v0.1.0

First release: TaskPaper language support for Zed.

• Tree-sitter grammar with indent-based nesting (projects / tasks / notes), trailing-tag model (@name / @name(value) at end of line; emails and mid-line @words stay plain text).
• Syntax highlighting with three distinct kinds of de-emphasis: notes (comment gray), @done/@cancelled items (ghost fade cascading up to 6 levels into the subtree), and legible state-tag accents (@done muted blue, @cancelled muted amber).
• Outline panel shows projects only, by bare name, nested as in the document.
• README recipes: alt-d toggle for @done via a Zed task, keybinding scoped to TaskPaper buffers.

Install as a dev extension: clone, then in Zed zed: extensions → Install Dev Extension. See README.md.
