* feat(completion): execute dynamic generators for live candidates The completion engine consumed Fig specs' static shape but never ran their dynamic generators, so positions whose candidates come from the live system — ssh hosts, git branches — fell through to filesystem path completion (#51: ssh <Tab> listed the cwd). Local-only by design: the pure engine returns each pending script, the view runs it on the background executor (/bin/sh -c in the session cwd, 800ms timeout, kill-on-drop, 256KiB stdout cap, 5s TTL cache) and merges the parsed lines into the open menu, generation-tagged so a result can't outlive its session. A per-script parser registry ports the specs' dropped postProcess transforms (git markers, docker {{json .}}, package.json scripts, …); unmatched scripts default to one-candidate-per-line, and hopeless outputs are suppressed rather than inserted as garbage. ssh/scp/sftp/rsync specs gain host generators reading ~/.ssh/config (Include-aware, wildcard patterns skipped) and known_hosts (hashed entries skipped, [host]:port unwrapped). Fixes #51 Co-authored-by: l0ng-ai <24760907+l0ng-ai@users.noreply.github.com> * docs(comments): describe borrowed conventions directly Prior-art name-drops in comments aged poorly as the implementations diverged; keep the behavioral rationale, drop the product citations. * fix(completion): make generator execution CI-portable Linux: sh -c may fork the command instead of exec'ing it, so killing only the shell on timeout left a grandchild holding the stdout pipe — the reader (and the caller) then blocked until the grandchild exited on its own. Spawn the child as its own process-group leader and kill the group; the timeout test now forces the fork case (trailing true) so the group-kill is what's actually proven. Windows: generator scripts are POSIX sh + awk, so the execution path now compiles to no-suggestions there instead of failing at runtime on a missing /bin/sh; the process-spawning tests are Unix-only to match. --------- Co-authored-by: l0ng-ai <24760907+l0ng-ai@users.noreply.github.com>
