Custom tool loading crashes on transient dependency install failures #13784

Problem

Config.waitForDependencies() runs bun install once and silently swallows failures. On Windows, transient file locks can cause this to fail.
ToolRegistry.getCustom() directly imports each tool module without isolation — one broken custom tool crashes loading for all custom tools.

Expected behavior

Transient dependency install failures should be retried before giving up
A broken custom tool module should not prevent other tools from loading

Environment

Primarily affects Windows (file lock contention during bun install)
Also affects any environment where a custom tool module has a syntax/runtime error
