feat(fiction-assistance): register plugin with full bespoke command set

Snapshot of the fiction-assistance plugin in its original Universalis-
specific form before generalization. Adds the missing plugin.json
manifest (subdirectory command paths explicitly listed), moves the two
stray root-level review files into their proper homes (review-all.md
into the reviewing-fiction skill, review-final.md as a command with
frontmatter), and registers the plugin in the marketplace.

Preserved here so the original card-generation and vault-maintenance
commands remain recoverable when the plugin is reduced to a portable
guidance-and-analysis subset in the next commit.

+description: Update ship cards
+allowed-tools: Edit(40 - Generated/**), MultiEdit(40 - Generated/**), Write(40 - Generated/**)
+---
+You are analyzing scenes from a science fiction novel to create ship cards.
+
+Scan the files in the `00 - Manuscript/` directory and identify all story vessels (ships, shuttles, fighters, stations, etc.).
+
+With EACH ship found:
+
+Update (or create, if needed) the ship card in `40 - Generated/Ships/{ship_name}.md` for use in Obsidian.
+
+Use wiki-style links (`[[file.md]]` or `[[file.md|display name]]`) when referencing manuscript chapters or other files in `40 - Generated/` such as characters, locations, species, etc.  This applies in the frontmatter and in the Markdown below it.
+
+Extract factual information ONLY from the scenes. Do not invent or infer details not explicitly stated in the text.
+
+ALWAYS update the card to match the current format.
+
+Use the following structure:
+
+```yaml
+---
+type: ship
+name: [full name]
+aliases: [list, of, ship, aliases]
+tags: [ship, generated]
+ship_type: [cruiser/fighter/shuttle/station/transport]
+origin: [human/alien/unknown]
+status: [active/destroyed/missing/decommissioned]
+appearances: [list, of, chapter, filenames]
+crew: [list, of, key, crew, members]
+captain: [current, captain, name]
+technology: [list, of, key, technologies, onboard]
+created: {{first_date}}
+modified: {{current_date}}
