The launcher Hybrid controller mode (built first, for Tomba, to mimic Tomba:
Special Edition) flips the emulated pad's reported type 0x41<->0x73 on
d-pad<->stick. After the real DualShock config state machine was added for MMX6
(98aa688), that flip regressed every game's libpad re-detect into a 1-frame
"pad unplugged": Tomba unpauses its menu / drops input, MMX6 phantom-dashes.
The modern config SM is correct and required by MMX6, so instead of weakening it
globally, restore the pre-98aa688 "config commands always answer 0xF3" behaviour
as a per-game opt-in: [controller] legacy_pad_config (default OFF). Only Tomba
sets it; with the flag off the modern pad path is byte-for-byte unchanged, so no
other title is affected. A/B verified live: legacy = clean Tomba flip / MMX6
input; modern = Tomba disconnect + MMX6 dash.
Explicitly LEGACY: a correct findpad/re-detect refactor would make the flip
benign for every game with no per-game branch (real hardware tolerates unlimited
analog-button presses); when that lands this whole feature set is to be removed.
Full rationale in sio.c (g_pad_legacy_cfg).
Also includes the deferred coherent pad-type apply (pad_type_req, applied only at
an idle/non-config bus boundary so a flip can't split a poll/handshake) and a
`pad_cfg` debug command + tools/padcfg.py + tools/sio_flip_trace.py used to A/B
the config SM live.
