refactor: move brother_node development artifact to dev/test-nodes subdirectory

Development Artifact Cleanup:
✅ BROTHER_NODE REORGANIZATION: Moved development test node to appropriate location
- dev/test-nodes/brother_node/: Moved from root directory for better organization
- Contains development configuration, test logs, and test chain data
- No impact on production systems - purely development/testing artifact

✅ DEVELOPMENT ARTIFACTS IDENTIFIED:
- Chain ID: aitbc-brother-chain (test/development chain)
- Ports: 8010 (P2P) and 8011 (RPC) - different from production
- Environment: .env file with test configuration
- Logs: rpc.log and node.log from development testing session (March 15, 2026)

✅ ROOT DIRECTORY CLEANUP: Removed development clutter from production directory
- brother_node/ moved to dev/test-nodes/brother_node/
- Root directory now contains only production-ready components
- Development artifacts properly organized in dev/ subdirectory

DIRECTORY STRUCTURE IMPROVEMENT:
📁 dev/test-nodes/: Development and testing node configurations
🏗️ Root Directory: Clean production structure with only essential components
🧪 Development Isolation: Test environments separated from production

BENEFITS:
✅ Clean Production Directory: No development artifacts in root
✅ Better Organization: Development nodes grouped in dev/ subdirectory
✅ Clear Separation: Production vs development environments clearly distinguished
✅ Maintainability: Easier to identify and manage development components

RESULT: Successfully moved brother_node development artifact to dev/test-nodes/ subdirectory, cleaning up the root directory while preserving development testing environment for future use.

+
+## Install
+
+```bash
+npm install get-tsconfig
+```
+
+## Why?
+For TypeScript related tooling to correctly parse `tsconfig.json` file without depending on TypeScript.
+
+## API
+
+### getTsconfig(searchPath?, configName?, cache?)
+
+Searches for a tsconfig file (defaults to `tsconfig.json`) in the `searchPath` and parses it. (If you already know the tsconfig path, use [`parseTsconfig`](#parsetsconfigtsconfigpath-cache) instead). Returns `null` if a config file cannot be found, or an object containing the path and parsed TSConfig object if found.
+
+Returns:
+
+```ts
+type TsconfigResult = {
+
+    /**
+     * The path to the tsconfig.json file
+     */
+    path: string
+
+    /**
+     * The resolved tsconfig.json file
+     */
+    config: TsConfigJsonResolved
+}
+```
+
+#### searchPath
+Type: `string`
+
+Default: `process.cwd()`
+
+Accepts a path to a file or directory to search up for a `tsconfig.json` file.
+
+#### configName
+Type: `string`
+
+Default: `tsconfig.json`
+
+The file name of the TypeScript config file.
+
+#### cache
+Type: `Map<string, any>`
+
+Default: `new Map()`
+
+Optional cache for fs operations.
+
+#### Example
+
+```ts
+import { getTsconfig } from 'get-tsconfig'
+
+// Searches for tsconfig.json starting in the current directory
+console.log(getTsconfig())
+
+// Find tsconfig.json from a TypeScript file path
+console.log(getTsconfig('./path/to/index.ts'))
+
+// Find tsconfig.json from a directory file path
+console.log(getTsconfig('./path/to/directory'))
+
+// Explicitly pass in tsconfig.json path
+console.log(getTsconfig('./path/to/tsconfig.json'))
+
+// Search for jsconfig.json - https://code.visualstudio.com/docs/languages/jsconfig
+console.log(getTsconfig('.', 'jsconfig.json'))
+```
+
+---
+
+### parseTsconfig(tsconfigPath, cache?)
+
+Parse the tsconfig file provided. Used internally by `getTsconfig`. Returns the parsed tsconfig as `TsConfigJsonResolved`.
+
+#### tsconfigPath
+Type: `string`
+
+Required path to the tsconfig file.
+
+#### cache
+Type: `Map<string, any>`
+
+Default: `new Map()`
+
+Optional cache for fs operations.
+
+#### Example
+
+```ts
+import { parseTsconfig } from 'get-tsconfig'
+
+// Must pass in a path to an existing tsconfig.json file
+console.log(parseTsconfig('./path/to/tsconfig.custom.json'))
+```
+
+---
+
+### createFileMatcher(tsconfig: TsconfigResult, caseSensitivePaths?: boolean)
+
+Given a `tsconfig.json` file, it returns a file-matcher function that determines whether it should apply to a file path.
+
+```ts
+type FileMatcher = (filePath: string) => TsconfigResult['config'] | undefined
+```
+
+#### tsconfig
+Type: `TsconfigResult`
+
+Pass in the return value from `getTsconfig`, or a `TsconfigResult` object.
+
+#### caseSensitivePaths
+Type: `boolean`
+
+By default, it uses [`is-fs-case-sensitive`](https://github.com/privatenumber/is-fs-case-sensitive) to detect whether the file-system is case-sensitive.
+
+Pass in `true` to make it case-sensitive.
+
+#### Example
+
+For example, if it's called with a `tsconfig.json` file that has `include`/`exclude`/`files` defined, the file-matcher will return the config for files that match `include`/`files`, and return `undefined` for files that don't match or match `exclude`.
+
+```ts
+const tsconfig = getTsconfig()
+const fileMatcher = tsconfig && createFileMatcher(tsconfig)
+
+/*
+ * Returns tsconfig.json if it matches the file,
+ * undefined if not
+ */
+const configForFile = fileMatcher?.('/path/to/file.ts')
+const distCode = compileTypescript({
+    code: sourceCode,
+    tsconfig: configForFile
+})
+```
+
+---
+
+### createPathsMatcher(tsconfig: TsconfigResult)
+
+Given a tsconfig with [`compilerOptions.paths`](https://www.typescriptlang.org/tsconfig#paths) defined, it returns a matcher function.
+
+The matcher function accepts an [import specifier (the path to resolve)](https://nodejs.org/api/esm.html#terminology), checks it against `compilerOptions.paths`, and returns an array of possible paths to check:
+```ts
+function pathsMatcher(specifier: string): string[]
+```
+
+This function only returns possible paths and doesn't actually do any resolution. This helps increase compatibility wtih file/build systems which usually have their own resolvers.
+
+#### Example
+
+```ts
+import { getTsconfig, createPathsMatcher } from 'get-tsconfig'
+
+const tsconfig = getTsconfig()
+const pathsMatcher = createPathsMatcher(tsconfig)
+
+const exampleResolver = (request: string) => {
+    if (pathsMatcher) {
+        const tryPaths = pathsMatcher(request)
+
+        // Check if paths in `tryPaths` exist
+    }
+}
+```
+
+## FAQ
+
+### How can I use TypeScript to parse `tsconfig.json`?
+This package is a re-implementation of TypeScript's `tsconfig.json` parser.
+
+However, if you already have TypeScript as a dependency, you can simply use it's API:
+
+```ts
+import {
+    sys as tsSys,
+    findConfigFile,
+    readConfigFile,
+    parseJsonConfigFileContent
+} from 'typescript'
+
+// Find tsconfig.json file
+const tsconfigPath = findConfigFile(process.cwd(), tsSys.fileExists, 'tsconfig.json')
+
+// Read tsconfig.json file
+const tsconfigFile = readConfigFile(tsconfigPath, tsSys.readFile)
+
+// Resolve extends
+const parsedTsconfig = parseJsonConfigFileContent(
+    tsconfigFile.config,
+    tsSys,
+    path.dirname(tsconfigPath)
+)
+```
