fix(coding-agent): always render inactive sessions in the agents view

[snimu]

Fixes RES-1316

Purpose

Inactive sessions must always render in the agents view; search is the filter. This partially reverts #2087's inactive-collapse ("Collapsed inactive sessions by default. Search still includes them; Alt+I toggles the section."), which was merged via the #2068 consolidation. Beyond the product decision, the Alt+I toggle is unreachable on default macOS terminals: the composed character goes to the always-focused search editor, so users could not reveal the hidden sessions.

Changes (surgical revert of one feature; everything else from the #2068 consolidation stays)

• compactSessionRows no longer gates depth-0 blocks on the inactive section; it keeps folding subagent-summary rows (that folding serves the running-subagents display items, which remain).
• Both call sites lose the showInactive plumbing (the query no longer doubles as a reveal switch — it filters, as before the collapse).
• Removed the app.agents.inactiveCollapse keybinding (type map + alt+i default), its input handler, the Inactive-header ▸/▾ prefix + Alt+I hint, and the actions-panel line.
• Removed persistentState.inactiveExpanded (writer + type). The state object is in-process only — it is never serialized to disk — so a stale property from an older view instance is simply never read; nothing needs migration.

Tests

• Flipped the collapse pin to the new contract: inactive rows render immediately with fresh persistent state (fails on current main), a stale inactiveExpanded: false is ignored, the old Alt+I chord hides nothing, and search still narrows to matches only.

LOC

Total src: +7/−36 (net -29); tests: +10/−12 (net -2). Net-negative surgical revert: the inactive-collapse gating, alt+i keybinding, header hint, actions line, and persisted flag deleted; kept consolidation features untouched. +1 changelog fragment.

Validation

• npm run check green (pre-commit hook).
• agents-view-mode (36), agents-view-state (77), 502 regressions (15), keybinding-hints green; reverting the src hunks fails exactly the flipped pin.

Note

Low Risk
Agents-view UI and list filtering only; no auth, daemon protocol, or persistence migration changes.

Overview
Inactive sessions are always visible in the agents view; the Alt+I collapse toggle is removed because it was hard to reach when search input captures keys on macOS.

Row building no longer hides the inactive section: compactSessionRows only drops subagent-summary rows, and search text filters the list instead of acting as a reveal switch. UI cleanup removes the inactive header ▸/▾ affordance, the actions-panel hint, and app.agents.inactiveCollapse from keybindings. inactiveExpanded is dropped from in-process persistent state (stale values are ignored).

Tests now assert inactive rows appear on load, Alt+I does nothing, and only a non-matching search hides them.

Note

Always render inactive sessions in agents-view-mode

Removes the collapse/expand toggle for inactive sessions in the agents view so they always render. Search remains the only way to filter sessions out.

• Deletes the app.agents.inactiveCollapse keybinding (Alt+I) from keybindings.ts and the inactiveExpanded persistent-state property from agents-view-mode.ts
• Strips the showInactive parameter from compactSessionRows; inactive top-level rows are always retained and only subagent-summary rows are folded
• Removes collapse/expand markers and the Alt+I hint from section headings and the actions panel
• Risk: any persisted inactiveExpanded state from older sessions is now ignored; no migration is performed, but the stale value has no effect
