Regenerate WIRE-385 epoch continuation action

[huangminghuang]

Summary

• Generate the typed sysio.epoch::finishadv action with its epoch-index and emission-amount arguments from the canonical SYSIO ABI.
• Add the continuation to the generated contract action interface and action-name registry.

Why

SYSIO publishes operator state after epoch-close mutations through an internal continuation. The SDK declaration must describe that ABI accurately; the declaration grants no new authority, and the contract rejects top-level calls even with epoch-account authorization.

The generated interface adds no recovery policy. WIRE-392 remains required before deployment, with automatic recovery versus controlled halt still undecided.

Validation

• SDK core compilation and hybrid exports passed.
• 14 focused serializer tests passed; the actual Tools-resolved SDK encoded finishadv and three bootstrap actions against the current SYSIO ABIs, and rejected an invalid canonical slug.
• Tools builds against the compiled sibling SDK candidate, allowing integration validation before package approval or publication.
• Coordinated E2E: 15/15 flows passed. Verified remote checkouts: SYSIO 67fe61c2, Ethereum 3f23632a, Libraries 99c5c14a and Tools d50fc784, with unchanged Solana cbf72188 and CDT a00bd718. Tools installed SDK 1.0.93 directly from the candidate Libraries checkout. Post-remit rotation on both outposts and eligible collateral withdrawal passed; optional flow-swap-epoch-stress is excluded.
• The known upstream SDK strict-null error (Builtins.ts:89, TS2722) is waived as a prerequisite for this E2E run only; it remains unresolved.

Companion PRs

• SYSIO #603: produces post-mutation rosters and the canonical continuation ABI; coordinate the consumer update before deploying this producer.
• Ethereum #198: enforces immediate revocation and usable next-group admission; deploy its matching library and inbound implementation together before the SYSIO producer change.
• Tools #97: verifies post-termination rotation and eligible collateral withdrawal against the coordinated contract and SDK candidates.
