jaeone94 45f112e226 fix: node replacement fails after execution and modal sync (#9269)
## Summary

Fixes two bugs in the node replacement flow: placeholder detection
failing after workflow execution or pack reinstallation, and missing UI
sync in the Errors Tab when replacements are applied from the modal
dialog.

## Changes

- **Placeholder detection**: Node placeholder detection now matches
against `targetTypes` (derived from the replaceable node list built at
workflow load time) instead of relying on `has_errors` flag or
`registered_node_types` lookup. This ensures replacement works reliably
after execution (where `has_errors` gets cleared) and after pack
reinstallation (where the type becomes registered).
- **Modal → Errors Tab sync**: Added
`executionErrorStore.removeMissingNodesByType()` call in
`MissingNodesContent.vue` after replacement, so the Errors Tab reflects
changes immediately without requiring a page reload.

## Review Focus

- `collectAllNodes` predicate change in `useNodeReplacement.ts`: now
uses `targetTypes.has(originalType)` to find nodes by their original
serialized type. This is independent of runtime state like `has_errors`
or `registered_node_types`.
- `executionErrorStore.removeMissingNodesByType` call timing in
`MissingNodesContent.vue` — runs synchronously after
`replaceNodesInPlace` resolves, before auto-close logic.

Release Schedule

The project follows a structured release process for each minor version, consisting of three distinct phases:

  1. Development Phase - 2 weeks

    • Active development of new features
    • Code changes merged to the development branch
  2. Feature Freeze - 2 weeks

    • No new features accepted
    • Only bug fixes are cherry-picked to the release branch
    • Testing and stabilization of the codebase
  3. Publication

    • Release is published at the end of the freeze period
    • Version is finalized and made available to all users

Nightly Releases

Nightly releases are published daily at https://github.com/Comfy-Org/ComfyUI_frontend/releases.

To use the latest nightly release, add the following command line argument to your ComfyUI launch script:

--front-end-version Comfy-Org/ComfyUI_frontend@latest

Overlapping Release Cycles

The development of successive minor versions overlaps. For example, while version 1.1 is in feature freeze, development for version 1.2 begins simultaneously. Each feature has approximately 4 weeks from merge to ComfyUI stable release (2 weeks on main, 2 weeks frozen on RC).

Example Release Cycle

Week Date Range Version 1.1 Version 1.2 Version 1.3 Patch Releases
1-2 Mar 1-14 Development - - -
3-4 Mar 15-28 Feature Freeze Development - 1.1.0 through 1.1.13 (daily)
5-6 Mar 29-Apr 11 Released Feature Freeze Development 1.1.14+ (daily)
1.2.0 through 1.2.13 (daily)
7-8 Apr 12-25 - Released Feature Freeze 1.2.14+ (daily)
1.3.0 through 1.3.13 (daily)
