Addresses Greptile's review on #2994:
- missing-dependency.js no longer hardcodes a second copy of the four
runtime dependency versions; it reads them from package.json's
dependencies field instead, so the two can't silently drift apart.
describeMissingDependencyError() still recognizes a tracked
dependency even if package.json can't be read for some reason,
just without a version-pinned install command in that case.
- The regression test now asserts no ancestor directory of its
temp fixture has a node_modules, so a stray one wouldn't let
Node resolve ajv/sql.js from there and mask what the test is
actually meant to exercise. Also copies package.json into the
fixture, matching a real plugin-marketplace git clone and what
the version-lookup above now needs.
install-plan.js and install-apply.js both require ./lib/install/config at
load time, and that module required ajv unconditionally at the top of the
file even though ajv is only actually used when validating an
ecc-install.json. When ECC is installed via the Claude Code plugin
marketplace, the marketplace directory is a bare git clone with no
node_modules, so requiring ajv crashes commands like --list-profiles that
never touch install-config validation at all.
Same root cause in scripts/lib/control-pane/state.js: sql.js and
@iarna/toml were required at module scope even though they are only used
inside openSqlDatabase() and readTomlConfig(), so control-pane.js --help
crashed too.
Make both requires lazy so they only load when the feature that actually
needs them runs. For the case where ajv/sql.js/js-yaml/@iarna-toml is
genuinely needed and still missing, add a small helper that turns the raw
MODULE_NOT_FOUND into an actionable message naming the package and the
install command, instead of a stack trace (install-apply.js) or, worse, an
unhandled crash with a usage banner tacked on that reads like a bad
argument (install-plan.js, control-pane.js). Applied the same helper to
memory-mcp.mjs, where ajv is genuinely load-bearing (it compiles every MCP
tool's JSON schema up front) so it can't be made lazy the same way.
Added a regression test that copies just scripts/, schemas/, and
manifests/ into a directory with no node_modules anywhere above it in the
filesystem, which reproduces the plugin-marketplace install exactly, and
asserts install-plan.js and control-pane.js still work.
