Trim enabled models and switch work host to claude-sonnet-5

[boga]

Why

Model lineups drift over time — home had a long list of opencode-go
variants no longer in use, and work was still pinned to
claude-sonnet-4-6 in three places while claude-sonnet-5 is now the
model of choice.

Approach

Kept the change scoped to host_vars so it's per-machine: home only
needed enabledModels trimmed, work needed both enabledModels updated
and every claude-sonnet-4-6 reference (pi_plannotator_executing_model,
scout, worker) bumped in lockstep to avoid pointing subagents at a
model no longer in enabledModels.

How it works

• host_vars/home/vars.yml: enabledModels trimmed to openai-codex/gpt-5.5,
  dropping unused opencode-go/* entries.
• host_vars/work/vars.yml: enabledModels swaps claude-sonnet-4-6 for
  claude-sonnet-5 and drops gemini-3.1-pro-preview/gemini-3.5-flash;
  pi_plannotator_executing_model, scout, and worker model refs updated
  to claude-sonnet-5 to match.

📝 Walkthrough

Walkthrough

This PR updates AI agent model configuration in two host_vars files. It trims the home host's enabledModels to a single entry and switches the work host's executing model, subagent overrides, and enabledModels list from claude-sonnet-4-6 to claude-sonnet-5, removing Gemini entries.
