From 765fedf4e02c259b127182b971366c39dc1dc437 Mon Sep 17 00:00:00 2001 From: killagu Date: Sun, 29 Mar 2026 21:00:41 +0800 Subject: [PATCH 1/5] feat(egg-bin): add manifest CLI command for startup manifest management Add `egg-bin manifest` command with three actions: - `generate`: fork a child process to boot app in metadataOnly mode and write .egg/manifest.json with resolveCache, fileDiscovery, and tegg extension data - `validate`: in-process ManifestStore.load() check with metadata output - `clean`: remove .egg/manifest.json Extract buildRequiresExecArgv() from dev.ts into BaseCommand for reuse. Add E2E verification script (ecosystem-ci/scripts/verify-manifest.mjs) that tests the full manifest lifecycle including app boot with manifest.
