* fix: enable `miden-crypto/std` in `testing` feature to fix MSRV check (#2544)

The migration to miden-crypto 0.22 replaced `winter_rand_utils::rand_value`
with `miden_crypto::rand::test_utils::rand_value`, which is gated behind
`#[cfg(any(test, feature = "std"))]`. Since the workspace dependency uses
`default-features = false`, crates depending on `miden-protocol/testing`
without `std` failed to compile, breaking the release-dry-run MSRV check.

* feat: migrate miden-agglayer to VM 0.21 and crypto 0.22 (#2546)

* feat: migrate miden-agglayer to VM 0.21 and crypto 0.22

Re-enable the miden-agglayer crate in the workspace and apply all
necessary API and convention changes from the VM 0.21 migration:

Rust changes:
- Remove FieldElement trait imports (removed from miden-core)
- Felt::as_int() -> Felt::as_canonical_u64()
- Program import moved to miden_core::program::Program
- bytes_to_packed_u32_felts -> bytes_to_packed_u32_elements (miden_core::utils)
- AccountId::try_from([Felt;2]) -> AccountId::try_from_elements(suffix, prefix)
- Serializable/Deserializable from miden_assembly::serde (was ::utils)

MASM changes:
- rpo256 -> poseidon2 (hash function migration)
- asset::mem_store/mem_load -> asset::store/load (procedure renames)
- u64::overflowing_mul -> u64::widening_mul
- u128_sub_no_underflow rewritten for LE convention (u64 procedures
  now use [lo, hi] input/output order)
- verify_u128_to_native_amount_conversion updated for LE result order

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: migrate agglayer tests and fix LE convention issues

Re-enable agglayer tests in miden-testing and fix all compilation
and runtime errors from the VM 0.21 migration:

Test compilation fixes:
- FieldElement import removal, as_int -> as_canonical_u64
- AuthScheme::Falcon512Rpo -> Falcon512Poseidon2
- AdviceInputs path: miden_processor::advice::AdviceInputs
- FastProcessor::new_debug -> new().with_advice().with_debugging()
- StackInputs::new(vec![]) -> new(&[])
- bytes_to_packed_u32_felts -> bytes_to_packed_u32_elements
- AccountId::try_from -> try_from_elements

MASM runtime fixes:
- eth_address.masm: fix u32split LE output order in build_felt
  verification (movup.4 -> movup.3 for lo/hi comparison)
- bridge_out.masm: fix create_burn_note note_idx corruption -
  loc_loadw_be overwrites top 4 stack elements including both
  copies from dup; save note_idx to local instead (pre-existing
  bug that only manifested with multiple output notes)
- bridge_out.masm: fix num_leaves storage LE ordering - push
  new_leaf_count to stack top for Word[0] storage, use
  mem_storew_le instead of mem_storew_be for loading
- bridge_config.masm: update GER hash from Rpo256 to Poseidon2
- canonical_zeros: remove .rev() from build.rs generation, swap
  push order for LE memory layout
- Word element ordering fixes for bridge admin, GER manager,
  faucet registry keys, and conversion metadata

Test expectation fixes:
- Rpo256 -> Poseidon2 for GER hash computation
- Removed word reversal in root/proof reading (LE convention)
- Fixed expected storage value ordering
- mem_storew_be -> mem_storew_le in test MASM code

All 39 agglayer tests pass.

