Eliminate duplicate VFS listener registrations in MiseTaskResolver and MiseConfigFileResolver

[Copilot]

Both MiseTaskResolver and MiseConfigFileResolver were calling MiseTomlFileVfsListener.startListening() in their init blocks, creating multiple VFS and PSI tree change listener instances per project.

Changes

• Created MiseTomlFileListener service - Project-level service that owns VFS listener registration, ensuring single initialization
• Refactored resolver init blocks - Both resolvers now subscribe to MISE_TOML_CHANGED topic without registering listeners
• Moved MISE_TOML_CHANGED topic - Relocated from MiseTomlFileVfsListener to MiseTomlFileListener for clearer ownership
• Removed dead code - Deleted unused MiseLocalIndexUpdater instantiation in startListening()

Before/After

Before:

init {
    project.messageBus.connect(this).let {
        it.subscribe(MiseTomlFileVfsListener.MISE_TOML_CHANGED) { cache.clear() }
        MiseTomlFileVfsListener.startListening(project, this, it) // Duplicate registration
    }
}

After:

init {
    project.service<MiseTomlFileListener>() // Ensure listener initialized once
    project.messageBus.connect(this).subscribe(MiseTomlFileListener.MISE_TOML_CHANGED) {
        cache.clear()
    }
}

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cache-redirector.jetbrains.com

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
