* 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.

* 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.
Collect references from the complete owned function body and exact entry,
including instruction-interior destinations and embedded-data sources.
Bind the corrected semantics to the analysis profile so legacy snapshots
cannot replay incomplete results. Preserve snapshot mismatch reasons and
recovery advice through CLI and MCP without disturbing live sessions.
Return exact entry candidates for ambiguous function names. Expand the
real-provider regression workflow and replace redundant parser assertions
with malformed-output coverage through the pinned MCP client.
Verified with Ghidra 12.1.4 on macOS arm64: full host-native lane, real
CLI/MCP boundary probes, 30 focused tests, and typecheck/lint.
