fix(openapi): export EvmTx and MultiChainMsg so SkipGoMessage $refs resolve

[trevormil]

Summary

Narrows PR #171 after the 8-route payload-deletion portion was rolled back. The zero-prop payload blocks in routes.yaml are harmless in practice — spread_explodes.ts drops them before the hosted spec ships, so 3p API consumers never see them. Keeping them in routes.yaml as dead weight is preferable to risking an accidental drop of a route param someone actually wanted.

What stays in this PR

Add export to EvmTx and MultiChainMsg in src/gamm/indexer.ts. Both types are referenced transitively by SkipGoMessage but were defined without export, so typeconv skipped them and the hosted spec shipped broken #/components/schemas/EvmTx / MultiChainMsg refs. One-word-each fix. Implements #0292 (partial — the 5 dynamic-store + swap-activities types deferred until PR #168 merges).

What was rolled back

The 8 zero-prop payload param deletions from routes.yaml (ticket #0293). Audit confirmed:

Route	Verdict	Action
GET /developerApp/{clientId}	genuinely-empty	kept as-is
GET /plugin/{pluginId}	genuinely-empty	kept as-is
GET /utilityPage/{utilityPageId}	genuinely-empty	kept as-is
GET /application/{applicationId}	genuinely-empty	kept as-is
GET /claims/status/{claimAttemptId}	genuinely-empty	kept as-is
GET /maps/{mapId}	genuinely-empty	kept as-is
GET /claims/gatedContent/{claimId}	genuinely-empty	kept as-is
GET /plugins/creator	real-props — iGetCreatorPluginsPayload has creatorAddress, bookmark, returnSensitiveData; spread_explodes.ts expands into per-field query params	kept as-is — prior deletion would have stripped these from hosted spec

Seven routes are genuinely empty (handler reads only req.params.{id}); one had real props the first pass missed, reinforcing the call to leave routes.yaml alone.

Test plan

• Typecheck (SDK build) clean
• No unresolved $refs in the hosted spec after the pipeline regenerates (CI will verify)

Greptile Summary

This PR is a focused OpenAPI hygiene pass: it removes 8 dead payload query-parameter blocks from routes.yaml (zero-property schemas that spread_explodes.ts was already silently dropping, so the hosted spec was already parameterless) and exports EvmTx and MultiChainMsg in indexer.ts so typeconv declares them as named component schemas, fixing broken $refs under SkipGoMessage → iEstimateSwapSuccessResponse.

Key points:

• routes.yaml: All 8 removed blocks reference schemas with zero properties, so the pipeline output is unchanged — the source file now matches what was already rendered. The PR description correctly flags iGetClaimAttemptStatusPayload and iGetCreatorPluginsPayload as candidates for a future human sanity-check, which is appropriate.
• indexer.ts: Adding export to EvmTx and MultiChainMsg is the minimal correct fix for the broken schema references. Note that SkipGoMessage (which holds both) remains unexported — it appears typeconv handles it transitively via the exported iEstimateSwapSuccessResponse, which seems to be working in practice already.
• One minor asymmetry removed: the iGetMapPayload block had required: true whereas all other payload blocks were required: false; this inconsistency in the original source is gone with the cleanup.

Confidence Score: 5/5

Safe to merge — both changes are net-neutral on hosted output and fix real spec defects.

The routes.yaml deletions are provably no-ops on the hosted spec (pipeline already drops zero-prop params), and the export additions in indexer.ts are a one-word fix with no runtime impact — TypeScript interfaces are compile-time only. No logic changes, no data-path changes, no security surface added.

No files require special attention; the two flagged routes are noted in the PR description as follow-up items, not blockers.

Important Files Changed

Filename	Overview
packages/bitbadgesjs-sdk/openapitypes-helpers/routes.yaml	Removes 8 zero-property payload query param blocks from GET routes; the spread_explodes.ts pipeline already dropped them, so the hosted spec was already parameterless — this is pure dead-weight cleanup.
packages/bitbadgesjs-sdk/src/gamm/indexer.ts	Adds export to MultiChainMsg and EvmTx interfaces so typeconv declares them as named component schemas, fixing broken $refs in the hosted OpenAPI spec.
