#2174: store VSCode user-data under $IDE_HOME/.ide/vscode/<workspace>/config

[quando632]

This PR fixes #2174 (part of #2142)

Moves VSCode user-data out of the workspace into the dedicated $IDE_HOME/.ide/vscode/«workspace»/config folder so workspaces stay clean and independent of the IDE.

Stacked on #2175 (#2172 – getIdeMetadataPath()); its commits appear here until #2175 is merged, then this branch is rebased onto main.

Implemented changes:

• Vscode.configureToolArgs now points --user-data-dir to getIdeMetadataPath().resolve("config") instead of «workspace»/.vscode/.userdata. The folder VSCode opens (getWorkspacePath()) is unchanged.
• Migration Mig202608001 (target 2026.08.001) moves any existing .vscode/.userdata of every workspace to the new location. It is idempotent: skips workspaces already migrated and skips (with a warning, no overwrite) if a target already exists. Registered in IdeMigrator.
• Tests: VscodeTest.testConfigureToolArgsUsesIdeMetadataPathForUserData, Mig202608001Test (move, no-op, and target-exists cases).

Testing instructions

1. cd cli && mvn -Dtest=VscodeTest,Mig202608001Test,IdeMigratorTest test — all pass.
2. Manual: create $IDE_HOME/workspaces/main/.vscode/.userdata/state.json, run ide update, verify it moved to $IDE_HOME/.ide/vscode/main/config/state.json and the workspace no longer contains .vscode/.userdata.
