Introduce Settings Icon into Env Manager View

[eleanorjboyd]

fixes #1176

[Copilot]

Pull request overview

This PR introduces a settings icon to the Environment Manager view that opens workspace-level search settings, and changes the default workspace search path from an empty array to ["./**/.venv"] to enable automatic discovery of .venv folders in workspaces.

Changes:

• Adds a gear icon button to the env-managers view that opens search path configuration
• Sets default workspace search path to ./**/.venv for automatic venv discovery
• Updates getWorkspaceSearchPaths() to use default values from package.json when no workspace-specific config exists
• Simplifies test assertions and switches from hardcoded paths to more flexible path validation
• Changes defaultEnvManager scope from "window" to "application" and removes extension version logging

• The comment was updated from "prefer workspaceFolder > workspace" to "prefer workspaceFolder > workspace > default". While this accurately reflects the new code behavior, it's worth noting that this is a significant behavior change. Previously, when no workspace or workspace folder values were set, the function would return an empty array. Now it will return the default value from package.json.

This change means environments will now be discovered in ./**/.venv by default (once the glob pattern issue is fixed), which could significantly impact performance and behavior for users who haven't explicitly configured this setting. Consider whether this breaking change should be communicated to users through release notes or migration guidance.
