Gleam v1.17.0 Adds Single-File Escript Export, Broadening Beyond Server Infrastructure

Gleam v1.17.0 introduced native escript compilation, bundling type-safe functional programs into single executable files for the Erlang runtime. The `gleam export escript` command packages all compiled bytecode into one distributable file, eliminating multi-file deployment complexity. This shifts Gleam's practical scope from distributed systems into command-line tooling and scripting domains where installation friction typically favors shell or dynamic languages.
