⏩Neo Angband: Upstream Catchup v0.1.2

Added

• Post-4.2.6 projection corrections (catchup.projections, off by default). A blast radius larger than the game’s maximum projection range is now held at that maximum, matching upstream commit f0f6bd223 (2026-07-28), which closed upstream issue #6671. Without it a blast reaches distances its own damage table has no entry for, and every grid out there is dealt a damage that is not a number at all. A radius already within range is left exactly as it was, so switching the rule on changes nothing any 4.2.6 spell, breath, wand or trap can ask for - only another mod, or the debug command, reaches the case this covers. This is the mod’s first rule that changes engine behaviour rather than content, and it needs the engine release that added the projection-radius seam; on an older engine the rule is inert and the rest of the mod is unaffected.
