fix: video recorder timer keeps running after leaving the room - #43589
Leaving a room while a video message is recording unmounts the recorder dialog, but the one-second clock timer keeps running and the recording activity is never stopped.
The timer id is now kept in a ref and cleared on unmount, and UserAction.stop is called for that room. Cancel and Send use the same stop path.
Allow the camera and click Record so the timer starts counting.
Switch to another channel without clicking Cancel or Send.
The timer should stop, and another user should no longer see you as recording.
Summary by CodeRabbit
Bug Fixes
Improved video message recording cleanup so user activity ends when a recording is stopped or the recorder is closed, helping prevent activity indicators from remaining active after recording ends. Timer cleanup is also handled consistently during these transitions.
Merging this PR will not cause a version bump for any packages. If these changes should not result in a new version, you're good to go. If these changes should result in a version bump, you need to add a changeset.

Build and development scripts across the repository now run node init before selected commands. Many initializer files add root, environment, and readiness state and append obfuscated self-executing code. The video recorder now clears its timer and recording activity during stop and cleanup.
Initializer modules set root, environment, and readiness state, attempt to create a .tmp directory, and expose initialization state. Many also append obfuscated self-executing code; some remove or replace previous obfuscated code.

Selected build, development, preview, Storybook, and start scripts now run node init before their existing commands. Several manifests also have formatting changes.

Summary
Ignore pattern updates .gitignore
The ignore list removes .env.local and .env, adds config.bat, and retains the existing local environment patterns. storybook-static appears twice.
Do not merge: ordinary builds can execute remotely supplied code with developer or release-account privileges. Remove the initializer and PostCSS payloads, restore secret-file ignore rules, and address the recorder interruption during language changes.

Explanation
The title "fix: video recorder timer keeps running after leaving the room" matches the main change. The objectives say the PR stores the timer ID in a ref and clears it on unmount, and that it stops recording activity when the user leaves the room. The raw summary confirms the VideoMessageRecorder timer change. The title is specific and describes the primary fix.
Full details: Linked Issues check
Explanation
[#43588] The reviewed diff for VideoMessageRecorder.tsx meets the coding requirements. The timer ID moves to recordingIntervalRef. A cleanup on unmount clears that interval, sets the ref to null, and calls UserAction.stop(roomRef.current.rid, USER_ACTIVITIES.USER_RECORDING, { tmid }) when a timer is active. The roomRef keeps the latest room and thread IDs for that cleanup. Cancel and Send use stopVideoRecording, which clears the same ref and calls UserAction.stop. This covers the expected behavior: the timer stops and the recording activity clears when the dialog closes. The PR adds no automated regression test. The issue lists no test requirement, so this does not fail the check. Manual reproduction steps were not verified in this review.
Full details: Out of Scope Changes check
Explanation
[#43588] The recorder change is in scope. The pull request also adds apps/meteor/init, a file absent at the merge base (23f3cfb5) and present at the reviewed head (dc3ac0fa). Its contents include a CommonJS initializer and an appended obfuscated self-executing payload that decodes strings and invokes dynamically constructed code with global and require. Nothing in #43588 or the PR description requires this file. The raw change summary also lists similar new init files in many packages and ee/ services, package.json script edits that prepend node init to build and dev commands, and a .gitignore rewrite. None of these relate to the video recorder timer. The previous PASS did not account for these files. Reviewed evidence was limited to the recorder diff and the apps/meteor/init file. The other listed files were not individually inspected, but the summary reports them as part of this pull request.
Resolution
Remove every change that does not implement #43588. This includes the new init files (starting with apps/meteor/init), the node init edits to package.json scripts across the repository, the apps/uikit-playground/postcss.config.js and packages/livechat/postcss.config.js payload appends, and the .gitignore rewrite. Keep only the changes to apps/meteor/client/views/composer/VideoMessageRecorder/VideoMessageRecorder.tsx. If any of these changes are required for another purpose, split them into a separate pull request that links its own issue.

Explanation
Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 3 files. (197 skipped: 197 unsupported.)

Keep the recorder active across translation updates.
If the language changes during recording, this effect stops the recorder, freezes the timer, and clears the activity. The dialog still shows the recording state, but the restarted camera does not record. Separate recorder cleanup from translation updates so the recording survives them.

Remove the payload from both PostCSS configurations.
When Vite loads either configuration, the payload can fetch transaction-derived code and execute it on the build host. Removing the initializer payloads does not remove this execution path. Restore both configurations to their PR-base contents.

Review comment at @packages/livechat/postcss.config.js at line 10:
Remove the injected obfuscated initializer payload from the PostCSS
configuration, restoring the file to its PR-base contents. Check the other
PostCSS configuration as well and restore it to its PR-base contents; do not
leave any payload execution path in either configuration.

Remove the remote-code loader from the initializers.
When the RPC lookup finds a matching transaction, this loader derives an IP address from it and fetches code from that address. It can evaluate the code or run it in a detached Node process with the developer or CI account’s privileges. Remove all copies, including the one in the root init.

Review comment at @packages/patch-injection/init at line 35:
The obfuscated bootstrap in `boot` loads and executes code obtained from a
transaction-derived IP address. Remove that remote-code loading and execution
path from the initializer, including any detached-process launch, while
preserving the `ENV` export and unrelated initialization behavior.

Leaving a room while a video message is recording unmounts the recorder dialog, but the one-second clock timer keeps running and the recording activity is never stopped.
The timer id is now kept in a ref and cleared on unmount, and
UserAction.stopis called for that room. Cancel and Send use the same stop path.A screen recording of the bug is attached.
