Column-staggered right half, and record the ragged-edge decision

Browse Source 
Six clean finger columns then an outer pinky edge carrying Bksp, ] and Enter,
with backslash alone in an eighth column. Documents why the artifact exists -
the number row and alpha rows are cut half a unit apart - and the three ways
to resolve it. Also flags the right thumb being asked to cover five keys.

mod and reclaiming that slot for a layer key.
The right is worse: **five** thumb keys (Space / Alt / Win / Menu / Ctrl). One
thumb will not cover five. Menu is the obvious deletion — nothing else on the
board is used less.

### The ragged outer edge — an open decision
Splitting a row-staggered 104 leaves keys that have no column to belong to,
because the number row and the alpha rows are cut half a unit apart.
- **Left half:** `6` and `F6` end up alone in a 2-key column. `6` sits at x=6.0,
`T` at x=5.5, `Y` at x=6.5 — so `6` is *between* T and Y, and falls left of
the cut with no alpha beneath it.
- **Right half:** worse. Six clean columns, then an outer pinky column holding
Bksp / `]` / Enter, and **`\` alone in an eighth column**.
Three ways to resolve it, undecided:
1. **Keep it.** Authentic to touch-typing — `6` really is a left-index stretch.
2. **Move `6`/`F6` right**, aligned above `Y`. Left becomes a clean 6 columns at
34 keys, right goes to 41.
3. **Duplicate `6` on both halves.** What the ErgoDox does. Costs one key, ends
the argument.
`\` has no equivalent escape — it either gets its own outer column, moves onto
a layer, or takes a thumb slot.
