Release v0.7.5 · Dinosaur-MC/dsh-win-multi-bash

New

The terminal sessions now have a Session header panel, built like the first-party job list. One control beside the Session title lists every PTY session the deployment runs — running and finished — with a live count and an elapsed clock, and expands a row into its retained output. Stopping is a two-press action on running rows only; the panel is anchored to its trigger rather than overlay-ed, and it disappears when there is no session to show. Its /win-mb RPC (sessions.list, sessions.tail, sessions.stop) is registered on the root context through Connection, so the panel inherits that service's trust fence instead of inventing one.
An ended session stays readable, which it did not before. Reclaiming a session dropped the object together with its output ring, so a session stopped from the header or closed by the idle reaper became unreadable at once — the model got "is gone" and the row was gone with it. The last eight ended sessions are now retained with their windows: read and tail still answer, the header's finished section still expands, and an evicted id answers with the reason it left instead of pretending it never existed.

read waits when asked, and an empty answer always says why. A positive waitMs blocks until new output arrives and returns that delta; 0 stays an instant snapshot. Every empty result now carries no_output, timeout or session_exit — the row used to drop even the exit it received. all: true returns the whole retained window without moving the read cursor, and is refused together with offset or waitMs.
send and signal stop swallowing output that arrived between calls. Their delta now starts at the caller's cursor, not the ring head, so output produced between two calls is delivered instead of vanishing (it was neither in that call's result nor in any later read).
Startup no longer pays a timeout on a slow prompt. The readiness wait baselines at session birth by byte offset (an echo landing before the first poll no longer makes a silent command pay the whole budget), and DEFAULT_STARTUP_WAIT_MS moved from 4 s to 10 s: this repository's prompt runs git and the first prompt measured ~4.0 s, exactly on the old budget.

A reclaimed session no longer lists as running. A stopped or reaped session reported status: exited only after its provider settled done; until then the panel showed it under running with a stop button. The view now reports a reclaimed session as exited, while the internal status is left alone so close still reports the exit code its terminator produces.
A finished row's clock stops at the end. The panel computed every duration as now - startedAt, so a dead row kept counting up. Retention stamps lastActiveAt and a finished row's clock uses it; running rows keep ticking.
The blank line after every echoed command is gone. ConPTY sends a lone CR — a cursor return — before a command's output, and a CRLF can straddle two chunks; both became an extra line break. A line-leading CR is now dropped and a split CRLF is paired across chunks.
Reopening the header panel no longer jumps. The anchor survived a close, so the first frame painted at the previous position and the measurement moved it. The position is cleared on close and on open, so the first frame stays hidden until it is measured.

No breaking change to tool names, rows, config keys or existing results. all is a new optional read parameter, read now honours waitMs where it used to ignore it, and read results carry waitReason (with the new value no_output) where v0.7.4 returned none. The Session header panel registers on conversation.session.header.actions and needs the Connection service — a deployment without it registers nothing and the rest is unchanged.
Stated limit: the finished list holds eight sessions with their output rings (about 1 MiB each at most) in memory, evicted in ending order; an evicted id is no longer readable.
