Adds the highest-leverage reverse-engineering primitive from the roadmap: one path to turn a live operation buffer into a committable golden fixture. Unblocks every capture-tier item (R0.5, R1.x, R2.1). - ProtocolCaptureSanitizer: redacts identity-bearing values (host, tag, user, machine) from a native buffer in BOTH ASCII and UTF-16LE, overwriting in place with an 'X' fill so length and every field offset are preserved (keeps the fixture useful for byte-layout RE). ASCII-letter matching is case-insensitive; secrets < 3 chars are skipped to avoid collision corruption. AssertNoSecretsRemain is a fail-closed safety net that refuses to emit if any value survives. - ProtocolFixtureWriter: serializes a capture to fixtures/protocol/<op>/<name>.json with sanitized hex, length, SHA-256 of the sanitized bytes, and a scrub report. Timestamps are passed in (deterministic / testable). - capture-tag-info CLI command: captures a live GetTagInfoFromName response and writes the fixture. The same native bytes ride inside 2023 R2 gRPC GetTagInfosFromName, so the fixture is transport-agnostic. - 11 unit tests for the sanitizer/writer (test project now references the RE tool). - First real fixture: get-tag-info/analog-*.json — a 98-byte Int4 CTagMetadata buffer captured live from the local Historian 2020 server, tag name redacted, verified to contain no identity (descriptor 03 c3 00 31 = Int4, as documented). 180 non-live unit tests green.
