…iltering Introduces IntelliStory: given a Storybook build, it diffs against a baseline (explicit or API-predicted) and filters the snapshot set down to the stories a change actually affects, bailing to a full run whenever it can't reason about the change. - cli-command: intelliStory.js (applyIntelliStory, IntelliStoryBailError), lockfileDiff.js and graphTrace.js, exported via the ./intelliStory subpath; adds glob-to-regexp, stream-json and optional snyk-nodejs-lockfile-parser. - client: getStatus() accepts the intelli_story_graph job type, plus getIntelliStorySnapshotNameToCommit() and generateIntelliStoryGraph() hitting the /intelli_story endpoints. Binds createRequire to cjsRequire (not `require`) in intelliStory.js and lockfileDiff.js so the CommonJS-transpiled packaged binary doesn't crash with "_require is not a function", and adds noRequireBinding.test.js as a static regression guard (with the matching .semgrepignore rationale).

…trim comments - intelliStory.js: read the enriched stats file with a single JSON.parse(fs.readFileSync(...)) instead of streaming it with stream-json. The stats payload is only a few MB, so in-memory parsing is simpler and removes the stream-json dependency (and, with it, the last createRequire binding in this file — the packaged-binary footgun now only exists in lockfileDiff.js for the optional snyk parser). - Remove stream-json from cli-command dependencies and the lockfile. - Strip explanatory comments introduced with the feature across the IntelliStory source, tests and trace template. Coverage directives (istanbul ignore), semgrep suppressions (nosemgrep) and the cjsRequire / loadSnyk rationale in lockfileDiff.js are kept — removing them would break the 100% coverage gate and the semgrep scan.

Add tests for the graceful-bail paths added in "apply suggested fixed": - malformed stats-file JSON (validateAndReadStats) - unreadable current lockfile (getAffectedPackages) - unreadable package.json (getAffectedPackages) These run on Node 14 (they bail before the Node>=18 snyk path), fixing the lines/statements coverage-threshold failure on the Node 14 test job.

What
Adds IntelliStory: for a Storybook build, it diffs against a baseline (explicit or API-predicted) and filters the snapshot set down to only the stories a change actually affects, bailing to a full snapshot run whenever it can't safely reason about the change.
This restores the functionality previously reverted in #2310, under the IntelliStory name.
