erga 0.29.0 — seamless block edges

Download erga-0.29.0-arm64.dmg, drag to Applications, then:

xattr -dr com.apple.quarantine /Applications/erga.app

Added

• Seamless block edges. The next block's table is built while the current
  one mines, in the compute the memory-bound scans cannot use (the V7
  diagnostic measured ALU running 10× spare). At the edge the tables swap and
  mining continues. Verified live at height 1863302→1863303: 39.4 MH/s · next table ready → 39.6 MH/s on the new height, next line of the log —
  no pause, and the following block's build already started.

  The price is a second table in memory while both exist, so the machine
  decides fresh at every block, against what is available right now: max
  wants the table plus 3 GB spare, eco plus 8 GB, min never prefetches. On
  a 16 GB Mac nothing changes at all. A block arriving before the build
  finishes flips it to urgent — the familiar pulsing battery, minus whatever
  was already done.

  The regime is visible everywhere: a calm battery in the header (no pulse —
  nothing is waiting) with next table N%, the same in erg mine, and a
  next table row in THE MACHINE that reads ready when the next edge will
  cost nothing.

Changed

• The version caps read v0.29.0 · mit. The window deliberately does not
  volunteer everything — the development share among it — and the licence is
  the honest pointer: every answer is in the code, and the code is yours.

Removed

• The to development row. The count still exists in the store and the log;
  the interface does not advertise it.

Zero clippy findings; 21 tests.
