fix(ida): preserve native coverage and verify returned values (#2324)

Reject native callee successes without an explicit truncation marker while preserving provider failure reasons. Verify positive procedure inventory/search and function-result parity in the real-provider lane; support independent string/xref oracles and label their absence as unverified.

Verified with Windows IDA Pro 9.3: eight normal production CLI/MCP checks passed, and six real-provider response-fault cases reproduced old false positives and validated the correction. Windows IDA Free was not used. No personal paths or license registration information are included.

Repair inconsistent complete-file Ghidra test probe sizes after the shared ELF-header validation change, deriving sizes from the fixture buffers. Reproduced the three failures before the correction; 115 related installation/doctor and ELF tests pass afterward. Runtime parsing and installation behavior are unchanged; no real-Ghidra verification is claimed.

207 focused IDA tests and static/documentation checks passed. Automated review completed on d1e0b1095 without findings. CI run 38327862093 passed all 36 jobs, including Windows, all six test shards, coverage/timing, and real Apple CLI/MCP workflows.

Follow-up to #1544.

 Native verification requires `--second-procedure other_function --second-marker unique_second_body_text`; these options remain optional for the other profiles. The marker must occur in the second function's pseudocode and be absent from the first; the verifier also checks that returning to the first restores its text.
 
+The verifier requires the resolved procedure in both inventory and procedure search, then compares address, assembly, pseudocode, instruction windows and relationship results with the CLI/MCP dossier. Supply `--expected-string known_literal` to check a known positive string inventory/search result and `--expected-xref 0xSOURCE` to check a known reference source address. Choose those oracles independently from the operation under test. Without them, string and xref correctness are listed in `unverified`; valid output shapes alone do not establish those behaviors. Callee parity does not independently establish semantic completeness. Native callee successes must report an explicit truncation marker; missing markers remain protocol failures.

 The initial real workflows use stdio registrations for the legacy Windows GUI profile and a Windows x64 headless supervisor with IDA 9.3. The headless workflow has also passed on macOS arm64 with IDA Professional 9.1 (build 9.1.250226) against the same upstream commit `c133c3853faa111a9b00ee615c013b720d0c4acd`, using a source-built arm64 Mach-O fixture; Mach-O C symbols carry a leading underscore, so the procedure name is `_rea_fixture_add`. Streamable HTTP is tested against a loopback MCP fixture with the pinned client SDK; a real IDA HTTP-supervisor workflow remains unverified. Linux headless engine operation, other IDA releases, architectures, and modern attached GUI tools require their corresponding real workflows before support is claimed.
 
 Native Windows verification uses IDA Pro 9.3 with the public two-function fixture and Windows `whoami.exe`, using upstream `c9d15d98e8a143fc74f6e14037c48f63889b6d6c` with a loopback-listener change. It covers production CLI/MCP parity, distinct-function switching, identity and connection cleanup. See the [correctness and performance measurements](https://github.com/morluto/rea/blob/main/experiments/analysis-efficiency/ida-native-windows.md). This follow-up did not run Windows IDA Free or native macOS.
