docs: record #80/#95/#98/#102 regression tests added in 713d426

Updates docs/history/49be664_open_issues.md to reflect that the four
JUnit regression tests called for in the verification plan have been
added on this branch:

- Deep-dive verdict guide now lists each test name and self-skip
  behaviour next to its issue bullet
- Per-issue Status blocks for #80, #95, #98, #102 annotated as
  "LIKELY FIXED -> FIXED on CI green" with the covering test
- Status overview table rows for the same four issues updated
- "What the original issues actually contain" feasibility table marks
  all four as DONE with the commit reference
- "Concrete test plan" gains a status callout noting the as-shipped
  implementation matches the sketches
- "Recommended sequencing" step 1 marked DONE and enumerates what
  shipped; remaining steps (#86 docs, #103/#34 typed image API, Android
  emulator CI) carried forward as the next deliverables

No code or behaviour change, documentation only.
