Bump rain-lib-memkv 0.1.5 -> 0.2.0

[thedavidmeister]

What

Moves the rain-lib-memkv pin from 0.1.5 to 0.2.0. foundry.toml and
soldeer.lock come from forge soldeer update. The versioned prefix
rain-lib-memkv-0.1.5/ becomes rain-lib-memkv-0.2.0/ in remappings.txt and
in the five files that import the store:

• src/abstract/RainDeployVerifySnapshotBase.sol
• test/script/Build.t.sol
• test/script/Deploy.t.sol
• test/src/lib/GeneratedSnapshotShape.t.sol
• test/src/lib/LibRainDeploySnapshot.t.sol

soldeer update adds the 0.2.0 remapping but leaves the 0.1.5 line in place.
That line is removed here because nothing resolves through it any more.

Closes #238

Why 0.2.0's aliasing change does not reach this repo

In 0.2.0 a MemoryKV is a handle to memory. Once a store is non-empty, every
copy of its handle refers to the same store, so a write through one copy shows
up in all of them. This repo uses the store only as a string set, and every
site follows one pattern: a fresh MemoryKV x = MemoryKV.wrap(0), then
x = x.set(key, MemoryKVVal.wrap(0)) in a loop, then x.has(key) reads.
Across the five files there are 15 handles and 15 set calls. Each set
assigns back to the handle it was called on. No handle is assigned from
another handle, passed to a function, returned, or saved and restored. No two
copies of a handle ever exist, so there is nothing that could alias. set and
has keep their signatures, and the build compiles unchanged.

QA

• Discriminating tests: n/a. This is a dependency bump. No logic changes here
  and no assertion changes. The set sites above already exercise set and
  has in the existing suite, and CI runs that suite.
• Mutation: stale prefix. With the pin, lock and remapping at 0.2.0 but the
  five imports still on rain-lib-memkv-0.1.5/, forge build fails on every
  one with Error (6275): Source "rain-lib-memkv-0.1.5/src/lib/LibMemoryKV.sol" not found. With the rewrite it compiles (126 files, Solc 0.8.25,
  "Compiler run successful!").
• Oracle: the Soldeer registry
  (api.soldeer.xyz/api/v1/revision?project_name=rain-lib-memkv). 0.2.0 is the
  newest revision (published 2026-09-18T21:06:03Z) at
  0_2_0_18-09-2026_21:06:03_rain.lib.zip, and that is the URL
  soldeer.lock now records.
• Category check: git grep '0\.1\.5' finds no memkv reference. Two hits
  remain, and neither is this dependency. audit/mutation-test-scans.json has
  publishedTag: sol-v0.1.5, which is this repo's own release tag.
  tools/hyperliquid-big-blocks/Cargo.lock has http-body-util 0.1.5, a Rust
  crate.

Explanation

Issue #238 requires the dependency pin, soldeer.lock entry, remapping, and all versioned Solidity import prefixes. The summary shows the pin changed in foundry.toml, the remapping changed, and five Solidity imports changed to 0.2.0. The summary also states that soldeer.lock changed, but soldeer.lock is excluded from review. The required lock entry cannot be independently verified.
