Updates the manual walkthrough to reflect the full state of the branch
after rebase + banner padding fix + pre-send validation fix:
- Marks what's already verified (T1 startup wiring, T5 lifecycle,
T6 P0 security via upstream UI, T13 pre-send fix).
- Adds T13 covering the alignment + resolver-probe fix from
a139c0fb17 with three sub-scenarios (strict alignment, resolver
unblock, and the real 2-user bootstrap flow).
- Documents the known pre-existing issues surfaced during testing
(RelayLatencyTracker CME, CompressionQuality stale-daemon) so
they don't get filed as regressions of ours.
- Adds a summary table pointing to the automated sheet for the
Phase A greens.
- Explicit out-of-scope list mirroring the deepening synthesis.
