chore: update dependencies, drop Node.js 18, add Node.js 22/24 support, and fix test compatibility (#214)

* fix: resolve security vulnerabilities in dependencies

- Upgrade esbuild from ^0.24.0 to ^0.25.0 to fix moderate severity CORS vulnerability
- Upgrade tar from ^7.5.6 to ^7.5.7 to fix high severity path traversal vulnerability
- Add yarn resolutions to fix transitive dependency vulnerabilities:
  - lodash ^4.17.23 (prototype pollution)
  - @octokit/request-error ^5.1.1 (ReDoS)
  - @octokit/plugin-paginate-rest ^9.2.2 (ReDoS)
  - @octokit/request ^8.4.1 (ReDoS)
  - js-yaml ^4.1.1 (prototype pollution)
  - brace-expansion ^2.0.2 (ReDoS)
  - tmp ^0.2.4 (symlink vulnerability)

All tests and linting pass with no breaking changes.
Fixes 16 security vulnerabilities (4 Low, 11 Moderate, 1 High).

* fix: remove TypeScript error suppression comments related to babel/types version mismatches

* chore: update dependencies and reduce resolutions to fix security vulnerabilities

- Update production dependencies (esbuild, into-stream)
- Update dev dependencies (release-it, @release-it/conventional-changelog, @types/node, rimraf, eslint-config-airbnb-typescript, lint-staged)
- Reduce resolutions from 7 to 2 (keep only lodash and undici for release-it compatibility)
- Add types:[] to tsconfig.json to prevent stub @types package inclusion
- Fix code formatting in test file

All security vulnerabilities resolved (0 vulnerabilities in yarn audit)

* chore: upgrade to release-it@19 and remove all resolutions

- Upgrade release-it from 18.0.0 to 19.2.4
- Remove all remaining resolutions (lodash, undici)
- Now using Node.js 22.22.0 which allows release-it@19.x
- Zero security vulnerabilities confirmed via yarn audit

* chore: drop support for Node.js 18 and add support for Node.js 22 across CI, tests, and documentation

* fix: resolve glob pattern in rimraf causing EINVAL on Windows

rimraf v4+ no longer accepts glob wildcards in paths. Use tinyglobby
to expand the pattern before passing resolved paths to rimraf.

* chore: add Node.js 24 to CI matrix and test targets

+# Plan: Drop node18 target, add node22 target
+
+## Context
+
+The project currently supports `node18` and `node20` as compilation targets (plus `host`). The user wants to drop `node18` and add `node22` instead, updating CI, source code, tests, and documentation accordingly.
+
+## Changes
+
+### 1. CI Workflows
+
+**`.github/workflows/ci.yml`**
+
+- Change build matrix from `[18.x, 20.x]` to `[20.x, 22.x]`
+- Change lint condition from `node-version == '18.x'` to `node-version == '20.x'`
+- Replace `test_18` job with `test_22` (calling `test:22`)
+- Keep `test_20` and `test_host`
+
+**`.github/workflows/test.yml`**
+
+- Change test matrix from `[18.x, 20.x]` to `[20.x, 22.x]`
+
+### 2. Package configuration
+
+**`package.json`**
+
+- Update `engines.node` from `>=18.0.0` to `>=20.0.0`
+- Replace `test:18` script with `test:22`: `"node test/test.js node22 no-npm"`
+- Update `test` script to call `test:22` instead of `test:18`
+
+### 3. ESM Transformer
+
+**`lib/esm-transformer.ts`** (line 379)
+
+- Change esbuild target from `'node18'` to `'node20'` (new minimum supported version)
+
+### 4. Tests
+
+**`test/test-42-fetch-all/main.js`** (line 18)
+
+- Change `nodeRanges` from `['node18', 'node20', 'node22']` to `['node20', 'node22']`
+
+**`test/test-50-fs-runtime-layer-3/main.js`** (lines 29-32)
+
+- The `node18`-specific branch is no longer needed. Since we only target node20+, the error message is always the ENOENT variant. Remove the `node18` conditional and use the `node20+` behavior unconditionally.
+
+### 5. Documentation & templates
+
+**`lib/help.ts`** (line 35)
+
+- Update example from `node16-linux,node18-linux,node18-win` to `node20-linux,node22-linux,node22-win`
+
+**`README.md`** (lines 56, 85)
+
+- Update example from `node16-linux,node18-linux,node18-win` to `node20-linux,node22-linux,node22-win`
+- Update target example from `node18-macos-x64` to `node20-macos-x64`
+
+**`.github/copilot-instructions.md`**
+
+- Update node version references (node18 -> node20, matrix mention, lint reference, engines note)
+
+**`.github/ISSUE_TEMPLATE/01_bug_report.yml`** and **`02_regression.yml`**
+
+- Update example targets from `node18` to `node20`
+
+## Verification
+
+1. `yarn build` — ensure TypeScript compiles cleanly
+2. `yarn lint` — ensure no lint errors
+3. `yarn test:host` — run host-target tests
+4. `yarn test:20` — run node20 target tests
+5. `yarn test:22` — run new node22 target tests
