Colonist Errands 2.2.0 — the astronomer and the photographer join the conversation

Voyager 0.3 adds two professions - the astronomer at the Observatory and the photographer at the Photo Booth - and until now Talking Colonists knew them only as "a colonist with a job it had never heard of". They now know their work as well as a Voyager knows the End.

• Astronomer truth. The astronomer's prompt says what the job is (nights at the telescope, asleep by day, living at the Observatory, the lookout with a guard escort, the darkroom, the colony's sky book that first sightings pay into), what the Observatory is (its look, level and lens, how many nights have been kept, what is in the book and what came in last, tonight's sky event) and what they are doing right now ("keeping the watch from the lookout under the open sky, camera in hand; caught the Crab Nebula tonight - a first for the colony").
• Photographer truth. The same for the photographer: the studio, the bench work (cameras, film, frames, albums), portraits of colonists, paying visitors, the colony chronicle, prices and sales so far, and the moment ("camera up in the studio, photographing Anna").
• Colony news. Everybody else hears one sentence about the Observatory (who keeps the watch, the latest entry in the sky book) and one about the Photo Booth, alongside the Voyager news.
• Both jobs are CHATTY for citizen-to-citizen chats: the astronomer is idle all day and the studio is a social place.
• /errands reloadtalking (operators). Talking Colonists reads config/yacl-mc_talking.json5 once, at startup, so a changed Gemini API key used to mean a server restart. This re-reads the file in place: conversations started after it use the new key, ones already running keep their connection. It reports whether a key is set and whether it changed - never the key itself - and leaves the old settings in effect if the file does not parse.
• Everything comes from Voyager itself (its status lines and describeForChat(), read by reflection, Voyager 0.3.0-alpha.20 or newer); with an older Voyager the two are simply colonists with a job, as before, and without Voyager nothing changes.
