Phase 3+4: JS require(), addon system, npm module resolver

CO Copilot committed 2 Jul 2026 · 81328c3f51 · 10 files, +77 −1

- OV.isServer() bridge for realm-aware loading (+ FileExists dir guard).
- js/core/module.js: CommonJS require() over OV.readFile with relative +
  node_modules resolution, package.json main, .js/.json/index, a module
  cache, require.reload() hotloading, and require.load() (mod-root loader).
- js/core/addon.js: GMod-style addon discovery under addons/<name>/ with
  addon.json manifests and shared/server/client entries, realm-selected.
- bridge.js bootstraps require+Addon from disk via OV.readFile+eval (no
  DLL rebuild needed to add these); base/server.js triggers Addon.loadAll
  after all core systems exist so addons can register commands/hooks.
- Demo: js/node_modules/ov-leftpad (npm-style pkg) + addons/hello-world
  that require()s it and registers !hello.

Verified live on the Linux SRCDS server: addon shared+server load and
require("ov-leftpad") resolves and runs (leftpad -> 007) in-engine.
