fix: persist channel activation state across restarts

[zmanian]

Summary

• Persist active channel names to settings store under activated_channels key when channels are activated or removed via the web UI
• Auto-activate persisted channels on startup (skipping channels already loaded from disk)
• Fixes Bug: Every time ironclaw is (re) launched the telegram channel is not active #392: channels activated through the web UI are lost on restart

Test plan

• Activate a WASM channel via the web UI, restart IronClaw, verify the channel is auto-activated
• Remove a channel via the web UI, restart, verify it is not auto-activated
• Verify channels loaded from disk at startup are not double-activated

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical usability issue by ensuring that the activation state of WASM channels is preserved across application restarts. It introduces mechanisms to persist active channel names to the settings store and to automatically re-activate these channels when the application starts, significantly improving the user experience for managing extensions.

Highlights

• Channel State Persistence: Implemented functionality to save and load the names of actively used channels to and from the application's settings store.
• Automatic Activation: Configured the application to automatically activate channels that were active in a previous session upon startup.
• Bug Fix: Resolved an issue where channels activated via the web UI would not remain active after an application restart.

Changelog

• src/extensions/manager.rs
  • Added persist_active_channels asynchronous function to save current active channel names to the settings store.
  • Added load_persisted_active_channels asynchronous function to retrieve previously saved active channel names from the settings store.
  • Integrated calls to persist_active_channels when a WASM channel is removed.
  • Integrated calls to persist_active_channels when a WASM channel is hot-activated.
• src/main.rs
  • Created a HashSet to track WASM channels loaded from disk at startup.
  • Implemented logic to load persisted active channels and activate them if they were not already loaded from disk, preventing double-activation.

Code Review

This pull request introduces persistence for activated channels, ensuring they are automatically re-activated on restart. The implementation correctly adds calls to persist the channel state upon activation and removal, and includes logic at startup to load and activate these persisted channels. My review focuses on improving the robustness of the new loading mechanism. I've suggested a change to add logging for potential database or deserialization errors, which will enhance observability and aid in debugging.
