-- Migration 016: Version Manager & Upstream Proxy tables
-- 
-- Adds two tables for CLIProxyAPI integration:
--   version_manager       — binary lifecycle management for CLI tools (CLIProxyAPI, etc.)
--   upstream_proxy_config — per-provider routing mode (native vs CLIProxyAPI vs fallback)

-- --------------------------------------------------------------------------
-- Table: version_manager
-- Tracks installed versions, process state, and update settings for
-- externally managed CLI tools (initially CLIProxyAPI).
-- --------------------------------------------------------------------------

  auto_update       INTEGER NOT NULL DEFAULT 1,    -- 1 = auto-update enabled
  auto_start        INTEGER NOT NULL DEFAULT 0,    -- 1 = start with OmniRoute

  config_overrides  TEXT,                           -- JSON blob for CLIProxyAPI config overrides

  created_at        TEXT NOT NULL DEFAULT (datetime('now')),
  updated_at        TEXT NOT NULL DEFAULT (datetime('now'))
);

-- Table: upstream_proxy_config
-- Per-provider routing configuration for CLIProxyAPI passthrough mode.
-- Determines whether each provider uses OmniRoute's native executor,
-- delegates to CLIProxyAPI, or uses fallback (native first, then CLIProxyAPI).
