B-META: wire modules + features for B1-B6 (grammar-triangle, contract-ticket, role_keys, markov_bundle)

- Add pub mod trajectory + markov_bundle (B4 D5).
- Gate pub mod ticket_emit behind feature "contract-ticket" (B5 D2).
- Gate pub mod triangle_bridge behind feature "grammar-triangle" (B5 D3).
- Add features:
    contract-ticket  -> dep:lance-graph-contract
    grammar-triangle -> dep:lance-graph-cognitive
- Add optional path deps for both crates.

B1 grammar-landscape doc has ASCII transliterations (Finnish ä->ae,
Cyrillic->latin) per worker note; flagged for follow-up i18n PR.

Contract-side modules (context_chain, role_keys, thinking_styles)
already re-exported from grammar/mod.rs at base commit 22a5a32.
