docs(wiki): add blog post roadmap

[Decipher]

Adds the actual roadmap file — recovered from the same OpenCode session as wiki/syndication-strategy.md, but previously only landed in Claude's memory system, not the repo. Doc-only. Mirrors gitlab.local MR !45.

[Decipher]

Closing — this content shouldn't be on the public mirror. Kept private on gitlab.local (MR !45).
