feat(basics): migrate remaining 29 programs from ts-mocha to tsx + node:test runner

[NikkiAung]

Summary

Follow-up to #636 (pilot). Applies the same ts-mocha → tsx --test migration to all remaining non-anchor native/pinocchio/asm programs in basics/ (29 programs, 94 files).

Anchor programs excluded — anchor test --validator legacy invokes mocha internally and bypasses package.json scripts entirely; migrating them requires changes to the Anchor CLI itself.

Changes per program (×29)

• package.json — test script: pnpm ts-mocha … <file> → tsx --test <file>; drop mocha/ts-mocha/@types/mocha/chai/@types/chai; add tsx ^4.22.0 + @types/node ^22.19.1
• tsconfig.json — types: drop "mocha" and "chai", ensure "node" is present
• pnpm-lock.yaml — regenerated per package (mocha/chai tree removed, tsx added)

6 test files with structural edits

File	What changed
cross-program-invocation/native	Add node:test imports (before, describe, test); rename it() → test()
cross-program-invocation/pinocchio	Same; also swap import { assert } from "chai" → import assert from "node:assert"
hello-solana/asm	Add node:test imports (before, describe, test); rename it() → test(); chai → node:assert
hello-solana/pinocchio	Same as hello-solana/asm
favorites/native	import { describe, test } from "mocha" → node:test; add beforeEach; chai → node:assert; expect().to.equal → assert.strictEqual, expect().to.deep.equal → assert.deepStrictEqual
favorites/pinocchio	import { describe } from "mocha" → node:test (stub file)

Note: favorites/native and cross-program-invocation/native remain in .ghaignore — migrations are for correctness/consistency, not yet CI-verified.

Test plan

• CI solana-native.yml passes for all native programs in this PR
• CI solana-pinocchio.yml passes for all pinocchio programs
• CI solana-asm.yml passes for create-account/asm and transfer-sol/asm
• Grep: no residual ts-mocha, from "mocha", or from "chai" in migrated programs

Greptile Summary

This PR migrates the remaining non-Anchor basics tests to Node’s built-in test runner. The main changes are:

• Replaces ts-mocha test scripts with tsx --test.
• Replaces Mocha and Chai dependencies with tsx and Node types.
• Converts six test files to node:test and node:assert.
• Regenerates each affected package lockfile.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The explicit Node test imports preserve the existing suite and hook behavior.
• The converted assertions preserve the tested value comparisons.
