Long-running upstream skills emit MCP notifications/progress on the SSE
stream. Without forwarding, the gateway swallows them and the MCP
client (Claude Code, Cursor) aborts the tools/call on its idle timer
after ~60s — even though the HTTP stream stays warm.
Gateway now passes the SDK's extra.sendNotification through to
UpstreamAgent.callTool. Any non-response frame with a method but no id
becomes a notification on the client side. Each tools/call carries a
progressToken (client-supplied or request-id fallback) so the client
can correlate.

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).

Adds an "a2amcp" bin (alongside the existing "a2a-mcp" for back-compat)
so that npx -y a2amcp resolves the binary by package name. Without it
npx fell back unreliably when no bin matched.
Also rips the hardcoded "0.1.0" out of cli.ts and gateway.ts and reads
the version from package.json — that was why serverInfo lagged behind
the published tag. Renames the user-facing command in help / error
strings / README from a2a-mcp to a2amcp; the legacy bin stays for
existing scripts.

Local MCP server that exposes any number of deployed A2A agents to
Claude Code, Cursor, Windsurf, and other MCP clients. Reuses the
~/.a2a/credentials.json token written by the Python a2a CLI. Adding
or removing agents is a single ~/.a2a/mcp.json edit.
