* fix(state_machine): reject public transactions that silently drop a declared account
ValidatedStateDiff::from_public_transaction never checked that the accounts
touched in a program's output matched the caller-declared message.account_ids
— it just folded whatever pairs the program returned into the diff. A program
(or a macro-generated dispatcher wrapping one) that silently drops an account
from both sides of its own output together stays internally consistent
(pre_states.len() == post_states.len()) and passes validate_execution's
existing checks, so the dropped account simply vanishes with no error.
Add a check after the chained-call loop: every account_id in
message.account_ids must appear in the final state_diff, or the transaction is
rejected with the new DeclaredAccountMissingFromOutput error.
Add a dropped_account test-guest program that reproduces the exact shape of
the bug (two pre_states in, one consistent (pre, post) pair out) and a
regression test proving the transaction is now rejected. Verified the test
fails with Ok(()) when the check is removed, and passes once it's restored.
* style: tighten comments and apply nightly rustfmt
Condense the explanatory comments on the new account-accounting check and the
dropped_account test guest, and fix imprecise wording (the account is dropped
from both pre_state and post_states together, not just pre_state). Also
applies cargo +nightly fmt's wrapping of the new error message.
* chore: regenerate test fixture after rebase onto dev
* refactor(lee): split large modules into directories and extract tests
Split state.rs, program.rs, circuit.rs, validated_state_diff.rs,
merkle_tree, and core/program.rs into module directories with separate
test files. State tests are further split into themed files (genesis,
authenticated_transfer, circuit, claiming, etc.). Extract
authenticate_public_transaction_signers helper in validated_state_diff
to remove duplicated authentication logic.
* chore: rebuild artifacts
