fix(client): clear the test debt — 2 production bugs, suite fully green (T-973 et al.)

Production fixes surfaced by honest test triage:
- hud_groups.gd: _set_group_z crashed on freed HUD nodes — the typed loop
  variable errors before the is_instance_valid guard runs; prune first
- fog_state.gd: _resize cleared _prev_visible (world-space keys survive
  resizes), so pre-resize tiles never decayed VISIBLE→EXPLORED (D-059)

Test debt (T-928/929/934/935/936/937/938/939, T-864, T-973): lambda
local-capture bugs rewritten with array captures (now assert exact
emission counts), e2e suites updated to the current handshake +
StartupMessage protocol and stream-aware reads against the live binary,
fog perf test measures steady state, chime test pins the shipped 800ms
catalog asset (D-067 amended separately), monologue gdUnit4 API typo,
battery-warning tests follow the MetaScreen on_open lifecycle. 3 sprint2
proof tests revived (corner_reveal had passed from the wrong tile — NPC3
blocks (18,14); route corrected). Soft-skips converted to real do_skip
reporting. T-1068: 7 orphan .gd.uid deleted, _format_pop/_format_radius
deduped into atlas_format.gd (preload, no class_name — headless cache).

Suite: 1264 cases/20 failures → 1268/0, independently re-verified
(2536/2536, exit 0).
