feat: CAP platform requirement + LOAD rejection hint (v3.6.36)

Browse Source 
capmem derives the minimum platform from the CAP's Import component
(javacard.framework -> Java Card level via the SDK-kit corpus, int flag)
and /api/cap-info exposes it; the CAP details show it as a Platform row
('Java Card >= 2.2.2 - CAP format 2.1 - int support').

A failed RAM install at a LOAD / INSTALL [for load] step now appends a
hint naming the import requirement and the smaller-block fallback
(ramInstallFailHint, pure): JC VM spec 4.5.2 makes every import a
'>= version' demand on the card's own packages checked while the load
file is verified - live 2026-09-29, a CAP requiring Java Card 2.2.2 was
rejected exactly at the block containing the end of Import (6438 at
240 B blocks, 6985 at 64 B), not at a step count.
