fix: agent manager session disappears due to gitUrl race condition

Fix: Agent Manager sessions disappearing immediately after starting

Fixes an issue where Agent Manager sessions would disappear immediately after starting, particularly when there's already a session running in the right sidebar.

Root Cause

A race condition in currentGitUrl initialization caused Agent Manager sessions to be filtered out immediately after creation:

1. In AgentManagerProvider constructor, initializeCurrentGitUrl() is called asynchronously but not awaited
2. currentGitUrl starts as undefined
3. When startAgentSession() is called, it fetches gitUrl from the workspace and creates the session with this gitUrl
4. postStateToWebview() is called, which uses getFilteredState() with this.currentGitUrl
5. If currentGitUrl is still undefined (because initializeCurrentGitUrl() hasn't completed), but the session has a gitUrl, the session is filtered out by getSessionsForGitUrl()
6. The webview receives state without the session and removes it

Fix

Modified startAgentSession() to update currentGitUrl when fetching the git URL for a new session, ensuring the filter matches the session's gitUrl:

if (gitUrl && !this.currentGitUrl) {
    this.currentGitUrl = gitUrl
    this.outputChannel.appendLine(`[AgentManager] Updated current git URL: ${gitUrl}`)
}

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Overview

This PR correctly fixes a race condition where Agent Manager sessions would disappear immediately after starting. The issue occurs when initializeCurrentGitUrl() (called asynchronously in the constructor) hasn't completed by the time startAgentSession() is called.

The Fix:

• Updates currentGitUrl during session start if it's not already set (lines 476-481)
• Ensures consistency between the session's gitUrl and the filter used to display sessions
• Properly guards against overwriting an already-set currentGitUrl

Code Quality:

• ✅ Logic is sound and addresses the race condition correctly
• ✅ Tests cover both scenarios (updating when not set, not overwriting when set)
• ✅ Follows existing code patterns and conventions
• ✅ Includes appropriate logging for debugging
• ✅ Changeset is properly formatted
