fix: repair CI failures (version check + E2E setup)

[NiveditJain]

Summary

• Version consistency check was failing with jq exit code 2 because packages/*/package.json doesn't exist in this single-package repo. Added a [ -f "$pkg" ] || continue guard so the loop is a no-op when no subpackages are present.
• E2E setup was failing because bun run test:npx referenced a script that didn't exist. The test:npx approach (npm pack → install into .test-npx/ → run against @failproofai/<platform> native binary) has been removed since we're not shipping platform binaries. Replaced with a direct bun build of the public API entry point (src/index.ts → dist/index.js), and E2E tests now invoke the binary from the repo source via bun.

Test plan

• CI quality job passes (version check no longer fails on missing packages/)
• CI test-e2e job passes (Build E2E fixtures step + E2E Hook Tests both succeed)
• bun build src/index.ts --outdir dist --target node --format cjs && bun run test:e2e passes locally

📝 Walkthrough

Walkthrough

The pull request refactors the E2E testing infrastructure from a packaging-and-installation model using bun run test:npx to a direct binary execution model. This includes updating CI workflows, test helpers, documentation, and introducing a new public API entry point that re-exports key utilities.

Changes

Cohort / File(s)	Summary
CI and E2E Test Infrastructure .github/workflows/ci.yml, __tests__/e2e/helpers/hook-runner.ts	Updated CI workflow to skip non-existent package.json files and suppress jq errors. Modified hook runner to execute fixed binary bin/failproofai.mjs via bun invocation instead of platform-specific npm-installed binaries, and simplified error messaging.
E2E Test Configuration __tests__/e2e/hooks/builtin-policies.e2e.test.ts	Updated test setup instructions to build CommonJS distribution directly via bun build instead of running bun run test:npx.
Documentation docs/testing.md	Revised E2E test setup documentation to reflect new model: pre-building dist/ directory and running tests directly, removing persistent .test-npx/ directory approach.
Public API Entry Point src/index.ts	Added new module that re-exports hook utilities (customPolicies, getCustomHooks, clearCustomHooks), policy helpers (allow, deny, instruct), and policy-related types from internal modules.

Poem

🐰 The binary hops with grace so fleet,
No packaging maze to complete!
Direct invocation, dist so neat,
A cleaner path makes testing sweet,
Public APIs now polished bright. ✨
