Edits prose in AGENTS.md, CONTEXT.md, docs/adr/0002-free-threading-is-compat-only.md to remove AI-writing tells, mostly em dashes used as all-purpose connectors. Each one is now a colon, semicolon, comma, parentheses or a sentence break, depending on how the clauses relate. ADR 0002 states the free-threading scope directly instead of as a "means X; does not mean Y" pair.

Prose only. Code fences, inline code, commands, link targets and tables are unchanged, and no facts or identifiers moved. git diff --word-diff shows the scope.

Gated (fails the build): delete_calls + tuple counters (upd/del/ins) + the producer's insert_calls, exact; select_calls and other_calls within +2; wal_records within a 10% band; fetch_calls within 2x. msg/s, WAL bytes and total calls are informational (timing/FPI noise).
