simple-http-server: starije verzije za preuzimanje

• Compared to the previous Iron-based version, this release changes the server in these ways:
Core
- Replaced the old iron stack with an axum + tokio implementation.
- Kept the CLI mostly compatible, but moved the codebase to a modern async HTTP stack.
- Reorganized the implementation into separate modules for config, server setup, handlers, and utilities.
TLS
- TLS support is now behind a single tls feature and is disabled by default.
- --cert and --certpass still accept PKCS#12 files, but they only work when the binary is built with --features tls.
- On Linux and macOS, TLS uses system OpenSSL.
- On Windows, TLS uses vendored OpenSSL to avoid CI and toolchain issues.
User-visible behavior changes
- --upload-size-limit now supports human-readable values such as 30K, 50M, and 1G.
- Size suffixes are interpreted in powers of 1024.
- Upload limit errors are clearer: oversized uploads now return a readable 413 message instead of low-level stream errors.
- Invalid multipart requests now return proper client errors instead of collapsing into 500 responses.
- Internal 500 errors are now printed to stderr for easier debugging.
- --open now uses https:// automatically when TLS is enabled.
- --base-url is normalized consistently.
- --try-file behavior is explicit: relative paths resolve against the server root, absolute paths are used as-is.
- CORS preflight OPTIONS requests are handled directly.
- Error pages escape injected text.
Performance and resource usage
- File responses are streamed instead of being buffered in full.
- Compressed responses are streamed.
- Uploads are streamed to temporary files instead of being fully buffered in memory.
- Temporary upload files are cleaned up on multipart failures, including size-limit failures.
Behavioral compatibility notes
- Most existing flags and main server behavior remain aligned with the old version.
- Colored request logging from the old implementation was removed.
- Some historical edge-case behavior from the Iron middleware chain, especially around HEAD + compression, was intentionally cleaned up rather than preserved exactly.
Quality
- Added black-box HTTP tests for directory listing, try-file, basic auth, range requests, cache revalidation, CORS preflight, uploads, and gzip compression.
- The new implementation passes tests and clippy in both default and tls builds.****

- Bump open version from 1 to 5
