feat(web): opt-in session replay via @openpanel/web/replay (#414)

[grootbro]

Summary

• Fixes #414: @openpanel/web no longer import('./replay')s from the main entry, so rrweb is not emitted for apps that never enable session replay.
• New subpath @openpanel/web/replay exports startReplayRecorder. NPM consumers pass it as sessionReplay.recorder.
• Script-tag / IIFE builds are unchanged: they still load op1-replay.js from the CDN when sessionReplay.enabled is set.
• Docs and publish exports updated for the replay subpath.

Test plan

• NPM app without @openpanel/web/replay import: bundle contains no rrweb / replay chunk
• NPM app with recorder: startReplayRecorder and enabled: true: replay chunks send
• NPM with enabled: true but no recorder: console warning, no crash
• Script-tag op1.js with sessionReplay: { enabled: true }: still loads CDN op1-replay.js
• CI: packages/sdks/web resolveSessionReplayRecorder tests pass

Summary by CodeRabbit

• New Features

  • Added a dedicated @openpanel/web/replay entry point for npm installations.
  • npm integrations can provide the session replay recorder explicitly through configuration.
  • Script-tag integrations continue loading the recorder automatically.
  • Applications that do not import the replay entry point avoid shipping replay functionality in the main bundle.

• Documentation

  • Updated setup instructions and configuration references to explain the required npm recorder import and installation-specific behavior.

📝 Walkthrough

Walkthrough

The web SDK now exposes @openpanel/web/replay and accepts its recorder through sessionReplay.recorder. Library builds no longer dynamically import replay code. IIFE builds retain CDN loading. Publishing, tests, and documentation reflect the new setup.

Changes

Session replay opt-in

Layer / File(s)	Summary
Recorder contract and entry points packages/sdks/web/src/resolve-replay-recorder.ts, packages/sdks/web/package.json	Adds recorder types, resolution logic, and the ./replay package export.
SDK startup and recorder loading packages/sdks/web/src/index.ts, packages/sdks/web/src/resolve-replay-recorder.test.ts	Accepts an injected recorder, preserves replay chunk delivery, loads the CDN recorder for IIFE builds, and tests each resolution path.
Build, release, and test wiring packages/sdks/web/tsup.config.ts, tooling/publish/publish.ts, packages/sdks/web/package.json, packages/sdks/web/vitest.config.ts	Builds replay as a separate entry, publishes its export metadata, and configures Vitest execution.
Consumer configuration documentation apps/public/content/docs/(tracking)/session-replay.mdx, apps/public/content/guides/session-replay.mdx	Documents the recorder import for npm installations and the automatic script-tag behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 399fe

Session replay is now opt-in for package consumers while preserving the existing script-tag replay behavior. No concrete current-head merge-blocking risk is identified.

- Line 98: Update the session replay guide to remove the obsolete claim that the
npm package dynamically imports the replay module. Document the required
explicit `@openpanel/web/replay` import and sessionReplay.recorder usage, and
qualify the overview statement for npm users so they understand replay will not
start without the recorder.
