v1.12.0

• add --auto-approve and repeatable --approve-tool <tool> to preconfigure agent-level MCP tool approval. Capability-gated per client and mapped to each client's native mechanism: Codex writes approval modes to config.toml (tools.<name>.approval_mode = "approve", or default_tools_approval_mode for all tools); Claude Code writes permission allow rules (mcp__<server>__<tool>, or mcp__<server> for all tools) to a separate settings file (.claude/settings.local.json for project installs, ~/.claude/settings.json for global) while keeping the MCP server entry clean. Agents that don't support auto-approval have it dropped with a warning. Co-authored with @RhysSullivan (#32)
• update Antigravity configuration to the latest shared MCP config path at ~/.gemini/config/mcp_config.json, used by Antigravity, Antigravity IDE, and Antigravity CLI.
