Support raw view output in replay fixtures

[erik-krogh]

Summary

Companion to github/copilot-agent-runtime#13802 and github/copilot-agent-runtime#10996.

• canonicalize shared view tool snapshots to raw file content
• preserve compatibility with currently published CLIs by trying exact replay matches first, then a narrowly scoped legacy sequential-line-prefix fallback for view results
• cover naturally numbered raw files, ranges, CRLF, non-view tools, non-sequential output, and cross-snapshot-type match priority

Testing

• cd test/harness && npm test -- replayingCapiProxy.test.ts (34 passed)
• cd test/harness && npx tsc --noEmit
• git diff --check

The fallback can be removed once the minimum supported CLI version always emits raw view output.

Fixed in cca1c28: the fallback now deletes the candidate content field when legacy numbering strips to empty, matching canonical normalized messages. Added an end-to-end empty-file replay test; harness tests and typecheck pass.
