New() returns Result, accepts CoreOption functionals.
Restores v0.3.3 service registration contract:
- WithService(factory func(*Core) Result) — service factory receives Core
- WithOptions(Options) — key-value configuration
- WithServiceLock() — immutable after construction
Services registered in New() form the application conclave with
shared IPC access. Each Core instance has its own bus scope.

- TestEnv_DIR_HOME checks CORE_HOME override first
- Path tests use Env("DS") instead of hardcoded "/"
- Path() falls back to "." when DIR_HOME is empty
- Doc comment no longer claims "zero filepath import"
