Link human and machine listening accounts

[emeisazam]

What changed

• advertises the Oída 0.10 / gateway 0.6 human-machine memory contract
• preserves attributable human passes while demoting unresolved machine hearing claims
• writes machine listening and human notes as separate linked Akousma records
• makes Oída-created human accounts owned and additively editable in the embedded Akousmata library
• adds the human-listening HTTP, MCP, and UI surfaces without making notes into heard claims
• prevents remote-ear requests from duplicating machine records
• updates dependency pins and release tooling for the released stack

Why

Oída needs to bridge machine listening and human response while keeping evidence source, editability, and provenance distinct across the complete listening stack.

Validation

• 336 tests and 13 subtests passed
• Python lint and compile checks
• dependency audit: no known vulnerabilities, with two documented model-runtime exceptions
• wheel and source distribution metadata checks
• macOS debug/release builds and unsigned package
• isolated stub release smoke on port 18765: all 15 endpoints and 7 capabilities passed
• staged gitleaks scan: no leaks
