Rewrites comprehensive_gui_ux_20260228 spec and plan using deep analysis of
the actual gui_2.py implementation (3078 lines). The previous spec asked to
implement features that already exist (Track Browser, DAG tree, epic planning,
approval dialogs, token table, performance monitor). The new spec:
- Documents 15 already-implemented features with exact line references
- Identifies 8 actual gaps (tier stream panels, DAG editing, cost tracking,
conductor lifecycle forms, track-scoped discussions, approval indicators,
track proposal editing, stream scrollability)
- Rewrites all 5 phases with surgical task descriptions referencing exact
gui_2.py line ranges, function names, and data structures
- Each task specifies the precise imgui API calls to use
- References docs/guide_architecture.md for threading constraints
- References docs/guide_mma.md for Ticket/Track data structures
Also adds architecture documentation fallback references to:
- conductor/workflow.md (new principle #9)
- conductor/product.md (new Architecture Reference section)
