feat(tx-manifest): resolve references and classes

[lukachi]

Stack

PR 4 of 9 in the tx-manifest merge train.

• Base: feature/tx-manifest-engine (PR feat(tx-manifest): add smplx transaction engine #12)
• Next slices build on this branch.
• The final PR absorbs the complete release behavior.

What this adds

• Normalizes free actions and both generations of class/method declarations.
• Resolves request parameters, arguments, deployment fields, bare references, and the deprecated compile_params. namespace by reference site.
• Encodes supported SimplicityHL compile parameters from declared types, including asset-id byte order and fixed-width covenant hashes.
• Reads deployed class instances and derives instances created by constructors.
• Computes dependent covenant hashes to a bounded fixed point and refuses non-converging or malformed compiler results.
• Follows the manifest's declared debug-symbol build mode for ordinary covenant derivation and computed hashes.
• Integrates real smplx covenant compilation and parameter-type discovery while releasing WASM handles deterministically.
• Carries the complete immutable covenant derivation through review: source, arguments, leaves, build mode, address, and scriptPubKey.

Review boundaries

This slice deliberately does not add:

• multi-asset funding, issuance, confidential inputs or outputs, or blinding;
• semantic input/output guards and validation actions;
• developer tooling and corpus-wide inspection;
• confirmation rendering or clear signing;
• credentials, signing, activation, broadcast, or release wiring.

Those remain in later stacked PRs.

Verification

Verified from commit b994c0f in a clean detached worktree with the committed submodules:

• smplx 8f0215c, SDK package 0.0.10
• bun run typecheck:packages
• focused strict TypeScript check for the smplx adapter
• bun run lint (exit 0; existing repository warnings only)
• bun run format:check
• bun test packages/tx-manifest apps/extension/src/core/chains/liquid/adapters/smplx
• 224 tests passed, 0 failed

The repository-wide TypeScript gate has a pre-existing clean-install React/Zod duplicate-type baseline. This stack uses the focused tx-manifest/smplx gate until the cumulative activation/release slice restores and proves the full root check.
