* feat(plugins): align opencode and pi memory integrations
* fix(installer): tolerate missing optional harness CLIs
* fix(installer): install opencode file wrapper
* fix(opencode): import path for logger initialization
* fix(installer): register pi extension after copy
* feat(plugins): use MCP for opencode integration
* docs: move OpenCode and pi integrations to dedicated pages
Promote the OpenCode plugin and pi extension out of the community-plugins
page into their own numbered agent-integrations pages (10-opencode, 11-pi,
en + zh), update the overview routing table, and refresh the OpenCode image
cards to the hybrid MCP architecture (unified installer, openviking_* MCP
tools, ovcli.conf credentials).
* docs: bare TOS installer commands and reference more examples
Drop --harness from TOS-mirror install commands (image cards use the bare
installer URL, matching the claude-code/codex cards); add Open WebUI tool
server and an examples/ pointer to the community-plugins page (en + zh).
* docs: bare TOS installer commands across agent-integration pages
TOS-mirror install commands carry no flags anywhere; the installer wizard
asks for source, harnesses, language, and credentials.
