Sublime Text 4213 moves the plugin host to Python 3.14 and disables the 3.3 host by default

Sources: primary, discussion
Summary: The changelog states the plugin host is upgraded from Python 3.8 to Python 3.14, and that the 3.3 host is turned off by default behind the disable_plugin_host_3.3 setting, with removal in a future version stated. It also raises the supported platform floor to Windows 10 and macOS 10.13.
Why it matters: Plugin authors carry the migration, because a plugin targeting the 3.3 host does not load on a default install of this release unless disable_plugin_host_3.3 is set to false, while plugins written for the 3.8 host now run under the 3.14 interpreter.
