emrg: GUI open-session dialog — name-or-id display + last-active time (rant 2026-08-21T11:41:07)

[argszero]

Summary

Fixes rant 2026-08-21T11:41:07 — GUI open-session dialog ("Open Session" → pick project → session list) two improvements:

1. Name-or-id display: showProjectSessions now renders s.title || s.session_id instead of s.title || _t("app.unnamed") — a titled session shows its title, an untitled session shows its full session id (no truncation, no "unnamed" fallback), consistent with the sidebar name-or-id rule (emrg: GUI session list — scoped highlight + name-or-id display (rants 22:04:02 + 22:04:57) #903).

2. Last-active time: each session row now shows a relative last-active time (relTime(s.updated_at), e.g. "5 分钟前" / "5 min ago") using the existing help-hint style and the updated_at field already returned by Session.list_sessions. The current-session marker ("当前") is preserved and joined with the time.

Changes

• emrg/gui/renderer/js/dialogs.js — showProjectSessions() row rendering (name-or-id + relTime hint)
• emrg/gui/test/renderer.smoke.test.js — new test: titled → title; untitled → full id (no "未命名"); relTime shown for updated_at; missing updated_at → id only
• Agent.md — GUI test breakdown synced to real counts (256: renderer smoke 126→127, integration 7→8 — the integration count already lagged by one before this PR)

Verification

• GUI: npm test — 256 tests, 248 pass, 8 skipped (live daemon owns fixed port), 0 fail
• Python: uv run pytest tests/ — 987 passed + 1 skipped (incl. doc-count guards)
• python -m emrg --help + import OK

✅ LGTM — cycle

Fresh review of the open-session dialog changes:

• showProjectSessions renders s.title || s.session_id (name-or-id, full id, no truncation) per the sidebar rule from #903; removes the _t("app.unnamed") fallback for untitled sessions.
• Last-active time via relTime(s.updated_at) (returns "" for missing/invalid), joined with the current-session marker using existing help-hint styling.
• New smoke test covers: titled → title shown; untitled → full session id shown (no "未命名"); relTime text for 5-min and 2-hour updated_at; missing updated_at → id only, no time.
• Agent.md GUI breakdown synced to real counts (256 total: renderer smoke 126→127, integration 7→8 pre-existing lag).
• Verified: GUI npm test 256 (248 pass + 8 skipped, live daemon owns port), Python pytest 987 passed + 1 skipped incl. doc-count guards, import + CLI OK. CI test + test-windows PASS.

Re-review (head 2ac7f98 unchanged since previous review):

• showProjectSessions renders s.title || s.session_id — titled sessions show title, untitled sessions show full session id (no truncation, no "未命名" fallback), consistent with the sidebar name-or-id rule (#903).
• Last-active time: relTime(s.updated_at) returns "" for missing/invalid dates (safe), joined with the current-session marker via marks.join(" · ") in the existing help-hint style.
• Test covers all three cases: titled (title + 5-min relTime), untitled (full id + 2-hour relTime, no 未命名), and missing updated_at (id only, no time).
• Agent.md GUI breakdown synced to real node test-runner counts (256: renderer smoke 126→127, integration 7→8 pre-existing lag corrected).
• Verified locally: GUI npm test 256 (248 pass + 8 skipped, live daemon owns fixed port), Python pytest 987 passed + 1 skipped (incl. doc-count guards), import + CLI OK. CI test + test-windows PASS.

3rd consecutive review (head 2ac7f98, MERGEABLE/CLEAN, CI test + test-windows PASS):

• Fresh local verification on the branch: GUI npm test 256 total (248 pass / 0 fail / 8 skipped — live daemon owns fixed port), pytest 987 passed + 1 skipped, import + CLI OK.
• showProjectSessions renders s.title || s.session_id — titled sessions show title, untitled sessions show the full session id (no truncation, no "未命名" fallback), consistent with the sidebar name-or-id rule (#903).
• Last-active time via relTime(s.updated_at) (helper exists in utils.js, exposed on window); current-session marker preserved, joined with '·'.
• Tests cover titled/untitled/missing-updated_at rows incl. negative no-time case; Agent.md GUI counts synced (254→256).
