release: 0.1.4 — forward cp_jwt + bucket via params._meta

On login the gateway now captures user.id from /v1/auth/login, derives
the user's MinIO bucket (user-<id>-files), and persists both in
~/.a2a/credentials.json. UpstreamAgent.callTool injects
``params._meta = { cp_jwt, cp_url, bucket }`` on every tools/call so
upstream agents see the same caller context the platform orchestrator
provides. Unauthenticated clients omit _meta — back-compat preserved.

Requires a2a-pack with the matching _meta handler in
``a2a_pack/mcp/server.py`` (companion change in apps/a2a).
