Plan Icod.TermInfo 1.16.0 Hash-v9 writer

[uniblab]

Summary

• records the approved 1.16.0 writer-only scope in the authoritative post-1.0 roadmap
• adds the full HW00–HW08 development roadmap for deterministic pure-managed Berkeley DB Hash-v9 publication
• keeps Icod.TermInfo.BerkeleyDb Runtime-only and composes hashed publication in tic
• explicitly defers directory/hashed migration, unified catalog automation, cross-container planning, and JSON v7 to 1.17.0
• links the active roadmap from the repository README

1.16 north star

compiled terminfo bytes
    -> deterministic Hash-v9 image
    -> verified whole-file publication
    -> explicit tic hashed output

Verification

• committed-tree whitespace and placeholder checks passed
• exact three-file scope verified
• all nine HW00–HW08 gates verified present
• historical 1.15 coordinated-version, completed-line, and release-audit markers preserved
• remote comparison is one commit ahead of main, zero commits behind
• local .NET execution was unavailable because this workspace does not contain the dotnet command; GitHub Actions remains the build/test gate

Next gate

HW00: native interoperability and writer-backend proof. No 1.16 production behavior or public API is implemented by this planning PR.
