feat(sessions): offer the item you came from when starting a new session (#10940)

* fix: connect to dev server instead of localhost * fix: derive WebSocket scheme from location.protocol Mirror the protocol-aware pattern used by initSqlWebSocket in dev.ts so the WebSocket connects over wss:// when the dev server is reached through an HTTPS proxy/tunnel, avoiding mixed-content blocking. * refactor: drop now-unused port parameter of wmillTsDev Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HsfdN82yP88qyQ3h8Lwv2v * feat(sessions): offer the item you came from when starting a new session Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VkrstcgtV4AC4jZRHVzFdm * docs(sessions): state the new-session seed latch's real lifetime Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VkrstcgtV4AC4jZRHVzFdm * fix(sessions): let Enter act on the focused answer of the new-session offer Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VkrstcgtV4AC4jZRHVzFdm * feat(sessions): start on the item instead of resuming a stale session from the rail Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VkrstcgtV4AC4jZRHVzFdm * fix(sessions): hand the rail's item entry through the editor's own hand-off Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VkrstcgtV4AC4jZRHVzFdm * fix(sessions): snap the rail toggle back when a session switch does not navigate Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VkrstcgtV4AC4jZRHVzFdm --------- Co-authored-by: Nathan A.
