relayburn-sdk: split verbs into their own modules

[willwashburn]

Summary

Pre-declares three empty module files (query_verbs.rs, ingest_verb.rs, export_verbs.rs) and wires them through lib.rs. The verbs themselves are filled in by three parallel follow-up PRs; this PR exists so each of those touches only its own file and they don't fight over lib.rs.

Part of #246.

Test plan

• `cargo build -p relayburn-sdk` clean
• `cargo doc --no-deps -p relayburn-sdk` clean

📝 Walkthrough

Walkthrough

Three new verb modules—export_verbs, ingest_verb, and query_verbs—are added to relayburn-sdk as documented placeholders. Each module file contains descriptive documentation and TODOs for future implementation. Module declarations and public re-exports are wired into lib.rs.

Changes

Verb Module Scaffolding

Layer / File(s)	Summary
Module Documentation crates/relayburn-sdk/src/export_verbs.rs, crates/relayburn-sdk/src/ingest_verb.rs, crates/relayburn-sdk/src/query_verbs.rs	Three new modules defined with module-level documentation describing intended verbs (export, search, ingest, summary, session_cost, overhead, hotspots) and implementation plans. Each includes a TODO to port from JavaScript sources.
Module Integration crates/relayburn-sdk/src/lib.rs	Private module declarations added for export_verbs, ingest_verb, and query_verbs with explanatory comments. Public re-exports via pub use make all module contents accessible from the SDK root.
