Locks the body<->refs coupling: gemini ships claude's lean skill.md body but
resolves references through a separate path, so a real install with the real
claude bundle must leave every references/ pointer in SKILL.md resolvable.

gemini has no _PLATFORM_CONFIG entry and installs claude's skill.md body
verbatim. Since #1121 that body is the lean progressive core that links to
references/, but _packaged_skill_refs_dir returned None for gemini, so the
install laid down a SKILL.md with 8 dead reference pointers. Resolve gemini
to the claude references bundle (the same body it already ships) and guard
it in test_claude_twins_ride_the_claude_bundle.

Same 3.11+-stdlib issue as gen.py: this test imported tomllib directly, failing
the 3.10 job. Fall back to tomli on <3.11.

All-platform progressive-disclosure skill split + generator (addresses #1106).
Splits each platform's skill into a lean core (~615 lines, full default pipeline inline) + on-demand references/, generated from a single source via tools/skillgen with a CI/pre-commit drift gate. 13 hosts split, aider/devin stay monoliths. Also fixes the stale bare-path bugs across the previously hand-maintained variants and moves the always-on blocks into packaged markdown.
Verified: all 5 generator guards pass, byte-verbatim load-bearing slices, lean cores self-sufficient on the default path across all 13 split hosts, references gated to non-default branches, description preserves the graphify-out-query-first clause. Supersedes #1119 (Claude-first subset).
Known follow-up applied on top: harden _always_on() against a missing packaged file so a partial install can't brick the CLI.
