Add fuzz inputs #288

Add a few new inputs that cover seven highly critical functions :)

I ran this command across all the corpora:

FUZZ=target_name ./fuzzbuild/bin/fuzz -set_cover_merge=1 -shuffle=0 -prefer_small=1 -use_value_profile=0 ~/qa-assets/fuzz_corpora/target_name ~/bitcoin-core-corpora/target_name

Just realized I could've used the test runner script. But it looks to be pretty much the same merge command.

main: https://marcofleon.github.io/coverage/coverage-2026-08-25/

this pull: https://marcofleon.github.io/coverage/new_inputs_coverage/

lgtm. Size is 100M

I guess CI will fail anyway, so should be fine to merge
