/**
* Section resolvers (v2 plan T9, Claude-first carve).
*
* A carved skill keeps its prose-heavy steps in `<skill>/sections/<id>.md`, read
* on demand. The SAME template ships to every host, so these resolvers make the
* carve host-aware:
*
* - On CLAUDE: {{SECTION:id}} emits a STOP-Read pointer to the generated section
* file (the skeleton), and the section .md is generated + installed separately.
* - On every OTHER host: {{SECTION:id}} INLINES the section template's content,
* so external hosts keep the full monolith ship skill (no section files, no
* host-portable-path problem). Inlined content keeps its own {{RESOLVER}}
* tokens, which the generator's multi-pass resolve expands.
*
* {{SECTION_INDEX:skill}} renders the situation→section table from the PASSIVE
* manifest on Claude (empty on other hosts — they have no sections). The manifest
* is the single source of id/file/title/trigger text (CM2; v2_PLAN.md:663).