* refactor: address PR review comments

- Extract `create_id_key(id: AccountId) -> Word` helper and reuse for
  bridge_admin, ger_manager, bridge_account_id, and faucet_registry_key
- Replace `felts_to_bytes` with re-export of `packed_u32_elements_to_bytes`
  from miden-core (identical implementation)
- Remove stale comment in config_note.rs
- Use `Felt::ONE` instead of `Felt::new(1)` in config_bridge test
- Add TODO comments referencing issue #2548 for getter helpers
- Simplify note_idx handling: use `padw` before `loc_loadw_le` instead of
  saving to a local variable; revert @Locals(15) to @Locals(14)
- Switch `loc_storew_be`/`loc_loadw_be` to `_le` variants in create_burn_note
- Add stack state comments before third overflowing_sub in u128_sub_no_underflow

* chore: padding is 15

* remove utils re-export, faucet_registry_key

* chore: drop 4 words

* fix: pad before call invoc.; explicit stack comments

* fix: unnecesary dup and incorrect movup

* style: codify multi-element naming convention for MASM stack comments

Add convention to masm_doc_comment_fmt.md:
- `value` = single felt
- `value(N)` = N felts (non-word)
- `VALUE` = word (4 felts, no (4) suffix needed)

Apply throughout agglayer MASM: drop redundant (4) from ASSET_KEY,
ASSET_VALUE, SERIAL_NUM, SCRIPT_ROOT, RECIPIENT, NOTE_ATTACHMENT,
PROC_MAST_ROOT, OLD_VALUE, VALUE, U256_LO, U256_HI.

* chore: revert changes to faucet config slot

* chore: revert prefix<>suffix storage ordering

* fix: store flag values at word[0] for LE convention

Change GER_KNOWN_FLAG and IS_FAUCET_REGISTERED_FLAG to be stored at
word[0] instead of word[3]. Under LE, `push.0.0.0.FLAG` puts FLAG at
stack top = word[0], matching the documented layout [1, 0, 0, 0].

Previously `push.FLAG.0.0.0` placed FLAG at stack bottom = word[3],
resulting in Word([0, 0, 0, 1]) which contradicted the docs.

* refactor: explicit pointers for storing prefix/suffix

* refactor: swap to_account_id output to LE convention [suffix, prefix]

All other bridge/faucet MASM procedures use [suffix, prefix] (suffix on
top) for account IDs on the stack. Align to_account_id with this
convention by adding a swap at the end, and update all callers:
- faucet/mod.masm: update get_destination_account_id_data, claim, and
  build_p2id_output_note to handle the new stack order
- solidity_miden_address_conversion test: swap stack index expectations

The constants FAUCET_ID_SUFFIX and FAUCET_ID_PREFIX were swapped
relative to the actual storage layout in config_note.rs (suffix at
index 5, prefix at index 6). This caused register_faucet to store
with a mismatched key, so lookups returned empty.

Also fix the misleading doc comment in config_note.rs.

* fix: use Ownable2Step and OwnerControlled components for agglayer faucet

The NetworkFungibleFaucet's mint_and_send now requires Ownable2Step
for ownership verification and OwnerControlled for mint policy
management. Migrate the agglayer faucet from a custom owner_config
storage slot to these standard components:

- Remove bridge_account_id from AggLayerFaucet (ownership is now
  handled by the Ownable2Step component)
- Add Ownable2Step and OwnerControlled as companion components in
  the faucet account builder
- Use Ownable2Step::try_from_storage to extract the owner in
  bridge_account_id() helper

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: include Ownable2Step and OwnerControlled in faucet code commitment

The build.rs computes the faucet code commitment for validation checks.
After adding Ownable2Step and OwnerControlled as companion components,
the code commitment must include their procedures.

* fix: use mem_storew_le for MINT note storage in bridge_in

The MINT note script reads storage with mem_loadw_le (LE convention),
so the bridge must store the P2ID script root, serial number, and
attachment data using mem_storew_le to match. Using mem_storew_be
caused the P2ID script root hash to be stored with reversed elements,
making it unresolvable by the kernel.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: bridge_in endianness + clippy warnings

- Use mem_storew_le for MINT note storage in bridge_in.masm to match
  the MINT note script's mem_loadw_le reads (VM 0.21 byte-endianness).
- Add MintNote::script() to bridge_in TX3 context.
- Fix clippy useless_conversion warnings in bridge.rs.
- Formatting fix in faucet.rs.
