[Tests] Add tests (#26)

# Description

Adds a complete unit test suite for Sindri (195 tests, 52 files)
reaching 99.91% line coverage — 100% of all reachable lines, one test
file per source file. Also fixes two AST node-kind bugs in
`ConfigReader` that caused `readFile` to return an empty `ConfigResult`
for every real config and to miss `import.meta.dirname` directory
resolution.

## Changes

- **`src/Sindri/Ast/ConfigReader.ts`** — fixed two AST node-kind bugs:
`super()` callee is a `SuperKeyword` (not an `Identifier`), and
`import.meta` is a `MetaProperty` — the prior checks caused `readFile`
to return an empty `ConfigResult` for every real config and to miss
`import.meta.dirname` directory resolution
- **`tests/Tests/Unit/**` (52 files, 195 tests)** — added dedicated
per-source-file unit tests covering `AstReader` (via a `TestAstReader`
subclass exposing every protected helper), `GenerateDataFromAst`
(stubbed readers/generators + real `App` fixture tree, hitting every
dedup/skip/continue/recursion branch), `HttpRouteParameterReader`,
`HttpRouteMiddlewareReader`, `RouteAttributeReader`,
`AstHttpDataFileGenerator` (with `RequestMethod::`-prefixed methods and
a `Regex::NUM` parameter to populate path/regex builders), and targeted
edge-branch tests for `ServiceProviderReader`, CLI/HTTP attribute
readers, `ListenerAttributeReader`, and `ConfigReader`
- **`tests/Tests/Classes/`** — added inert ts-morph fixture trees
(config variants, providers, controllers, middleware, the `App` pipeline
tree, and `AstReader` helpers)
