* feat(mcp): distribution-channel client marker in MCP telemetry
Record an optional client marker on mcp.tool_called, mcp.tools_list_called
and mcp.resource_read events so per-channel adoption (e.g. the OpenClaw
skill) is measurable in event_log (180-day TTL).
- Server reads X-Gnubok-Client header, falling back to a ?client= query
param on the endpoint URL. Sanitized ([A-Za-z0-9._-]{1,64}, lowercased),
telemetry-only — same trust level as Mcp-Session-Id, never auth.
- The query param works with the already-published gnubok-mcp 1.0.1 via
GNUBOK_URL, so no npm release is required to start measuring.
- Bridge 1.1.0 additionally forwards GNUBOK_CLIENT as X-Gnubok-Client.
OAuth-path attribution via DCR client_name is a possible follow-up — DCR
is stateless today, so client_name isn't recoverable at token time.

* fix(mcp): address PR #706 compliance findings
- ropa.yaml: declare the distribution-channel marker in the mcp.telemetry
processing activity (GDPR Art. 30 — RoPA was drifting from actual flow)
- bridge: mirror the server's allow-list on GNUBOK_CLIENT so an invalid
value degrades to no header instead of fetch() rejecting every request
- lib/events/types.ts: annotate client as client-supplied/telemetry-only
- test: pin that the allow-list runs on the percent-decoded ?client= value
