fix: fix all broken builds and tests across the repo

Native tests (16/16 passing):

- counter/native & escrow/native: add bn.js as explicit dependency.
  pnpm's strict dependency resolution does not hoist transitive deps
  (unlike npm), so bn.js from @solana/web3.js is not accessible directly.

- All native tests using borsh: migrate from borsh v0.7 class-based API
  to borsh v2 object schema API. The v0.7 API (Map schemas, Assignable
  classes, 3-arg deserialize) is incompatible with borsh v1+. Updated 19
  test files and 14 package.json files. Introduced a shared
  borshSerialize(schema, data) helper to replace the repeated
  Buffer.from(borsh.serialize(...)) pattern. Removed per-schema typed
  wrappers in favour of exporting schemas directly.

- create-account/native: replace litesvm with solana-bankrun. litesvm's
  native binary crashes with SIGABRT on Linux x64
  (LiteSVM/litesvm#171). This was the only
  native test using litesvm — all others use solana-bankrun, the
  recommended framework per CONTRIBUTING.md.

Anchor builds (39/39 passing):

- Set solana_version = "3.1.8" in all 49 Anchor.toml files. Anchor's
  default BPF toolchain ships rustc 1.79, but anchor-lang 0.32.1's
  dependency tree requires rustc 1.82+ (indexmap 2.13.0) and Cargo's
  edition2024 feature. Solana 3.1.8 platform-tools v1.52 (rustc 1.89)
  resolves both. All projects now use a consistent toolchain version.

- allow-block-list-token: bump spl-transfer-hook-interface 0.8.2 -> 2.1.0,
  spl-tlv-account-resolution 0.8.1 -> 0.11.1, spl-discriminator 0.3 -> 0.5.1.
  Old SPL versions used solana-program v1, causing type mismatches with
  anchor-lang 0.32.1's v2 types. litesvm Rust test moved to tests-rs/
  because litesvm pins solana-account-info =2.2.1 but anchor-lang 0.32.1
  needs >=2.3.0 for AccountInfo::resize(). See tests-rs/README.md.

Compression projects (3/3 building):

- Rewrite cnft-burn, cnft-vault, cutils from anchor-lang 0.26.0 to 0.32.1.
  Upgrade to mpl-bubblegum 2.1.1 + spl-account-compression 1.0.0 (both
  use solana-program v2, matching anchor-lang 0.32.1). cnft-vault: manual
  invoke_signed rewritten to TransferCpi. cutils verify: raw invoke because
  spl-account-compression 1.0.0's CPI module is built against anchor-lang
  0.31, which has incompatible traits with 0.32.1. Discriminator computed
  from sha256("global:verify_leaf") rather than hardcoded. Comment
  documents when this workaround can be removed.

Documentation:

- README: remove TypeScript/Poseidon references (none exist in repo),
  Anchor before Native in badges, fix typos.
- CONTRIBUTING: remove Steel/Python/Solidity/Poseidon references (none
  exist in repo), fix markdown, renumber sections.
