Splits the 391-line bootstrapApplication god function into a thin
orchestrator plus 7 focused modules under src/main/bootstrap/:
prepare-logger, prepare-database, prepare-services (service graph +
ipc wiring), wire-api-server (14-callback dictionary), recover-
scheduled-posts, run-startup-health-checks, recover-interrupted-tasks
(crash notification + clean-shutdown task resumption). Original
startup order, before-quit cleanup, and error handling are preserved;
the entry file drops to 153 lines.
