vscode parity: add authorization tree visibility in debug sessions

[Timi16]

Problem

VS Code extension lacks parity for auth-tree display (--show-auth), requiring users to switch to CLI for authorization debugging.

Evidence:

• Matrix/README list as unsupported in extension: docs/feature-matrix.md:59-60, extensions/vscode/README.md:239

Files to change

• extensions/vscode/package.json
• extensions/vscode/src/dap/adapter.ts
• extensions/vscode/src/cli/debuggerProcess.ts
• extensions/vscode/README.md
• docs/feature-matrix.md

Acceptance criteria

• Add optional auth-tree retrieval/display during paused sessions.
• No regression in existing variables/call stack behavior.
• Documentation includes when/where auth tree appears.
