chore: add changeset for v0.1.0 release

[LiranCohen]

Summary

Adds a changeset to trigger the first functional npm release (v0.1.0).

The currently published @enbox/memoryd@0.0.1 contains only placeholder stubs from the initial scaffolding — the CLI entry point is 149 bytes and does nothing. This is why memoryd --help, memoryd auth login, and all other commands produce zero output when installed via npm install -g.

What v0.1.0 includes

• Full CLI with all commands (auth, init, serve, fact, task, mcp, compact, audit, revoke)
• MCP server with 12 tools, 5 resources, 2 prompts
• 3 DWN protocols (memory/v1, task-graph/v1, memory-audit/v1)
• SQLite sidecar with hybrid vector+FTS5 search
• Shared Enbox identity management (~/.enbox/profiles/)
• Memory compaction engine
• Agent consent management

Verification

Built locally and verified npm pack --dry-run includes 192 files (vs 82 in the broken 0.0.1), with dist/esm/cli/main.js at 8.8KB (vs 149B).
