Implement Depone V107 Agent Fabric contracts

[moonweave]

Summary

• Renames active public/product surfaces from Keelplane to Depone without changing historical filenames that remain contract evidence.
• Implements the V107 Agent Fabric contract/compiler slice: role/toolbelt/harness/profile schemas, compile reports, invocation/result validation, tool mapping, and compile_agent_fabric(...).
• Exposes active CLI paths for the new slice: depone compile --target agent-fabric, depone validate-contracts --self-test, and depone validate-contracts --all.
• Updates release/roadmap/decision docs and regenerated contract fixtures so repo-level gates align with Depone branding.

Safety boundary

• No live model execution is added.
• No hard per-agent tool-filtering claim is made for harnesses that only approximate it.
• Agent result self-reports remain non-authoritative and are blocked from claiming observer-owned evidence paths.
• Repo slug / historical keelplane evidence filenames remain migration debt where contractually historical.

Review fixes included

• Routes kind: agent-fabric-contract payloads to the combined cross-contract validator before role-set fallback.
• Adds profile-set dispatch support.
• Blocks undeclared MCP allocation and observer-owned evidence outputs.
• Exposes Agent Fabric compile target via CLI.
• Makes validate-contracts --all validate shipped harness capability fixtures.

Verification

• python3 scripts/check_contract.py → contract full: pass
• python3 scripts/check_contract.py --tier changed → contract changed: pass
• python3 -m depone compile --self-test → conductor 4/4, agent_fabric 6/6
• python3 -m depone validate-contracts --self-test → 20/20
• python3 -m depone validate-contracts --all → all shipped capability fixtures valid
• python3 -m depone design --self-test → 4/4
• python3 -m depone demo --self-test → pass
• changed Python files py_compile → pass
• active public stale-brand grep → pass
• python3 scripts/dwm.py next --run out/v9/v32-semantic-dogfood --json → workflow-complete
