feat(#762): persona batch 3 — the campus workforce, a coach, an alum, a visiting scholar

[0frankie]

Round 3 of the persona library (#762): 6 new catalog-only personas, 35 → 41. The roles the issue body called out (librarian, dining, facilities, athlete, postdoc, prospective student, admin) were all covered by rounds 1–2 (leon, rosa, gus, imani/dana, nadia, casey, debra), so this round fills the remaining campus-workforce gap around the mostly-student cast, plus two visitor types the library didn't have.

The six

id	who	shape
benny	Benny Tran, 52 — coffee-cart vendor, eighteen years on the walks	early riser; barely leaves the outdoor hub (one Houston Hall restock run)
terrence	Terrence Boyd, 45 — Penn public-safety officer	overnight shift's end; patrols all six buildings before turning in the radio
angela	Angela Rooks, 49 — track & field sprints coach	the athletics staff side of the existing athletes
evelyn	Evelyn Marsh, 47 — Class of 2001, back for her 25th reunion	nostalgia criss-cross (College Hall → union → her old thesis carrel → the green → Irvine)
amara	Amara Diallo, 38 — visiting astrophysicist from Dakar	jet-lagged morning timed to reach Irvine before the 10:00 gravitational-wave lecture
vera	Vera Kovacs, 33 — Irvine Auditorium AV technician	one-building day (never leaves Irvine); stranger at t=0 (#582)

Thread structure

Two new-pair threads with proximity-honest scripted meetings, plus three cross-links into earlier rounds (each fires only when both ends are cast):

• benny ↔ terrence — vendor & regular (closeness 3): adjacent spawn tiles on the green, and the end-of-shift espresso meeting fits inside Terrence's 60-step first stop.
• evelyn ↔ angela — coach & former athlete (closeness 3): reunion catch-up at Houston Hall, inside Angela's 240-step union stop.
• terrence → gus (security/facilities colleagues), angela → imani (coach & sprinter), amara → tanaka (research collaborators, with a pre-lecture meeting inside Tanaka's 800-step Irvine stop).

Contract notes

• Catalog only: the default cast, its three persona files, and the world YAML are untouched — the baked replay stays byte-identical (Replay bake: the byte-identical acceptance (#613/#622) has no mechanical guard, and the canonical bake is ambiguous #640; test_replay_contract green).
• All activities pre-flighted through the real parser (perform <activity> → perform): no banned verb substrings, no out-of-window time words, and — learned the hard way — no commas, which the parser reads as a command-sequence separator.
• Vera's "the 10:00 guest lecture" wording follows the one sanctioned clock-time exception (anchoring the world YAML's shared event, same as tanaka.yaml), and her sound-check stop runs ~09:00–09:40, before the time it names.
• Start tiles probed against the built world map: walkable, outside every building arena, no collision with the other 35.
• Pins updated: test_config_api_732 id set (+6), the library floor in test_persona_library_762 (≥ 41), README catalog table.

Tests: godot-generative-agents/tests/ full sweep — 971 passed.
