Adventure Arena: tappable prose links, no chapters, optional drop caps, no compass

[corepunch]

Depends on corepunch/zilscript#82 — this branch pins the zilscript submodule to that PR's commit (0161b78). Merge it first, then re-pin to the merge commit if it is squashed.

What changes

#	Request	Result
1	Prose gives away what must be examined	Sanitarium's drawing, cabinet, serum label and ledger are revealed by examining them (zilscript PR)
2	go back / walk back	Works in every story, from the bootstrap (zilscript PR)
3	Drop "Chapter"	Rooms are scenes named for the room; no numbering in the page, running head, Library, accessory or saves
4	Optional drop cap	Drop Caps toggle in Themes & Settings, persisted, default on
5	Remove the compass	Off the reader's page; the command field fills the bar. Compass.etlua and CompassGesture are kept and still tested
6	Tappable words	Links authored in the story's prose, ruled with a dashed underline, open a native menu of actions

Framework: <Hyperlink> in <Paragraph>

<Paragraph text="A corroded brass plaque hangs askew on the gate.">
  <Hyperlink location="11" length="12" label="plaque">
    <MenuItem title="Examine plaque" action="examinePlaque" />
  </Hyperlink>
</Paragraph>

• UIKit: a tagged text item (UITextItemTagAttributeName); the text view presents the menu itself on tap.
• AppKit: an NSLinkAttributeName run; a click pops up an NSMenu under the words.
• Links follow the typewriter reveal, skip a dropped initial, and are replaced in place by a retained template (updateRecords).
• Shared link model and bridge: src/shared/paragraph_links.m.

App

• Session.parseLinks strips [[label->target]] markup into per-paragraph links; Session:linkActions offers "examine" plus the story's verbs for the object (those needing no second object), or the walk for a direction.
• Links are live only in the scene the reader stands in; the words of rooms left behind are plain prose.

Verification

• make test: 197 test files pass (2 new: paragraph_links, adventure_arena_links).
• iPhone 17 simulator: opened Sanitarium, tapped "brass plaque", chose Read plaque from the menu; checked Paper and Night, drop caps on and off.
• Not checked visually: the AppKit menu popup on macOS (covered headlessly only), and iPad.

Notes

• Saves made before this change replay their commands against the new prose, so a Sanitarium save that took the scalpel without examining the cabinet will replay differently.
• Only Sanitarium's opening rooms carry links so far.
