L-33: Standard Components Sharing a Procedure Root Are Misreported as Custom

Account interface inference collects the exported procedure roots of an account into a mutable set and passes that set through a fixed sequence of standard component checks in `from_procedures`. Each check in `extract_component` matches when every root of the candidate component is present in the set, and then unconditionally removes those roots from it. Roots that survive the sequence are reported as `Custom`. Because a match claims its roots permanently, a root exported by two standard components is consumed by whichever component appears first in `extract_standard_components`, and the second component can no longer satisfy the all-roots-present condition.

The fungible faucet component and the code inspection component are a concrete instance, since both re-export `has_procedure` from `code_inspection.masm`, and `add_procedure` stores a root shared across components only once. An account that installs both components is therefore reported as a fungible faucet alone, with the three roots unique to the code inspection component placed in the `Custom` bucket. Reordering the sequence does not resolve the collision, because neither root set is a subset of the other, so checking code inspection first would suppress fungible faucet detection instead. The consequence is an incorrect component list returned by a public off-chain helper, which can mislead tooling and capability checks built on `AccountInterface`. The shipped faucet constructors do not install the code inspection component, so reaching the condition requires a hand-composed account, and the same collision would apply to the non-fungible faucet component once it is added to the standard component enumeration.

Consider matching each standard component against an unmutated copy of the exported root set and deriving the `Custom` bucket only after the full component set has been determined, or tracking each root with a reference count so that a shared root can satisfy more than one standard component.
