ToolAhead 0.6.0

Hooks-only by default: toolahead init now replaces nothing — your agent keeps its native tools, while learning, service pre-warming, route warming, and transparent Bash replay ride on lifecycle hooks. The ToolAhead MCP tools (Read/Search replay hits) are an explicit opt-in via --replay-tools (--strict implies it).

The readiness guarantee for declared external commands moved into the PreToolUse hooks of Claude Code, Codex, and Antigravity: matching native shell commands wait for their services and are denied with an actionable reason only when a trusted config's service stays down. Fail-open everywhere else; TOOLAHEAD_ENSURE_WAIT=0 disables the wait.
