the MCP server — has the same capabilities.

Added

• Work primitives — the work domain (folders, documents, tables, records,
  views) and the typed work-operations DSL via u.work.apply({ operations }),
  plus query / search / inspect / tree. CLI unison work …; MCP work_* tools.
• Brain filesystem — read / write / list / search / grep over
  documents; editDoc is a surgical, atomic server-side str_replace. CLI +
  brain_* MCP tools.
• Mail — mail.draft opens an editable draft for human review (a new email,
  or a reply within an existing thread).
• Web search — research.search (SDK), unison web-search (CLI), and the
  web_search MCP tool — the client's route to the open web.

Breaking

• The crm, tasks, and workspace SDK domains are removed and folded into
  work. Pin @unisonlabs/sdk@^0.2 if you still target a pre-/v1/work server.

Packages (all 1.0.0): @unisonlabs/sdk, @unisonlabs/cli, @unisonlabs/mcp.
