## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
After the remaining inline runtime logic and composer gaps are extracted, `src/main.ts` should be split along boot-phase boundaries so the entrypoint stops mixing service construction, domain runtime composition, and handler wiring in one file. This task tracks that structural split: move service instantiation, runtime composition, and handler orchestration into dedicated boot modules, then leave `src/main.ts` as a thin lifecycle coordinator with clear startup-path selection.
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Service instantiation lives in a dedicated boot module instead of a large inline setup block in `src/main.ts`.
- [ ] #2 Domain runtime composition lives in a dedicated boot module, separate from lifecycle and handler dispatch.
- [ ] #3 Handler/composer invocation lives in a dedicated boot module, with `src/main.ts` reduced to app lifecycle and startup-path selection.
- [ ] #4 Existing startup behavior remains unchanged across desktop and headless flows.
- [ ] #5 Focused tests cover the split surfaces, and the relevant runtime/typecheck gate passes.
<!-- AC:END -->
## Implementation Plan
<!-- SECTION:PLAN:BEGIN -->
Recommended sequence:
1. Re-scan `src/main.ts` after TASK-238.6 lands and mark the remaining boot-phase seams by responsibility.
2. Extract service instantiation into `src/main/boot/services.ts` or equivalent.
3. Extract runtime composition into `src/main/boot/runtimes.ts` or equivalent.
4. Extract handler/composer orchestration into `src/main/boot/handlers.ts` or equivalent.
5. Shrink `src/main.ts` to startup-path selection, app lifecycle hooks, and minimal boot wiring.
6. Verify the split with focused entrypoint/runtime tests first, then run the broader runtime gate if the refactor crosses startup boundaries.
Guardrails:
- Keep the split behavior-preserving.
- Prefer small boot modules with narrow ownership over a new monolithic bootstrap layer.
- Do not reopen the inline logic work already tracked by TASK-238.6 unless a remaining seam truly belongs here.
