The extension details page still shows the default placeholder icon even
though the repo already carries a root logo asset. This commit captures a
delta-only execution plan that starts with packaging the brand asset into
the installable extension payload and only touches runtime behavior after
audit proves a requested gap still exists.

Constraint: VS Code extension icons must resolve from inside the installed extension directory
Constraint: Active Agents already ships grouped state, repo changes, lock warnings, and AGENT.lock fallback
Rejected: Rewrite the extension runtime from scratch | would duplicate already-landed behavior and widen risk
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Audit the shipped Active Agents behavior before editing provider/session logic; do not reference repo-root logo.png directly from package.json

Not-tested: node --test test/vscode-active-agents-session-state.test.js; manual VS Code icon rendering
