fix: resolve runtime metadata and migration directory lookup

Export shared runtime platform and architecture helpers so provider
registry header generation uses the same process-based detection logic
as header profiles instead of direct os module calls.

Improve migration directory resolution by searching upward through
common project layouts and checking multiple candidate paths before
falling back to OMNIROUTE_MIGRATIONS_DIR errors.
