v0.7.0

New built-in integration: the Pi coding agent. pi auto-discovers an extension Regesto
links into ~/.pi/agent/extensions/, and that extension injects the knowledge-base index
and the facts scoped to the working directory as a persistent message on the first prompt
of every session — the same deterministic consultation Claude Code gets, with no settings
file edited. The integration also links the portable skills into ~/.pi/agent/skills and
creates ~/.pi/agent/AGENTS.md with the marked knowledge-base section. pi keeps no
markdown memory, so harvesting is unchanged. On machines where the shared
~/.agents/skills already carries Regesto skills, override skills_dir for pi so it does
not load two copies of the same names.

New built-in integration: OpenCode. OpenCode auto-discovers a plugin Regesto links
into ~/.config/opencode/plugins/, and that plugin injects the knowledge-base index and
the facts scoped to the current repository on the first message of every session — the
same deterministic consultation Claude Code gets, with no settings file edited. The
integration also links the portable skills into ~/.config/opencode/skills and creates
~/.config/opencode/AGENTS.md with the marked knowledge-base section. OpenCode keeps no
markdown memory, so harvesting is unchanged. On machines that also run the Claude
integration, set OPENCODE_DISABLE_CLAUDE_CODE_SKILLS=1 so OpenCode does not load the
duplicate Claude-variant skills from ~/.claude/skills.
