Group repeated session tool availability and provider capability facts, preserve complete named contracts and ordered limitations, and remove duplicate catalog descriptors. Update consumers and migration guidance.
Validated by all 31 CI jobs, focused source checks, and actual Claude Code/Linux Hopper/native Windows Ghidra small-target workflows on the current integration tree.
Refs #723.
BREAKING CHANGE: binary_session no longer includes server_identity.catalog.tools; tool_availability and provider capabilities use grouped facts documented in docs/mcp-contracts.md.

* fix(mcp): deliver tool errors within advertised schema contracts
Retain complete typed JSON error content while omitting non-conforming
structured errors at the public transport boundary. Recover oversized
diagnostics into Evidence before removing their private structured carrier.
Update schema-validated client readers and cover actual stdio delivery.
Closes#1261

* test(mcp): read typed errors in canonical Evidence regressions
* test(mcp): validate public error diagnostics in acceptance workflows
Deliver complete Evidence directly through MCP with required nullable analysis profiles and immutable per-server delivery settings. Bind selected environments at construction and require typed cleanup outcomes with retained retry ownership.
Remove test-only routing, duplicate session and snapshot metadata, producer-field repairs, and ambiguous provider arguments. Separate artifact byte identity from occurrence classification and retain typed source-map and partial native facts across CLI, MCP, and verifier consumers.
BREAKING CHANGE: obsolete Evidence envelopes, session aliases, incomplete snapshots, and missing normalized producer facts are no longer accepted.
