Afraid of crashing after installing the plug-in

Key features

• C1 files integrityfiles whitelist vs actual lib product, missing chunk → error
• The child process completes boot() of the whole tree (webserver port offset is 0, zero conflict with the running backend), the base assertEntriesActivated asserts that each enabled plug-in is activated, and the timeout is 90s to catch hang.
• The iron rule of isolationonly readFile, never import / require / execute plug-in code.
• Root cause chainctx.plugin(SandboxedFileSystem) is asynchronous, and then localCtx.fs is fetched synchronously immediately and cannot get the service (the key of the isolation scope does not match) → cannot get property "fs" without inject.
• C2 dependency statementlink: with runtime dependencies / file: with harness peer
