* 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.
Follow #973's native ownership: the call-observation schemas move to
src/domain/native/, and the contract now lives in src/contracts/native/.

Add observe_native_calls (CLI: observe-native-calls <path> <input-json>). It
launches the active Mach-O as an owned process under `lldb --batch`, stops at
caller-selected functions or Objective-C methods, records each entry and
auto-continues:
- thread, image, symbol, load and file address;
- raw integer argument registers and optional caller frames;
- for methods, the selector read from _cmd and the receiver's dynamic class,
from LLDB's runtime reader without running target code.
No expression is evaluated and no existing process is attached. The run ends
on exit, max_events or duration_ms; REA then kills the process and confirms
that it is gone. The result also carries exit status, bounded stdout/stderr,
breakpoint resolution with partial coverage for unresolved requests, and
limitations. A target LLDB may not debug fails with a debugger-attach-denied
reason and remediation.
verify:native-calls checks the tool through the CLI and stdio MCP against a
compiled fixture, compares breakpoint addresses with nm, exercises every
outcome, and checks hardened-runtime targets with and without get-task-allow.
