Integrate with the mods actually installed beside us

New integrations.lua, loaded pcall-wrapped at the end of main.lua;
every integration gates on its target's global so a missing mod is
silence. Both targets load before us by priority.

JokerDisplay: each known joker's display definition gains a live
'(2 combos)' counter in JD's own parenthetical reminder style --
the same partner count the hover tooltip names -- by appending a
dynamic element to reminder_text (created when absent) and wrapping
calc_function to fill card.joker_display_values. The wrapper pcalls
the original calc and blanks the text when the new jd_combos config
toggle is off, so it flips mid-run in both directions.

Too Many Jokers: registers the SEARCH_FIELD_FUNCS hook its api.md
documents, indexing every joker under its tag labels on both sides,
so the collection search finds jokers by 'money', 'Hearts',
'held-card retriggers'. Unknown centers stay nil.

The smoke scenario now asserts the JokerDisplay patch against the
real mod: 13/13 in-game.
