Upgrades the Chia dependencies to their latest releases:

Dependency	Before	After
clvm-traits	0.51.0	0.54.0
clvm-utils	0.51.0	0.54.0
clvmr	0.21.0	0.22.0
chia-wallet-sdk-wasm (playground, npm)	^0.29.0	^0.38.0

Transitively, chia-bls, chia-sha2, chia-traits and chia_streamable_macro move from 0.38.2 to 0.52.1. No source changes were needed; the clvmr 0.21 → 0.22 diff only adds a feature-gated diagnostics module and renames rand imports, so costs and semantics are unchanged (no snapshot changes).

Also:

• After the upgrade nothing depends on getrandom 0.3, so the getrandom_03 wasm shim is removed; the getrandom 0.4 wasm_js entry stays because clvmr and k256/p256 still use it.
• keccak (under clvmr → sha3) moves from the yanked 0.1.5 to 0.1.6.

chia-sha2 still appears at two versions (0.52.1 via clvmr → chia-bls, 0.54.0 via clvm-utils). That split comes from upstream and existed before (0.38.2 / 0.51.0).

Decision to confirm

• chia-wallet-sdk-wasm isn't imported anywhere in playground/src. I bumped it since it's a Chia dependency; removing it from package.json instead is the alternative.

Checked locally

Workspace clippy with -D warnings, clippy and a release build of rue-wasm for wasm32-unknown-unknown, cargo test --all-features --workspace, cargo fmt --check, rue fmt --check, cargo machete, cargo ws publish --dry-run, and the rue-tests snapshots. The pnpm builds of wasm/ and playground/ weren't run (no wasm-pack locally); the lockfile was regenerated with pnpm 10 to match CI.
