docs(B.5): ship handoff + roadmap/CLAUDE update + file #63 #64

Phase B.5 (ground-item pickup, close-range path) shipped and
visual-verified 2026-05-14 at Holtburg. M1 demo target 4/4 ("pick up
an item") met.

New ship-handoff doc captures the 5-commit history including the
post-visual-test PickupEvent (0xF74A) wire-handler fix that closes
the local-despawn gap.

Roadmap and CLAUDE.md updated to reflect the ship + the new follow-up
issues:

  - #63 (MEDIUM) — server-initiated MoveToObject auto-walk not
    honored; blocks double-click pickup + out-of-range F. Filed as
    candidate Phase B.6. holtburger has the reference implementation.
  - #64 (LOW) — local-player pickup animation does not render
    (retail observers see it correctly). Likely a self-echo filter
    dropping UpdateMotion(Pickup) on the local player.

Carry-overs from B.4c (#61 link-cycle flash, #62 PARTSDIAG null-guard)
unchanged.
