Adds Serialize/Deserialize to SelectedBookmark and wires it into
SaveStateV1 so a loaded game remembers which bookmark and starting
location the player picked. Replaces the TODO at bookmark/mod.rs:95
(originally deferred to Sprint 37 alongside #614).
Also refactors BookmarkPlugin to accept an injected BookmarkRegistry
via BookmarkPlugin::new(registry) (#862). The Default constructor
still wires the canonical tycoon registry — injection is for tests
and future TOML loading. Flagged in PR #132 review as a follow-up.
Updates bookmark spec §4.4 to remove the v0.2-deferred scope note.

Per R-012: delete conversation.rs, both overheard content files, and
remove all 6 wire-up points (social_plugin, bridge/types, monologue,
voice/integration). Protocol version 22 → 23. Scope confirmed by
#842 audit — npc/ and content/global/ untouched. Surviving NPC
components (NpcName, NpcColorIndex, NpcConversation) migrated to
simulation/npc_components.rs for use by D-080 knowledge propagation.
Also applies pre-existing cargo fmt debt (names.rs and 4 others).
