v0.0.8 — More reliable local time-zone detection

This release improves time-zone detection across Windows and Unix systems, while making the Windows mapping generator safer and easier to maintain.

Highlights

• Windows now uses the native GetDynamicTimeZoneInformation API first, avoiding a subprocess during normal detection and improving handling when automatic daylight-saving adjustments are disabled.
• The tzutil fallback no longer causes a console window to flash in GUI and detached applications ([#15](thlib/go-timezone-local#15), thanks [@​williammartin](https://github.com/williammartin)).
• Unix detection now handles relative /etc/localtime targets and symlinked parent directories more reliably. Time-zone extraction from zoneinfo paths was also simplified ([#17](thlib/go-timezone-local#17), thanks [@​dolmen](https://github.com/dolmen)).
• TZ environment values with the optional POSIX : prefix, such as :Europe/Tallinn, are now recognized correctly.
• Added a runnable example demonstrating detection and loading of the resulting IANA time zone.

Mapping generator improvements

• Replaced the legacy IANA FTP downloader with HTTPS.
• Added download timeouts, response-size limits, HTTP status checks, and input validation.
• Improved archive extraction errors and generated-code formatting.
• Refreshed the Windows-to-IANA mapping and removed an invalid empty mapping.
• Live network tests are now opt-in through TZLOCAL_LIVE_TESTS=1.

Compatibility note

The public tzlocal API is unchanged. The exported tzdata.FTPDownload helper was removed; this only affects programs importing that generator-oriented helper directly.
