Hydrate dependencies for Lab workspace offloads

[chubes4]

Summary

• Generalize Lab dependency hydration from agent-task-only execution to all materialized Lab workspace offloads.
• Keep runner-resident commands out of the hydration path and preserve the global --skip-deps-hydration opt-out.
• Add unit coverage proving non-agent materialized workspace jobs run dependency hydration.

Verification

• cargo test hydration_ --lib
• cargo build
• cargo clippy (passes with existing warnings)
• cargo clippy --all-targets --all-features -- -D warnings currently fails on pre-existing repository-wide warnings outside this change.

AI assistance

• AI assistance: Yes
• Tool(s): openai/gpt-5.5 via OpenCode
• Used for: Investigated the Lab offload hydration path, implemented the generic Homeboy core fix, and ran local verification.
