Cracks EDDM-LOWW (coverage 4/10 -> 5/10) and generalises DCT-too-long
(ROUTE165) repair:
- airway_path_avoiding(): the splice now builds the avoid-aware graph, so
re-routing a too-long DCT never re-introduces a RAD-forbidden airway.
- Off-airway absorb: when a broken segment's from-point isn't on any airway
(a SID/terminal fix, e.g. ALUTU), splice from the previous on-airway
point through to the target, dropping the DCT-only detour
(EDDM …BIBAG DCT ALUTU DCT AGNAV -> BIBAG airway AGNAV).
- PROF204 repair now bans the *segment* X<airway>Y (seg_key) instead of
excluding the points, so a forbidden airway leg out of a SID/STAR gateway
(BIBAG) no longer nukes the gateway itself.
Batch: 5/10, no regression. 49 tests green.
