funman300 704482be84 tools(re): watch resident club-item population for route correlation
Read-only watcher that waits for FIFA17.exe, re-resolves the club-item store
each tick (the manager is reallocated per login), and emits one timestamped line
per CHANGE. Pair it with

    journalctl -u openfut-staging-host -o short-iso

to answer "after which response does a resident club item first appear?" by wall
clock, without having to reverse the constructor first.

Re-resolving per tick matters: the store is reached through
[CardsDLL+0x2e6398] -> vtable[0x4e8], and that getter is a `lea`, so the manager
is an embedded subobject whose address moves with the owner. The tool also
re-checks the module base against a known immediate every time it attaches and
refuses to report from a wrong base.

Verified against the currently live client: club=0/5 players=18/23.

Staging can host the session: every bootstrap route probed answers 200
(userMassInfo, squad/active, squad/list, club/stats/*, hub, user, club arms,
item idList, clubUser, season/list, watchList, purchased/items, settings,
clientdata) with the single exception of /statistics/tournament, which 502s
because staging's Python upstream is deliberately dead and which is not on the
club bootstrap path.

funman300 0997dd3b60 tools(re): census FIFA 17's resident club-item vector
Read-only /proc/PID/mem census of the client's resident club-item store, which
is what the pre-match kit selector actually consumes. No writes.

Resolves the whole chain from static RE rather than guessing offsets:

  [CardsDLL+0x2e6398]        -> owner object       (FUN_18011a830 is a plain
                                                    global read)
  owner->vtable[0x4e8]       -> lea rax,[rcx+0x1f9d8]; ret, i.e. mgr is an
                                EMBEDDED subobject, not a pointer
  mgr+0x108 .. mgr+0x110     -> club-item vector, stride 24
  element+0x10               -> the item record    (FUN_1800d73d0)

CardsDLL is located by its NEAREST PRECEDING NAMED mapping, because Wine maps PE
sections anonymously and the Wine heap is also rwx, so permissions do not
discriminate code from heap. The base is then sanity-checked against a known
immediate (mov edx,0x7575 at 0x180026fea) and the tool aborts rather than
reporting from a wrong base.

Field offsets are the ones already proven, and nothing else is interpreted:
+0x4c cardtype, +0x50 cardsubtypeid, +0x5c itemState, +0x60 category,
+0x94 teamid, +0xba teamkittypetechid (u16).

FIRST RESULT, live on the client parked at the pre-match kit selector:

  players    mgr+0x0d8: 23 slots, 18 non-null, all (cardtype 1, subtype 0)
  club items mgr+0x108:  5 slots,  0 non-null

Five slots, every item pointer NULL. Five is the club's active club-item set --
home kit, away kit, badge, stadium, ball -- so the client knows it should hold
five and holds none. That is why FUN_1800d73d0 returns the 0x1802c2a28 sentinel
whose +0x10 is NULL, and why the tiles are untextured.
