Protocol versioning policy and schema normalization

[mark-e-deyoung]

Problem

1. protocol/schema_v1.json isn't valid JSON (uses mustache {{}} brackets). No external validator can parse it.
2. Protocol declares version 1.0.0 but has no MAJOR.MINOR policy for backwards compatibility.
3. Old clients have no way to negotiate a supported version range.

Proposed Solution

1. Normalize schema_v1.json to valid JSON
2. Document versioning policy: MINOR adds methods (backwards compatible), MAJOR changes/removes methods
3. Add daemon.protocolVersion method returning supported version range
