Problem

gog slides can insert/replace text but has no text-formatting commands — all sub-range styling, hyperlinks, and bullet toggles require dropping to the raw Slides API (updateTextStyle, createParagraphBullets, deleteParagraphBullets).

Separately, replace-text:

• cannot be scoped to a single element (only --page <slideId> or whole deck), and
• spans the entire deck by default — an unscoped replace-text silently changes matching text on every slide. This is a footgun for surgical work.

Repro

# leaks across all slides:
gog slides replace-text <deck> "Foo" "Bar"          # changes Foo on every slide
gog slides replace-text <deck> "Foo" "Bar" --page <slideId>   # tightest gog can scope; still whole-slide
# no way to: bold one word, color a phrase, add a link, toggle bullets

Suggested

• gog slides style-text <deck> <objId> --range a:b --bold --italic --color #RRGGBB --size N --font NAME
• gog slides bullets <deck> <objId> --on|--off [--preset ...]
• gog slides link <deck> <objId> --range a:b --url ...
• replace-text: add --object <objId> for element scope, and consider requiring --page/a confirmation when unscoped.
