Codex: implement Holmes CLI skeleton and language surface validator

[mdheller]

Mission

Turn Holmes from product doctrine into a working CLI/service controller skeleton.

Context

PR #1 bootstraps Holmes as the language intelligence fabric. This issue adds the first executable surface.

Required commands

Implement a holmes CLI with:

holmes --version
holmes doctor
holmes self-test
holmes emit-evidence
holmes analyze <path>
holmes search <query>
holmes graph <path>
holmes govern <path>

Behavior

• doctor validates examples/holmes-surface.json and reports integration readiness.
• analyze accepts a text file and emits deterministic JSON with basic counts, language-surface placeholder metadata, and evidence fields.
• search, graph, and govern may be deterministic stubs that report delegation targets and required integrations.
• emit-evidence emits tool version, platform, repo, and validated Holmes surface refs.

Product boundaries

• Sherlock Search remains the discovery/retrieval engine.
• Holmes orchestrates language intelligence but does not embed every model or dataset.
• Local lab execution belongs in SociOS-Linux/nlplab.
• Platform runtime graduation belongs in SocioProphet/prophet-platform.

Acceptance criteria

• make validate passes.
• make build produces a local holmes binary or executable.
• holmes --version, holmes doctor, and holmes analyze examples/sample.txt work.
• Tests cover example validation and deterministic analyze output.
• README documents Homebrew future path: brew install holmes and façade path: prophet holmes ....

Out of scope

• Do not implement full retrieval engine here.
• Do not call remote models.
• Do not add heavyweight NLP dependencies in this first pass.
• Do not duplicate Sherlock Search internals.
