fix(telemetry): drop profile field [skip-runtime-e2e] (#170)

* fix(telemetry): drop profile field — collides with governance env var

The v1 telemetry schema added a `profile` payload field sourced from
`AXONFLOW_PROFILE`. That env var was already in use for governance
enforcement (allowlist `dev|default|strict|compliance`, ADR-036), and
the v1 telemetry validator only accepted `dev|prod|unknown` — so any
customer setting `AXONFLOW_PROFILE=strict` or `=compliance` for
governance had their telemetry pings rejected with HTTP 400.

Drop the field entirely. The `deployment_mode` dimension already
carries the topology signal `profile` was meant to add, and
`AXONFLOW_PROFILE` reverts to its single governance-only purpose.

- Remove env-var read + payload field + doc comment in TelemetryReporter.
- Tests: assert `profile` is ABSENT on the wire (stronger than the
  previous `equals("unknown")` assertions; actively guards against the
  field re-appearing).
- Bump pom.xml + the two example poms to 8.0.1.
- CHANGELOG entry under [8.0.1].
