Revert spike ports to 3001/5173, add stories 32 and 33

Reverts port changes made during the spike back to default (3001/5173).
Adds two new stories for multi-worktree support: dynamic port management
(story 32) and worktree diff inspection with editor integration (story 33).

+# Story 32: Worktree Agent Orchestration — Dynamic Port Management
+
+## User Story
+**As a** developer running multiple agents in parallel worktrees,
+**I want** each server instance to bind to a unique port automatically,
+**So that** I can run multiple worktree-based agents concurrently without port conflicts.
+
+## Acceptance Criteria
+- [ ] Server discovers an available port instead of hardcoding 3001 (e.g., try 3001, then 3002, etc., or use port 0 and report back).
+- [ ] Server prints the actual bound port on startup so callers can discover it.
+- [ ] Frontend dev server proxy target is configurable (env var or auto-detected from server).
+- [ ] WebSocket client in the frontend reads the port dynamically rather than hardcoding it.
+- [ ] Agent pool can target agents at different worktree server instances by URL.
+- [ ] A simple registry or file-based mechanism lets a supervisor discover which ports map to which worktrees.
+
+## Out of Scope
+- Service mesh or container orchestration.
+- Multi-machine distributed agents (local only for now).

+# Story 33: Worktree Diff Inspection and Editor Integration
+
+## User Story
+**As a** supervisor coordinating agents across worktrees,
+**I want to** view diffs of in-progress agent work and open worktrees in my editor,
+**So that** I can review changes, catch problems early, and intervene when needed.
+
+## Acceptance Criteria
+- [ ] API endpoint (or CLI command) returns `git diff` output for a given worktree path.
+- [ ] API endpoint returns `git diff --stat` summary for a quick overview.
+- [ ] API endpoint can return diff against the base branch (e.g., `git diff main...HEAD`).
+- [ ] A "open in editor" action launches the configured editor (e.g., `zed`) pointed at a worktree directory.
+- [ ] Editor preference is configurable (stored in app settings, defaults to `$EDITOR` or `zed`).
+- [ ] Frontend can trigger "open in editor" for any listed worktree/agent.
+- [ ] Frontend can display a diff view for any worktree with syntax-highlighted changes.
+
+## Out of Scope
+- Full code review workflow (comments, approvals).
+- Automatic merge or conflict resolution.
+- Editor plugin integration (just launching the editor at the worktree path is sufficient).
