Fused rounds fire out of arc; safe fuse; proximity misses type as Burst

Operator ruling 2026-09-30: a fused weapon with a selected but out-of-arc
target fires. Its round flies along the arc-clamped aim and bursts at the
target's range. Non-fused weapons still refuse.

- FireControl.ArcPermitsFire is the one trigger arc gate (fused weapons are
  exempt); Fire reads the same InArc through PFire's new designated/inArc
  outs, which replace `bears`. No valid targeting data still bursts at Range.
- F3: a fused weapon whose effective Range does not exceed its BlastRadius
  stays safed at the trigger (FuseCanArm, read from the runtime Range). The
  catalog check on Range.Min is deleted; it read the authored floor, which
  Evaluate can scale below.
- F4: a targeted proximity burst is pulled back along its line to Range.
- F8: a proximity round that detonates commits as Burst (or Hit); Apply's
  Proximity case collapses into the Burst path via Outcome.BurstPoint.
- Tests: arc-only and LockWeapon gates, out-of-arc burst, trigger gate,
  runtime-Range refusal, Range clamp, Burst typing, commit horizon, and
  Soul's adopted probes (aim clamp edges, contact point, target leaves,
  shooter destroyed).
