* refactor(domain): consolidate canonical ordering and digest helpers
Single owner for code-point ordering (domain/canonicalOrdering.ts)
and canonical JSON digests (domain/comparisonSemantics.ts). Delete
all local compareCodePoints/compareText/digestCanonical duplicates
and migrate every importer. No re-export shims.
* fix(ci): allow slower real browser startup
Validate DOS MZ load modules and import them with Ghidra's 16-bit
real-mode profile. Preserve complete observed inclusive function body
ranges through inventory, function analysis, Evidence and snapshots.
Add a public source-generated DOS CLI/MCP verification lane and
regressions for malformed headers, body membership and cache profiles.
