CP-14901: Bump avalanchejs to 5.1.1-alpha.2, core SDKs to alpha.94, vm-modules to 4.0.1 for final ACP-236 wire format

[B0Y3R-AVA]

Description

Ticket: CP-14901 (upstream SDK alignment: CP-14767)

Moves mobile to the final ACP-236 wire format, now that Helicon is live on Fuji — mirroring the extension's core-extension#1000:

• @avalabs/avalanchejs 5.1.0-alpha.5 → 5.1.1-alpha.2 (direct dep + root resolution). 5.1.0-alpha.x ships the draft ACP-236 codec; against a Fuji 1.15.0 node it misreads the new length-prefixed NodeID in AddAutoRenewedValidatorTx and fails with couldn't unmarshal interface: unknown type ID (see Slack thread and core-vm-modules#462). The codec fix is fix: align acp-236 transactions encoding (avalanchejs#1000).
• Core SDKs 3.1.0-canary.672f5c3.0 → 3.1.0-alpha.94. The canary (cut for additionalOutputs on delegator txs) is fully contained in alpha.94 (avalanche-sdks#785), which additionally includes fix: align acp-236 transaction types (avalanche-sdks#792) — i.e. core-wallets-sdk is now compiled against the final codec, closing the "wallets-sdk rebuild" follow-up from the earlier revision of this PR (parseAddAutoRenewedValidatorTx now matches the final format).
• vm-modules 4.0.0 → 4.0.1. The only change between the tags is chore: update sdks (core-vm-modules#463), aligning the modules' own avalanchejs/SDK pins to 5.1.1-alpha.2 / alpha.94.
• yarn.lock confirms a single @avalabs/avalanchejs@5.1.1-alpha.2, single core-wallets-sdk@3.1.0-alpha.94, and single vm-module-types@4.0.1 after the bump — no duplicate copies that could break instanceof checks in signing code.

Screenshots/Videos

N/A — dependency bump, no UI change.

Testing

Dev Testing (if applicable)

• tsc -p . clean (fresh build, no incremental cache).
• Full unit suite passes: 356 suites / 4361 tests.
• Happy path: P-Chain flows (stake, claim, cross-chain C↔P import/export) unchanged — the changed avalanchejs/SDK surfaces are scoped to ACP-236.
• ACP-236 on Fuji: with the final codec now in both avalanchejs and wallets-sdk, AddAutoRenewedValidatorTx should unmarshal and parse end to end — pending re-verification on a Fuji build of this revision.

QA Testing (if applicable)

• Regression-test P-Chain staking and cross-chain (C↔P) flows on both mainnet and Fuji.

Pull request overview

This PR updates the monorepo to use @avalabs/avalanchejs@5.1.1-alpha.2 so Core Mobile picks up the final ACP-236 wire-format encoding/decoding behavior (via both the direct dependency and the root-level Yarn resolution), aligning mobile with Fuji’s Helicon-era node behavior.

Changes:

• Bump @avalabs/avalanchejs from 5.1.0-alpha.5 → 5.1.1-alpha.2 in packages/core-mobile.
• Update the root Yarn resolution for @avalabs/avalanchejs to force the whole workspace dependency tree onto 5.1.1-alpha.2.
• Refresh yarn.lock to reflect the single resolved @avalabs/avalanchejs@5.1.1-alpha.2 entry and updated checksums.
