飞控-77: 74 std flight-controller projects ingested

Topic-pull from local listing index (`name OR introduction` contains
飞控). 77 std hits in oshwhub_listing_full.jsonl, minus 2 already
crawled = 75 attempted; 74 OK + 1 hard fail (`m1_mh743_ada_v4`,
listing entry missing `count.like`).

dev1 walltime: Step 1 ~12s, Step 4 ~80s (concurrency=5).
License mix: 65% GPL 3.0, 11% Public Domain, 11% MIT, 4% CC variants.

3 partial dirs (Step 1 KeyError on missing `count.like`) dropped — to
be re-fetched after a follow-up crawler patch makes count fields
defensive against listing-index outliers.

Source backfill 74/74 OK, total +46 MB.
