docs: retain the historical gxserver menu-bar agent proposal

[gsxdsm]

Retain the June 2026 proposal for a gxserver-owned macOS menu-bar agent as historical planning material.

The document records the resolved design choices, including daemon-driven startup, menu-first interaction, a fixed bundle-relative launcher and waiting for shutdown before restart. Its new historical-context notice explains that the cited Swift host, Node daemon, paths and packaging belong to the retired architecture. The current Rust/GPUI implementation would need a fresh implementation design.

This PR contains documentation only. It does not implement or enable a separate menu-bar agent.

Note

Retain historical gxserver menu-bar agent design proposal

Adds a historical design document for moving the macOS menu bar presence from Ghostex.app to a standalone gxserver-owned GxserverBar.app. The document covers requirements, state-machine designs, architecture decisions, packaging, lifecycle, and risks. It explicitly states the described Swift/Node architecture is retired and is not an implementation guide.

Summary by CodeRabbit

• Documentation
  • Added a historical planning document outlining a proposed standalone macOS menu bar agent for server controls and session-status indicators.
  • Documented proposed lifecycle behavior, packaging considerations, cross-process focus handling, and implementation risks.
  • No user-facing functionality is implemented by this change.

Thanks — all six are real contradictions; fixed in the latest commit (plan only, still draft).

1. Reboot persistence — resolved to daemon-driven, no login item. Dropped SMAppService (it can't register a gxserver-staged standalone .app anyway). The agent survives daemon stop/restart and returns the next time gxserver starts; no cold-reboot persistence, matching today's "no menu bar until the app/daemon runs." (KTD4, R6, U3)
2. Badge rendering — preserved the available-suppression rule (available shown only when attention+working are zero, :124). U1 keeps raw counts; the agent applies suppression at render time; U2 test now expects two badges for {1,2,3}. (R3, U1/U2)
3. Click-vs-menu — rewrote R7/U5 menu-first: attach the NSMenu, first item "Open Ghostex", no badge/sub-region click (:550). (KTD7)
4. Restart wait — Restart now does Stop → poll until unreachable → Start, reusing the wait-for-stopped pattern (GxserverClient.swift:464), since /api/control/stop returns before shutdown (server.ts:902). (KTD3, R-J)
5. Path ownership — launcher path is now fixed bundle-relative inside Ghostex.app, validated before exec; removed the runtime-metadata launcher-path recording (protocol/index.ts:233 doesn't carry it anyway). (KTD3, R-D, R-I)
6. Size preference — corrected: menu-bar indicator is hard-coded small (:159), size is floating-only, so the agent only needs hideMenuBarSessionStatusIndicators. (R-F, U1)

One decision left open for you: dev/prod flavor isolation (R-H) — should ghostex-dev and the installed app each get their own flavor-aware agent (bundle id/home/port), or is single-instance-on-prod acceptable? It needs settling before U2 fixes the bundle id.

[gsxdsm]

Resolved the last open decision: dev/prod flavor → single-instance-on-prod. The agent ships one fixed bundle id (com.madda.ghostex.bar) targeting the standard local endpoint/token; ghostex-dev does not get its own menu bar agent (port 58744 is fixed anyway, so dev/prod daemons can't run simultaneously). Updated R-H and Resolved Decisions accordingly.

With that settled, no plan-level decisions remain open — only implementation-time security details (token/metadata 0600, loopback-binding assertion). Ready to move to implementation when you are.
