Backpack Emacs v0.4.0

This release introduces the self-documenting inventory browser, a major new feature that makes Backpack fully self-documenting. It also adds support for 8 new programming languages and file formats, a refreshed README, and numerous quality-of-life improvements.

Highlights

Self-Documenting Inventory Browser (M-x backpack-inventory)

Backpack is now self-documenting. Press C-h B or run M-x backpack-inventory to browse all available pouches, gears and flags interactively. The inventory:

• Discovers pouches and gears automatically from the filesystem
• Parses gear source files on demand using Emacs's read function -- no annotations or metadata files required
• Shows three navigable levels: pouch listing -> gear listing -> gear detail
• Displays enabled/disabled/default-on status, flags, external tool requirements (with required/optional/conflicts levels), required fonts, example gear! snippets, and pinned package versions
• Features a Doom Emacs-inspired UI with a header bar, nerd-icons support (with graceful fallback), cursor-face highlighting, and tooltips
• Opens in a right side window by default (configurable via backpack-inventory-display-action)

New Language & File Format Support

• Haskell (:editing haskell) -- with LSP, tree-sitter, and org-babel integration
• Rust (:editing rust) -- with LSP, tree-sitter, cargo integration, and org-babel support
• TOML (:editing toml) -- with tree-sitter support
• YAML (:editing yaml) -- with tree-sitter support
• Terraform (:editing terraform) -- with LSP and tree-sitter support
• Markdown (:editing markdown) -- major mode for Markdown files
• reStructuredText (:editing rst) -- major mode for rST files
• LaTeX (:editing latex) -- AUCTeX with tree-sitter support

New Default Features

• which-key is now enabled by default in :config default -- displays available keybindings in a popup as you type. Uses the built-in version on Emacs 30+, installs the package on Emacs 29.x. Disable with -which-key.
• *Help* buffers now open in a right side window (40% width) instead of splitting the current window.

New Gears & Tools

• :tools cool-motions -- smart motions: C-a cycles between first non-whitespace character and beginning of line
• :editing emacs-lisp -- Emacs Lisp support with lispy and let-completion
  Improvements
• :doctor keyword extended -- now supports requirement levels: required, optional (default), and (conflicts "other-binary"). The inventory groups tools by level when a gear uses mixed levels.
• Package display -- gear detail view now shows all pinned packages with short refs and GitHub repo info where applicable.
• Tree-sitter fixes -- correctly set hooks and remap major modes to tree-sitter modes across all language gears.
• WSL clipboard fix -- killed/copied text now correctly reaches the Windows clipboard under WSL.
• saveplace enabled -- remembers cursor position in previously visited files.
• savehist location -- history file moved to the nonessential cache directory.
• Elpaca ref updates -- elpaca now properly updates repositories when the pinned ref changes in a leaf block.
• Lexical binding -- enabled on all files that were missing it.
• Magit and friends updated -- bumped to latest pinned refs.

Documentation

• AGENTS.md -- comprehensive documentation for AI coding agents, covering architecture, boot sequence, gear file conventions, the gear!/gearp! macro system, naming conventions, the inventory system, testing, and all project rules.
• README converted to Markdown -- README.org replaced with README.md. The manual feature listing is replaced by a reference to backpack-inventory, since the starter kit is now self-documenting.

Bug Fixes

• Fix mu4e header lengths
• Fix hard-coded paths replaced with variables
• Fix add-to-list calls passing wrong type
• Fix yaml-mode activation for .yml files
