הורדת usage 7.1.0

This release adds usage-spec-effect, a new npm package that turns Effect v4 effect/cli command trees into usage specs. It also fixes bash completions from usage-argv, which could pass the command a different value than the one offered when a candidate contained quotes, spaces or other shell syntax.
Added
- (spec) usage-spec-effect exports a usage spec from an Effect v4 effect/cli command tree (#1564, @jdx). Effect still parses and runs the CLI, and the spec drives shell completions, markdown docs and man pages. It requires effect 4.x.
npm install usage-spec-effect
import { generate } from "usage-spec-effect";
if (process.argv.includes("--usage-spec")) {
process.stdout.write(generate(app, { version: "1.0.0" }));
process.exit(0);
}
mycli --usage-spec | usage generate completion bash mycli --file -
The exporter handles nested subcommands, aliases, unlisted commands, examples, shared flags (exported as global), flag aliases, boolean and valued flags, choices, defaults, and optional and variadic args. Some constructs can only be exported approximately: orElse alternatives, file, redacted and key-value types (exported as strings), non-primitive defaults, and flags with an optional value. generateWithReport returns these in an unsupported list so they aren't dropped without notice. Effect's public Command type doesn't expose flags or arguments, so the exporter reads the command's runtime config. If a future Effect release changes that shape, generate throws an error that names the command. See the Effect integration guide.

Fixed
- (bash) usage-argv and usage-dynamic now escape bash completion candidates so the command gets the value that was offered (#1566, @jdx). Before this fix, Readline put candidates on the line unescaped, so a candidate like tasks."hello.sh" reached the command as tasks.hello.sh, and it's here left an unclosed quote on the line. Candidates are now backslash-escaped. When a quote is already open in the word (', " or $'), each candidate is escaped for that quote style instead. Path completions still use Readline's own filename quoting, and zsh and fish were already correct. Hosts handling __complete_word__ should call render_request(&answer, &request) instead of render(&answer, shell) so the open-quote state is used. App::completion_request in usage-dynamic already does this. The script-based bash completions behind usage complete-word are unchanged, since compgen -W can't carry spaces or quotes in candidates.
