Big upgrade in programming languages supported by adopting tree-sitter-language-pack. 130 new languages with linter support. 20 new languages with repo-map support. Added `/think-tokens` command to set thinking token budget with support for human-readable formats (8k, 10.5k, 0.5M). Added `/reasoning-effort` command to control model reasoning level. The `/think-tokens` and `/reasoning-effort` commands display current settings when called without arguments. Display of thinking token budget and reasoning effort in model information. Changed `--thinking-tokens` argument to accept string values with human-readable formats.

Added `--auto-accept-architect` flag (default: true) to automatically accept changes from architect coder format without confirmation. Added support for `cohere_chat/command-a-03-2025` and `gemini/gemma-3-27b-it` The bare `/drop` command now preserves original read-only files provided via args.read. Fixed a bug where default model would be set by deprecated `--shortcut` switches even when already specified in the command line. Improved AutoCompleter to require 3 characters for autocompletion to reduce noise. Fixed handling of JSONDecodeError when loading model cache…
