Remove ALL git dependencies + submodule path-deps from raindex (zero exceptions)

[thedavidmeister]

Tracking issue: get raindex's Rust workspace off all git dependencies and submodule path-deps — no exceptions. End state: every dep resolves from crates.io (Solidity from soldeer), there are zero git = … entries, and the git submodules are deleted.

Direct git deps (root Cargo.toml)

dep	current source	target	status
alloy-ethers-typecast	git rainlanguage/alloy-ethers-typecast	remove entirely (replaced by alloy Provider primitives)	refactor done in working tree (soldeer branch); needs commit + lockfile regen
rain-erc	git rain.erc @rev	crates.io	✅ rain-erc 0.1.1 published — swap ready
rain-error-decoding	git rain.error @rev	crates.io	❌ not published — publish first
wasm-bindgen-utils	git rain.wasm @rev	crates.io	⚠️ only 0.0.12-alpha.20 on crates.io — needs a release / version alignment

Submodule path-deps (lib/rain.interpreter/…)

path-dep	crate	target	status
rain-math-float	rain-math-float	crates.io	✅ 0.1.4
rain-metadata-bindings	rain-metadata-bindings	crates.io	✅ 0.1.1
rain-metaboard-subgraph	rain-metaboard-subgraph	crates.io	🔄 publishing (see rain.metadata#120 push-race)
rain-metadata (cli)	rain-metadata	crates.io	❌ cli still has its own alloy-ethers-typecast git dep → remove it, then publish a clean 0.1.x
rain_interpreter_bindings	rainlang_bindings	crates.io	❌ publish (rainlang autopublish)
rain_interpreter_dispair	rainlang_dispair	crates.io	❌ publish
rain_interpreter_parser	rainlang_parser	crates.io	❌ publish (needs bindings + dispair on crates.io first for version coord)
rain-interpreter-eval	rainlang-eval	crates.io	❌ blocked by foundry-evm (git-only) — must be resolved, see below

The foundry-evm blocker (must be resolved, NOT accepted)

rainlang-eval is a runtime dependency of raindex (crates/common fuzz/replays/add_order, crates/quote quote_debug) and currently depends on foundry-evm, which is git-only and cannot be published to crates.io. This is the hardest blocker, but it is not an accepted exception — to reach zero git deps it must be resolved, e.g.:

• migrate rainlang-eval to a crates.io-published EVM (e.g. revm directly) instead of foundry-evm, or
• vendor / replace the foundry-evm usage with registry-published equivalents.

Interim milestone (optional, to delete the submodule sooner): raindex may temporarily consume rainlang-eval as a rev-pinned git dep pointing at github.com/rainlanguage/rain.interpreter so the submodule can be dropped ahead of the foundry-evm work. This is a stepping stone only — the final state still requires rainlang-eval (and therefore foundry-evm) on crates.io with no git deps remaining.

Solidity submodules → soldeer (raindex#2586)

sushixswap-v2, rain.deploy, rain.raindex.interface, rain.interpreter (contracts) factor out via the soldeer migration, not crates.io.

Sequenced plan

1. Publish rain-error-decoding; release/align wasm-bindgen-utils.
2. Remove alloy-ethers-typecast from the rain-metadata cli, publish rain-metadata 0.1.x.
3. Publish rainlang_bindings, rainlang_dispair, then rainlang_parser.
4. Resolve foundry-evm for rainlang-eval and publish it to crates.io (hardest item — track as needed).
5. Land the typecast removal (already drafted) + Cargo.lock regen.
6. Swap raindex root Cargo.toml: every dep → crates.io versions (Solidity → soldeer).
7. Delete the now-unused submodules.

Done when

• raindex root Cargo.toml has zero git = … deps (including rainlang-eval), no submodule path-deps, and the git submodules are removed.
