refactor: support canonical enum aliases

[MuncleUscles]

What changed

• add first-class enum alias support to the shared Rust, Python, Go, and RST generators
• rename nested storage views to LatestFinalized and LatestDecided
• preserve LatestFinal / LatestNonFinal as deprecated source and serde aliases
• update the nested-call storage-mode documentation

Why

LatestNonFinal described an implementation queue rather than the state-view contract. The view actually means the latest state-changing decided transaction, with finalized state as the fallback. Canonical naming makes that contract explicit without changing wire values.

Compatibility

Wire values and calldata encoding are unchanged. Old source names and serialized names remain accepted.

Validation

• Nix genvm-tool package build and unit tests
• focused genvm_modules_interfaces compatibility test
• generated Rust/Python/Go output parity
• full optimized v0.3-dev executor build through the manager umbrella

Summary by CodeRabbit

• Improvements

  • Renamed storage state options to latest_finalized and latest_decided for clearer terminology.
  • Existing names remain supported for compatibility.

• Documentation

  • Updated contract call documentation to reflect the renamed storage state options.

[github-actions]

👋 This PR targeted main, so I've retargeted it to the latest dev branch v0.6-dev.

main is protected and is only an alias of the latest release branch (v0.6-dev), kept in lockstep automatically. Active v0.6 work lands on v0.6-dev, which reaches v0.6.x through the standing release-gate PR once the cross-repo E2E matrix is green.

📝 Walkthrough

Walkthrough

NestedStorageType now uses LatestFinalized and LatestDecided. Legacy Rust names and serialized names remain supported. Regression tests cover compatibility and calldata encoding. The CallContract documentation uses the new storage state values.

Nested storage naming

Layer / File(s)	Summary
Storage state naming compatibility crates/modules-interfaces/src/nested.rs, docs/website/src/spec/02-execution-environment/03-wasi_genlayer_sdk/02_gl_call.rst	NestedStorageType adds LatestFinalized and LatestDecided, with deprecated Rust constants and serialized aliases for the previous names. Tests verify legacy matching, alias deserialization, and equivalent calldata encoding. The CallContract documentation uses the new names.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 4341c

The renamed storage views preserve compatibility, but the documentation should clarify the behavior of latest_decided, including its finalized-state fallback, so callers do not select the wrong view. The PR is mergeable with explicit documentation follow-up.

GenVM PR actions

Tick a box to run it (the box unticks itself when handled). Actions only run while the PR has the ci-safe label.

• Force run full tests
• Rerun full tests
• Provision executor PRs
• Merge into dev

Merge

Requires, on the exact head commit:

• an approving review from a maintainer (any push revokes it), or the rtm label
• linear history — 0 commits behind base
• green full GenVM CI and green cross-repo E2E

Full CI runs only when run-full-tests or rtm is set; "Force run full tests" is a sticky toggle for the former.

Every repo lands ONE squashed commit, subject <PR title> (#N).

Commands

• /genvm-force-merge — repo admin only: land without the review, full-CI and E2E gates, for when those signals are unobtainable, not when they are red. Base, title and 0-behind still apply, and the skip is recorded on the PR.

Define the latest_decided storage-view behavior.

The new label does not state that value 2 selects the latest state-changing decided transaction and falls back to finalized state. Add this behavior near the numeric mapping. This distinction is required for callers to select the correct storage view.
