plan: batch-200 expansion (100 Pro + 100 Std)

Doubles down on what worked in batch-50:
  - dev1 (Guangzhou) is primary execution host
  - Owner cap=2 for diversity
  - --max-source-mb 200 to defend against X86-class outliers
  - Pro 2.x deprecated-board fix is already in (commit c3cac97)
  - SSH transport for dev1 -> gitea (commit 8220c99)

Candidate pool:
  200 picks from A-tier (grade>=3 & like>=10) minus already-crawled 65
  Remaining A-tier corpus is 2,741 (Pro 1326 + Std 1415)
  173 unique authors, like median 258, grade dist 4:118 / 3:82

Estimated walltime ~25-35 min on dev1 for Step 1-4 (no attachments).
LFS increment ~2.5 GB (source only) or +10 GB if Step 5 attachments
included. Either way well within Gitea's 200 GB migration threshold.

Step 5 (attachment download) deferred — not on the critical path for
EPRO2/Std → KiCad work, can revisit when license-filtered Forge
projection demands it.
