Add Meta/ as top-level folder for vault metadata

Context and Problem Statement

The vault had scattered meta-artifact patterns: post-mortems in Projects/, no defined home for conventions, no decision log. A clear home was needed for vault metadata distinct from vault content.

Considered Options

• Add Meta/ at root for README.md, decisions.md, and future vault metadata.
• Keep meta-artifacts scattered across content folders.

Decision Outcome

Chosen option: “Add Meta/ at root”, to consolidate conventions and decision log in one discoverable location.

Status update — superseded

Superseded by 0006-mode-based-top-level-structure and 0007-consolidate-scaffolding-into-x. With the mode-based top-level structure (3 mode folders + 4 functional folders), README.md at root is honest and discoverable; Meta/ adds a folder layer without enough volume to justify it. Premature folder creation reversed in favor of demonstrated need.
