WIP testing performance

[Mbeaulne]

Description

This pull request introduces a Zustand-based state management system for component specifications to improve performance and enable granular updates. The implementation adds a new store that decomposes ComponentSpec objects into normalized graph levels, allowing individual task properties (arguments, annotations, execution options) to be updated without triggering re-renders of unrelated components.

Key changes include:

• Added Zustand dependency (^5.0.11) for state management
• Created componentSpecStore with decompose/compile logic for ComponentSpec normalization
• Implemented granular selectors that only re-render when specific data changes
• Added bridge layer to sync between existing ComponentSpecProvider and new store
• Updated TaskNodeProvider to read from store for stable per-task references
• Modified FlowCanvas to use structural fingerprints for optimized React Flow node recreation
• Enhanced argument and annotation editors to use direct store mutations

Type of Change

• New feature
• Improvement
• Cleanup/Refactor

Checklist

• I have tested this does not break current pipelines / runs functionality
• I have tested the changes on staging

Test Instructions

1. Load a pipeline with multiple tasks and nested subgraphs
2. Edit task arguments and verify only the edited task re-renders
3. Navigate between subgraphs and confirm performance improvements
4. Test bulk operations like node duplication and replacement
5. Verify display name editing works without full component re-renders
6. Confirm React Flow canvas only recreates nodes when structure changes (add/remove tasks, position changes)

Additional Comments

This is Phase 2 of the Component Spec Optimization Milestone (CSOM). The implementation maintains backward compatibility through a bridge layer while introducing performance optimizations. The store uses referential stability to ensure unchanged tasks maintain the same object references, preventing unnecessary re-renders in React components.
