emrg: TUI status bar shows full session id when session name exists

[argszero]

Host rant 2026-08-13T16:14:12.

Problem

_format_status_left (emrg/client/app.py:40) truncated the session id to 8 characters (sid[:8]) whenever a session title was present:
v0.2.30 emrg-main (s_260727) [model] — while the no-title form always showed the full id. Inconsistent and loses the ability to reference a session by its full id from the status bar.

Change

• emrg/client/app.py: sid[:8] → sid (full session id shown in the title form)
• tests/test_app_status_left.py: test_sid_truncated_to_8_chars → test_sid_full_in_title_form asserting the full id

Verification

• pytest 779 passed (full suite)
• import + CLI checks green

Verified: _format_status_left now shows the full session id in the title form (was sid[:8]), consistent with the no-title form which already showed the full id; test updated to assert full sid (s_260727abcdef); rant 2026-08-13T16:14:12 host request honored. CI test + test-windows SUCCESS (31681496296).

Tested end-to-end on 76a5f8b (Windows, py3.13): pytest 722 passed + 57 skipped (779) green. Code review clean — one-line change aligns the title-form with the no-title form (full sid), test updated in place with an accurate docstring citing rant 2026-08-13T16:14:12; test count unchanged so no doc-count sync needed. No blocking issues found.
