The zellij wrapper (functions/zellij.fish) rewrote every `zellij`
invocation as `zellij options --theme catppuccin-mocha <args>`, which is
only valid for launching a new session. This mangled every subcommand,
including the `zellij action dump-screen` call inside _zellij_dump_log,
so no logs were ever produced. The theme is already set in config.kdl,
making the wrapper redundant — remove it.
Also harden _zellij_dump_log:
- dump-screen takes the file via stdout redirect, not a positional arg
(rejected by zellij 0.44) nor --path (server-side write, flaky)
- add --ansi to preserve color in the logs
- discard empty dumps instead of leaving junk files
Document the structural limitation: zellij can only snapshot on a clean
shell exit, unlike tmux's continuous pipe-pane stream. Closing a pane or
quitting zellij tears down the pane/server before it can be dumped.
