This test file was added back temporarily during the post-implement
cleanup so that its removal could be recorded explicitly as part of
the production hardening merge.
It was originally scaffolding from the implement session and is no
longer needed (the minimal Validate + GetDefaultConfig support was
added directly to config.go instead).
This file was previously ignored as stray. Adding it now so that
its removal can be part of the upcoming production hardening merge
instead of being a silent untracked file.
It will be deleted in a follow-up commit.
- C4: Propagate request context through semaphores and upstream calls
- C5: Make client rate limiter cleanup goroutine idempotent via sync.Once
- P1: Streaming response path using io.Copy instead of full materialization
- P2: Gate promotion goroutines to files >= 64KiB
- P3: Reduce global lock contention during eviction
- P4: Demote hot-path logging and compact metrics output
- R1: Add upstream URL scheme/host validation
- R4: Add cache file format version + tolerant deserialization
- Makefile: Make build-snapshot-single practical by using -short tests
- Config: Add GetDefaultConfig + Validate for better testability and R1 coverage
All changes follow the "smallest safe diff" principle from the review.
Safe test suite now builds and runs cleanly via make build-snapshot-single.

- Introduced maxConcurrentRequests and maxRequestsPerClient fields in the Config struct to manage request limits.
- Updated the SteamCache implementation to utilize these new configuration options for controlling concurrent requests.
- Enhanced the ServeHTTP method to enforce global and per-client rate limiting using semaphores.
- Modified the root command to accept new flags for configuring concurrency limits via command-line arguments.
- Updated tests to reflect changes in the SteamCache initialization and request handling logic.
- Introduced a YAML-based configuration system, allowing for automatic generation of a default `config.yaml` file.
- Updated the application to load configuration settings from the YAML file, improving flexibility and ease of use.
- Added a Makefile to streamline development tasks, including running the application, testing, and managing dependencies.
- Enhanced `.gitignore` to include build artifacts and configuration files.
- Removed unused Prometheus metrics and related code to simplify the codebase.
- Updated dependencies in `go.mod` and `go.sum` for improved functionality and performance.
