v0.17.0 — Polish, composition, and reference primitives

Implements Phase 1 of SPEC-079 on the engine + theme side, without yet migrating the plan plugin (that lands in WORK-306). Three layout primitives, two composable runes, the universal chip primitive, the legacy slots + structure shim, and config-load validation.

Phase 1 proof case for SPEC-079. Migrates the plan plugin's entity runes (work, bug, spec, decision, milestone) from the legacy slots + structure config shape to the new metaFields + zones + sections model. Lands together with WORK-305 so v0.18 ships the spec end-to-end.

Phase 2 of SPEC-079. Migrates the storytelling plugin's meta-bearing runes (Character, Realm, Lore, Faction, Plot) from the legacy slots + structure config shape to the new metaFields + zones + contentSlots model. No visual change — Phase 1 already moved the chip look universally via Lumina's dimensions/metadata.css rewrite + the universal .rf-badge class. Phase 2 is purely config-shape cleanup.

Phase 2 of SPEC-079. Migrates the learning plugin's meta-bearing runes (HowTo, Recipe) from the legacy slots + structure config shape to the new metaFields + zones + contentSlots model.

Phase 2 of SPEC-079. Migrates the docs plugin's meta-bearing runes (Api, Symbol) from the legacy slots + structure config shape to the new metaFields + zones + contentSlots model.

Phase 2 of SPEC-079. Migrates the places plugin's meta-bearing rune (Event) from the legacy slots + structure config shape to the new metaFields + zones + contentSlots model.

Phase 2 of SPEC-079. Migrates the media plugin's meta-bearing runes (Track, Audio) from the legacy slots + structure config shape to the new metaFields + zones + contentSlots model.

Phase 2 of SPEC-079. Migrates the core {% budget %} rune (the only core rune using meta-projection — currency, duration meta fields) from the legacy slots + structure config shape to the new metaFields + zones + contentSlots model.

Infrastructure for SPEC-080. Adds blocks and layout to RuneConfig and the engine projection that composes a rune's transform tree with projected metadata blocks, placed explicitly into named containers. Built behind the new fields so the SPEC-079 path (zones / zoneLayouts / contentSlots / order / zoneHost / zoneHostPlacement) and the legacy slots / structure shim keep working untouched during the migration.

The rendering primitives SPEC-080 depends on: a single bar horizontal layout (merging split + chip-row), field shape decided intrinsically from metaType, a new code metaType, and the rename of the unreleased eyebrow rune to bar.

Re-migrate the plan family (work, spec, bug, decision, milestone) from the SPEC-079 metaFields + zones model (WORK-306, done) to the SPEC-080 blocks/layout model. The metaFields manifest is reused as-is; the zones / contentSlots / order / dispatcher reliance is replaced by transforms that build named-block trees plus blocks / layout config. This is the bulk of the SPEC-080 migration — the plan family leans hardest on the engine dispatcher.

Re-migrate recipe + howto from the SPEC-079 zones model (WORK-308 plus this branch's recipe/howto work) to the SPEC-080 blocks/layout model. These runes already build content + media trees and nest the metadata def-list via zoneHost / zoneHostPlacement, so they map almost directly.

Migrate the docs meta-bearing runes (Api, Symbol; Changelog untouched) straight to the SPEC-080 blocks/layout model. api is the deliberate proof point: method/auth render as chips and path renders as a bare <code> — all from metaType, in one flat bar — with no layout-specific or slot-specific logic.Supersedes WORK-309, which migrated docs to SPEC-079 zones (path as metaType: 'id' mono, method/path as split left/right). Skip the now-obsolete zones step and go directly to blocks/layout. api is still on the legacy structure path today, so this is its first real migration.

Once api proves the model (WORK-318), migrate the remaining meta-bearing runes to SPEC-080 blocks/layout: storytelling (re-migrate faction / realm / character + lore / plot / others), marketing, business, places, media, design, and core runes (e.g. budget).Supersedes WORK-310 (places), WORK-311 (media), and WORK-312 (core budget) — those targeted SPEC-079 zones; migrate straight to blocks/layout instead. May be split into per-package sub-items during execution.

Once every rune is on blocks/layout (WORK-319), remove the superseded SPEC-079 placement surface from RuneConfig + engine and finalize the contract. Coordinate with WORK-313 (remove the legacy slots / structure shim) so only blocks/layout plus the projection / postTransform escape hatches remain.
