Brent VatneandClaude Opus 5.5 3af45ebf84 feat: default to Claude Opus 5.5 and install Claude Code 2.1.280 ...

The scaffolded default model moves from anthropic/claude-sonnet-5 to
anthropic/claude-opus-5-5, and the security and coordinator pins move from
claude-opus-5 to claude-opus-5-5. Claude Code 2.1.212 rejects Opus 5.5
("version 2.1.280 or newer is required"), so every workflow template installs
2.1.280.

The CLI bump re-checked the deny list: 2.1.280 adds ListAgents, which is now
in ALWAYS_DENIED_TOOLS; every other denied name stays hidden.
