fix(ci): link soul.c only — drop multi-module cc that triggers capability #error

elb generates a dist/soul.c with all El modules inlined. Linking
dist/soul.c alone is sufficient and is exactly what the local mac
build does. Including other dist/*.c files causes two failures:
  1. dist/chat.c has a capability-violation #error that fires when the
     file is compiled as a utility module (outside the cgi entrypoint).
  2. --allow-multiple-definition masked other issues silently.

Drop OTHER_C, drop --allow-multiple-definition, drop the now-unused
elp-c-decls.h generation step. The cc command now matches the proven
local build exactly.

+// The guard is top-level imperative boot code. This file tests the predicate
+// logic as pure functions to verify the conditions exhaustively:

+//   safe_to_seed = !using_http_engram &&
+//                  !(guard_disk_len > 200000 && loaded_nodes * 16000 < guard_disk_len)
+//
+// Scenarios:
+//   - Boundary: 199,999 bytes + sparse -> safe_to_seed == true
+//   - Boundary: 200,001 bytes + sparse -> safe_to_seed == false
+//   - Ratio:    47MB + 63 nodes -> false (the 2026-06-14 clobber scenario)
+//   - HTTP mode -> false unconditionally
+//   - Multiplication form vs old division form near 250KB boundary
