(Minor): Updated changelog.md

CHANGELOG.md

@@ -37,6 +37,7 @@ first public release
 - **readme overhaul** — rewrote for clarity: added "what problem does this solve", "how it works", known issues, simpler install instructions, and proper dependency listing
 - **view cleanup** — removed the non-functional automata background overlay from `View()` (the `Frame()` was never called, and the black-space placeholder caused `EEEE` garbage characters on some terminals). also removed a hardcoded 80-char width on the top bar so it adapts to the terminal
 - **session environment setup** — `spawnSession` now calls `SetBasicVariables`, `SetDisplay`, `SetSessionParams`, `SetSeatVars`, `SetSessionVars`, and `SetXDGCommonPaths` before spawning the desktop. fixes `setupX` failing immediately with `missing DISPLAY/XDG_VTNR/HOME env vars` because none were set
+- **pam session error made non-fatal** — `pam_open_session` failure (e.g. `pam_systemd` rejecting the DM process as session leader) is now logged as a warning instead of blocking the entire session spawn. also removed `session include login` from `latchd.pam` since the DM process can't register user sessions with systemd-logind
