v0.4.1

fish 4.0+ now records with zero configuration

fish 4.0 started emitting full OSC 133 shell-integration marks natively — including the command line itself, attached to the C mark as a percent-encoded cmdline_url parameter (kitty shell-integration protocol). backscroll now parses that, so on fish ≥ 4.0:

backscroll run

…just works. No snippet in config.fish, nothing sourced. Command text, exit codes (including 130 on Ctrl-C), cwd, multiline blocks, and the end-of-session exit stub-drop all behave exactly as with the snippet.

The snippet is still worth having for the Ctrl-X Ctrl-P picker binding and tab completion — and running both is fine: duplicate C/D marks collapse, and the snippet's exact command text takes precedence over the native hint.

Also in this release

• New recorder-level E2E test suite driving a real fish 4.8.1 on a PTY (shell/test_fish4_native.py), covering both the native-marks-only and double-emission scenarios; runs in CI against a cached fish 4.8.1 static binary. The harness answers reedline's startup terminal probes (DA1, DSR 6n, OSC 11) like a real terminal.
• docs/osc133.md: documented fish 4's native marks + cmdline_url, and a new gotcha on making duplicate marks collapse (with observed ordering: native C;cmdline_url arrives before fish_preexec handlers run).

Compatibility

• No schema change; DBs from 0.4.0 are untouched.
• Older binaries simply ignore cmdline_url (fish ≥ 4.0 sessions record as (unknown command) there).
