- Added new README.md for the v3 Event Leads module at `src/routes/events/[event_id]/(leads)/README.md`, adapting content from its legacy counterpart.
- Created placeholder README.md files for the main v3 Events module (`src/routes/events/[event_id]/README.md`), the v3 Launcher module (`src/routes/events/[event_id]/(launcher)/README.md`), and the v3 Badges module (`src/routes/events/[event_id]/(badges)/README.md`).
- Moved legacy event modules (`events_badges`, `events_leads`) to `src/routes/legacy/` and renamed them to `events_badges_v2` and `events_leads_v2` respectively.
- Created new directory structures for Svelte 5 and SvelteKit-based event modules under `src/routes/events/[event_id]/`:
- `(launcher)`
- `(badges)`
- `(leads)`
- Updated `src/routes/events_leads/README.md` (now `src/routes/legacy/events_leads_v2/README.md`) with comprehensive documentation for the legacy lead retrieval module, reflecting its features, data model, routing, components, and technical implementation details, incorporating project conventions.
