funman300 1c396dd562 feat(fifa17): report verified client patch capability
autopatch side of the verified patched-client capability handshake: prove, at
runtime, that the empty-My-Packs resolver guard is active for a specific FIFA
process, and advertise it once on stdout for the launcher to relay.

- Add a per-pid guard verification state derived by a pure, testable
  guard_state_after(cur_before, orig, patch, wrote_ok, cur_after) returning one
  of VERIFIED / UNSUPPORTED_BUILD / WRITE_FAILED / VERIFY_FAILED (NOT_ATTEMPTED
  is the pre-evaluation constant). VERIFIED means the live bytes at RVA 0x14858
  are 7f 0f (JG) after enforcement (from an applied 75 0f->7f 0f, or already
  patched). The existing fail-closed byte guard (guarded_action / STORE_PATCHES_
  GUARDED) is unchanged — this only observes the outcome.
- Emit exactly once per FIFA pid: on VERIFIED,
    [store-guard] verified capability fifa17.empty_mypacks_resolver=1 fifa_pid=<pid>
  otherwise a non-advertising
    [store-guard] guard status=<STATE> fifa_pid=<pid> (no capability advertised)
- Capability constants: EMPTY_MYPACKS_RESOLVER_VERSION=1, fully-qualified name
  "fifa17.empty_mypacks_resolver".
- Tests: 5 guard-state cases + capability-constant assertions (standalone-runnable).

The capability = "the guard was verified in THIS FIFA process", never merely
"the code is present". Design: docs/plans/FIFA17_PATCHED_CLIENT_CAPABILITY.md.

# Store resolver crash-guard for the empty "My Packs" case (bug 6c; PROVEN R1 on the
# tested FIFA 17 build -- see docs/plans/FIFA17_EMPTY_MYPACKS_CLIENT_FIX.md PART IV and
# docs/evidence/FIFA17_EMPTY_MYPACKS_CLIENT_CONTRACT.md).
#
# When no `mypacks` group exists, FIFA's Store resolver receives category id -1. CardsDLL
# FUN_1800147f0 @ 0x180014858 is `JNZ 0x14869` (75 0f): the original treats every non-zero
# category (including -1) as resolvable, calls FUN_180014420, gets NULL, and crashes at the
# [NULL+0x48] deref in FUN_1800147f0 (0x180014882). Changing JNZ->JG (7f 0f) preserves
# positive-category resolution (EDI>0 branch) while routing zero/negative categories through
# the existing Browse/list-all path -> no NULL lookup, no crash, Store opens on Browse Packs.
#
# CAVEAT: this guards the category SIGN only. It does NOT protect a stale *positive* invalid
# ordinal produced by changing the Store group topology (sentinel-present <-> sentinel-absent)
# DURING one running FIFA process -- that reproduced the same crash in the confounded run F3.
# The empty-My-Packs representation MUST stay stable for a FIFA session (see the SESSION-STABLE
# invariant in the client-fix plan).
#
# Orig-verified / fail-closed: applied only when the live bytes are the known original (75 0f);
# already-patched (7f 0f) is a no-op; anything else is logged and SKIPPED (never blindly
# overwritten), so an unrecognised CardsDLL build is not patched.
