Subject: [PATCH] feat(seed): replace synthetic Okafor seed with the REAL
 McClean Lab (public data)

Swaps the prototype's single seed lab from the synthetic "Okafor Lab" to the
real McClean Lab (PI Megan N. McClean, Dept. of Biomedical Engineering,
UW-Madison), populated only from cited public evidence. All four flows + the
guided tour now render coherently with McClean data and real citations.

INTEGRITY BOUNDARY (documented at the top of src/lib/data.ts):

REAL (from public sources, never invented):
- LAB identity, mission, dept, Room 3156 ECB  [mccleanlab.bme.wisc.edu]
- PEOPLE names/roles/emails (emails left "" where not public)
  [mccleanlab.bme.wisc.edu/people/people/]
- SKILLS, EQUIPMENT + models (Nikon Eclipse Ti, Eppendorf 5810R/5418)
  [openwetware.org/wiki/McClean:_Nikon_TI_Basic_Use]
- REAGENTS + catalog numbers (PEG Sigma P3640, carrier DNA Sigma D1626,
  glass beads Fisher 11-312B, filter Nalgene 295-4545)
  [openwetware.org/wiki/McClean:Yeast_Transformation]
- PROTOCOLS + steps + why + hazards (yeast transformation, Nikon Ti startup)
- TACIT_NOTES verbatim (PEG-through-filter, carrier-DNA boil, scope warm-up,
  mandatory log book)
- ONBOARDING journey (Statement of Expectations, WisCard, Ashley Prochaska HR,
  Larry Wheeler keys, OWW/CAE/Quartzy, biosafety training)
  [openwetware.org/wiki/McClean:_Joining_The_Lab]

DEMO (synthesized, marked illustrative; captured at onboarding in production):
- skills-competency MATRIX cell states
- per-person joined dates, isNewHire / leavingInDays flags
- the literal sole-ownership claim

Bus-factor-1 thread is grounded in REAL named-author protocol attribution
[openwetware.org/wiki/McClean:Protocols]: Ping Xu owns the "P. Xu" FISH variant
(departing-expert thread), Renee Szakaly owns the "Mix & Go" competent-cell prep.
The departing/new-hire TIMING is marked demo. New hire = Timothy Wakiyama (real
roster member). Capturing Ping's FISH know-how drops bus-factor-1 risks 2 -> 1.

CI: typecheck + next build green. Zero em-dashes. JoVE branding and
DESIGN-SYSTEM intact. README data-provenance note updated.
