BlackMark 3a0d3790ee tsb: pure and tricks tiers reach full oracle feature parity
Both tiers gain the features the asm tier already carries — one-wire
half-duplex (via libavr's new .half_duplex), the config-page activation
timeout, and emergency erase (password \0 + double-confirm wipes flash,
EEPROM and the config page) — on top of the watchdog bail, password gate and
config/flash/EEPROM read-write they already had. pure stays idiomatic
(flash_table info block, one function per command) at 950 B; tricks keeps its
compiler trickery (call-saved global-register page walk, unified runtime-flag
paths pinned noinline/noclone, streaming stores, arithmetic command decode)
at 808 B. Both byte-identical across generated and reflect modes; the size
gradient across the three tiers is now 502 / 808 / 950 B.
