Export the agent e2e suite as a release bundle for downstream repos

[ling-senpeng13]

What

Packages the agent e2e suite (e2e/) into a self-contained, version-stamped tarball — conductor-ai-e2e-typescript-<version>.tar.gz — attached to every GitHub release, so downstream repos (e.g. orkes-io/orkes-conductor) can pin the e2e suite to the exact javascript-sdk release they run against. Replaces the agentspan-sdk-e2e-typescript-* bundles formerly cut from agentspan-ai/agentspan (whose pinned conductor-agent-sdk npm package was never published, so they couldn't run). Mirrors conductor-oss/java-sdk#128.

• scripts/package-e2e-bundle.sh — stages e2e/ verbatim (suites already import by package name, so no rewriting) + a standalone package.json pinning @io-orkes/conductor-javascript@<version> from npm + a jest config with no src aliases (the published package must resolve) + run.sh + README. isolatedModules: true keeps ts-jest transpile-only, matching the repo root tsconfig — suites dynamically import optional provider SDKs inside try/catch and skip when absent.
• scripts/test-package-e2e-bundle.sh — static validator (file parity, version pin, no src aliases, junit reporter wired; no network).
• .github/workflows/release-agent-e2e-bundle.yml — packages, validates, generates sha256 sidecars, uploads to the release; same triggers as release.yml, plus workflow_dispatch to attach bundles to existing releases (first target: v4.0.0-rc1).

Validation

• static validator green
• bundle installs the published @io-orkes/conductor-javascript@4.0.0-rc1 from npm and resolves the /agents subpath export
• full bundle run vs conductor-oss 3.32.0-rc.8 (real LLM calls): 25 suites — 23 passed, 2 skipped (optional-service suites skip gracefully), 0 failed after adding zod-to-json-schema to the bundle devDeps (the SDK's tool() Zod→JSON-Schema fallback needs it with zod v3)
