v1.0.0 — declarative DSL rewrite

Complete rewrite around a macro-based DSL that compiles to introspectable data, replacing the keyword-list meta(...) approach.

Highlights

• New macros: authorize, load, authorize_owner, loaders/loader. Auth rules read like English: authorize "close_todos", when: arg(:state) == "CLOSED".
• Conditions compiled to data form — {:cmp, [:eq, {:arg, :state}, ...]} — fully introspectable, hashable, serialisable.
• Public introspection API + mix absinthe_permission.audit Mix task with text or JSON output.
• Telemetry on every decision and loader call.
• Custom exceptions with helpful messages (MissingContextError, UnauthorizedError, CompileError).
• Fail-loud on missing context (was fail-open in v0.1).
• No String.to_atom on data — Sobelow-clean.
• AGENTS.md cookbook for AI coding agents.

Compatibility

• Bumped Absinthe to ~> 1.7, telemetry to ~> 1.0, Elixir to ~> 1.14.
• Not API-compatible with v0.1.x. See CHANGELOG.md for the full migration table.
