docs(6204): shipped instruction text describes the product, not this instance's records

MCP tool docstrings and comments, the server's orientation notes, the plugin skills, every hook script and the plugin README/PACKAGING drop record ids, milestone numbers, dates and incident stories, and state each non-obvious why as a present-tense fact. History stays in the task logs. Corrections found on the way: - plugin README/PACKAGING said every hook is a GET; moment, rule-opened and reply-rules POST, so the plugin's key needs write scope. Both now say so, name Settings -> MCP Access, and list every wired hook and endpoint. - the contract-change hint printed "(lesson #4207)", this instance's record, to every install. It no longer cites a record. - tasks.py claimed there is no delete_task; there is. - rulebooks.py cited delete_event and a design spec that no longer exist. - scribe_after_write.sh carried an always-empty etag_q; removed. - test_write_path_trigger pinned "| tac | scribe_defs | head -1", text that existed only in a comment about the old code; it now pins the real tail -1 pipeline. - docs/development.md: CI runs on Gitea Actions.
