docs: refresh PROJECTS.md phase 2/3 to match what shipped

* Phase 2: strings has the F2 toggle now, so drop the "still needs it" note.
  Record the 60-row project cap and the reason for it, and the ranking rule —
  including why the (binary, addr) tiebreak is load-bearing (a name shared by two
  binaries ties on every other field and Python then compares hit objects,
  raising TypeError; that shipped as a crash and was fixed).
* Phase 3: spell out precisely how it relates to the PLT/import-stub backlog
  item. An export index turns "follow strcmp -> extrn strcmp:near, dead end" into
  a real jump into libc WHEN that library is in the project. It doesn't retire
  the item: a single-binary session, or a provider outside the project, still
  lands on a stub and still wants it recognised and presented as an import rather
  than a decompiler error.
