Add @deepseek-ai/dsh-tmux-context: an opt-in per-turn context plugin that
reads which tmux session/window/pane this agent process runs in (plus the
window layout tree) via the ctx.bash seam, and injects it as one durable,
source-attributed user/message when the location changes.
- Pull on the first step of each turn; no tmux hook or background process.
- Detect a real pane by tty, not $TMUX_PANE alone: a terminal launched from
a tmux shell inherits $TMUX/$TMUX_PANE from that ancestor, so the command
also matches the pane's #{pane_tty} against this process's controlling
terminal and emits fields only on a match.
- No-op outside a real pane, without a bash executor, or on a malformed
reading.
- Own location and layout only: no pane sizes, no sibling-pane scraping.
- Unit tests at 100% per-file coverage, plus a keyless Loader e2e with a
mock bash provider so it replays without tmux.
- Agent Note: 2026-07-27-tmux-location-context.
