This makes the existing get_cwd/get_cwds polling O(panes) instead of O(host processes) and unblocks doing the same for foreground-command discovery. * perf: discover foreground pane commands w/o scanning all processes Foreground command discovery was reading information about every process on the host, on each pane/tab creation and on every periodic poll. On hosts with many processes (eg, 50k) this stalled pane creation for tens of seconds and overran the action-completion timeout. Replace that O(host processes) lookup with an O(panes) lookup. Instead of looking up the parent pid of every process to find the child, get the foreground process-group leader's pid from a call to tcgetpgrp on the pane's controlling terminal. When the leader is the shell itself (idle prompt or a command sharing the shell's group without job control) the pane is omitted and the caller falls back to the shell command, matching prior behavior; with job control on it now reports the true foreground job instead of possibly a background one. This changes the paths for Linux, macOS, and BSD. It leaves Windows unchanged. * refactor(os_input): extract apply_post_command_hook helper The command -> run_command_hook -> trim/split pipeline was duplicated between the #[cfg(not(unix))] get_all_cmds_by_ppid and the unix get_foreground_cmds. Extract a single apply_post_command_hook helper and call it from both sites, routing the hook-failure fallback through the project's non_fatal() logging idiom (CONTRIBUTING.md "Logging errors") instead of log::error!. * review: simplify tcgetpgrp locking, trim comments, drop changelog entries - Remove the lock-drop dance and its TOCTOU caveat from tcgetpgrp, to make it mirror tcdrain - Prune AI comments - Remove CHANGELOG entries 2026-04-17T12:08:48Z Aram Drevekenin aram@poor.dev 2026-04-17T12:08:48Z urn:sha1:aa29cbaf6631af0afca6aae427a97b3e478393b3 * initial implementation * fix mouse cpu spam * prevent excess metadata write and prune sessions on startup * consolidate CommandChanged and PaneCommandChanged * tests * rustfmt * add pr
