feat : Convert check scripts to Vitest in place

Convert check scripts to Vitest in place

Summary

Converts all 7 scripts/check-*.js check scripts from plain node:assert
scripts to Vitest test suites in place same files, same directory,
same filenames. This gives the reviewer a clean line-by-line diff showing
each assert.* call being replaced by its expect() equivalent.

Why in place?

The previous approach (delete old scripts + add new tests/integration/*.test.ts
files) made the PR unreviewable —

What changed

Each scripts/check-*.js file was mechanically converted:

Change	From	To
Test structure	Flat top-to-bottom script	describe() / test() blocks
Assertions	assert.equal(a, b)	expect(a).toBe(b)
	assert.deepEqual(a, b)	expect(a).toEqual(b)
	assert.match(a, /re/)	expect(a).toMatch(/re/)
	assert.doesNotMatch(a, /re/)	expect(a).not.toMatch(/re/)
	assert.ok(a)	expect(a).toBe(true)
	assert.notEqual(a, b)	expect(a).not.toBe(b)
	assert.throws(fn, /re/)	expect(fn).toThrow(/re/)
	assert.doesNotThrow(fn)	expect(fn).not.toThrow()
Imports	Top-level await import()	beforeAll(async () => ...)
Temp dirs	Single shared mkdtempSync	Per-test mkdtempSync (better isolation)
Console	console.log("...: ok")	Removed (Vitest reports pass/fail)

No test logic was changed. Every assertion, input data, regex pattern,
and expected value is identical to the previous implementation.

Files modified (7 scripts)

Script	Tests	What it covers
check-transcript-bundle.js	5	Codex/Claude/Copilot/OpenCode bundling, system instruction stripping, missing file error
check-repo-context.js	5	Non-git fallback, SSH/HTTPS remote parsing, default branch detection
check-install-options.js	8	Auto-save, guidance-only, no-hooks, opencode, copilot, flag validation, uninstalled repo error
check-graph-view.js	1	Rendering components without code anchors
check-proposal-validate.js	4	Malformed edges, missing kind, compact edges, repo-scoped graph objects
check-bm25-tokenizer.js	7	camelCase/PascalCase/snake_case/kebab-case tokenization, stemming, BM25 scoring
check-anchor-drift.js	5	Unchanged code, value change, comment-only, whitespace-only, no baseline

Infrastructure changes

• vitest.config.ts — new, targets scripts/check-*.js, excludes check-node-version.js
• package.json — test now runs npm run build && vitest run; added test:fast, test:watch, test:coverage
• package.json — added vitest and @vitest/coverage-v8 to devDependencies

Pre-existing build fix

While merging origin/main, discovered a pre-existing build breakage: libs/install/platforms/opencode.ts imported HookInput from ../../hooks/hook-input.js but commit #95 moved HookInput to ../../hooks/types.ts without re-exporting. Fixed the import to match the pattern used in openhands.ts:

// before (broken on main)
import { hookSessionId, type HookInput } from "../../hooks/hook-input.js";

// after
import { hookSessionId } from "../../hooks/hook-input.js";
import type { HookInput } from "../../hooks/types.js";

Verification

Test Files 7 passed (7)
Tests 35 passed (35)
Duration 3.16s

• npm test — build + full suite (CI default)
• npm run test:fast — skip rebuild, run tests only
• npm run test:watch — watch mode for development
• npm run test:coverage — coverage report
