Name projectile private owners and data from January evidence

Configuration-only prerequisite; zero credit by itself. Replaces csplit
labels in projectiles.obj with authenticated static names, edited in place:
- _projectile_detonate (e8110) and _projectile_collision (e88c0): January debug
  map atlas, exact tier.
- _projectile_set_action (e7630), _projectile_effect_new (e7650) and
  _projectile_collision_test_line (e7f10): no atlas or PDB record (the
  projectiles PDB module is stripped); identified by January caller graph,
  register ABI and relocations plus the matching HCEA projectile_*.c bodies.
- Data: _rdata_00279068 -> _seconds_per_tick (0x3d088889 = 1/30),
  _data_00306b30 -> _projectile_update_section, and a new _effect_marker_names
  at +0x5F8, following the identical particles.obj precedent
  (_particles_update_section / _particle_effect_marker_names).
None is referenced from another object.
