feat: inline pinned tabs in TabBar (replaces PinnedRail)
M4 rewrite per user feedback: pinned terminals should display in the
Tabs bar itself, not a separate rail. Clicking activates in-place
(cross-session terminal rendering), no session jump.
Changes:
- Delete PinnedRail.tsx + tests/pinned-rail.spec.tsx
- pinned.ts: add createPinnedVirtualTab (virtual id = pinned:<sess>:<id>,
meta.__pinnedHome = { sessionId, cwd, tabId }), injectPinnedIntoTree
(appends virtual tabs to first leaf, overrides active), isPinnedVirtualId,
parsePinnedVirtualId, isPinnedVirtualTab, getPinnedHomeScope
- tab-content-memo.ts: add effectiveTabId to memo key — TabContent passes
the original tab id (not the virtual id) to the descriptor component so
TerminalView's WS URL resolves to the home PTY
- Sidebar.tsx: augmented tree (injectPinnedIntoTree), activePinnedTabId
state, wrappedActions (intercept virtual ids for activate/close/unpin/
drag/float), renderTab passes home scope + effectiveTabId for pinned tabs,
pinnedRevision replaces railRevision
- TabBar.tsx: pinned virtual tabs non-draggable, pin icon prefix, stripped
context menu (Unpin/Close only, no float/close-others/left/right)
- sidebar.module.css: remove rail styles, add .pinnedTab (italic + tertiary)
- Docs: README/README_EN/AGENTS.md/design doc updated for inline approach
157/157 client-side tests pass; typecheck + build clean
