- Migrated the `pi` AI dialect from legacy XML-style elements to a compact, token-frugal sigil-delimited format using `§` for calls, `""` for body fences, and `¤` for thinking. - Implemented robust parsing for the new format, including support for incremental streaming of tool arguments and automatic escalation of body fences to prevent content collisions. - Updated documentation, settings configurations, and test suites across the `ai` and `coding-agent` packages to ensure consistency with the new dialect rules. - Standardized moderation category terminology in `stats` to improve clarity in reporting metrics.
