Twig 3.1.0 — Reliable data, a clearer path

This release hardens the Rust rewrite, improves everyday navigation, and brings
the website and documentation into the same repository as the application.

Correctness and privacy

• Source changes automatically select a new content-validated cache. Failed or
  cancelled imports never publish partial data; concurrent loads are isolated.
• Mixed arrays preserve order, large unsigned integers stay numeric, and quoted
  bracket paths distinguish punctuation-containing keys from nested keys.
• Unicode previews/highlights no longer slice through UTF-8. Terminal and worker
  guards restore state and cancel unfinished work on exit.
• Private cache permissions, automatic retention, --no-cache, and
  --clear-cache give local data a defined lifecycle.
• The RustSec-flagged YAML dependencies are replaced with serde_norway.

Navigation and CLI

• JSON node-event parsing uses bounded insertion batches. Navigation uses
  256-row pages and keeps the deepest columns visible; inspector previews have
  explicit limits.
• Mouse selection/scrolling, Vim movement, Enter-to-open, Home/End, and g/G.
• Literal substring search in document order. % and _ are literal characters.
• Copy complete selected values up to 10,000 nodes, or show an explicit size
  error; copied data is never silently depth-truncated.
• --fix --print composes correctly, JSON indentation works with -o, YAML
  detection is case-insensitive, and YAML print supports document streams.
• JSON stdin for noninteractive modes, -i indentation, and the legacy -v
  version alias. Output-file replacement is atomic; CLI output is plain text.
• Automatic legacy macOS config import when the new config is absent.

Distribution and documentation

• Fail-closed checksum verification with Linux/macOS tools, working piped help,
  pinned source installs, and destination-aware atomic installation.
• CI on stable and Rust 1.88 across Linux, macOS, and Windows, plus offline
  installer tests, dependency checks, and a cold-ingestion resource budget.
• Releases build the verified tag commit and publish checksums, provenance,
  build metadata, and these notes. Automatic releases wait for successful CI.
• A complete website rewrite with an interactive sample explorer, responsive
  layout, accessible controls, and guides generated from repository Markdown.

Upgrade notes

Install with curl -fsSL https://twig.wtf/install.sh | bash, or download the
archive for your target. Source builds require Rust 1.88+ and a C compiler.

Old caches are ignored; close Twig and use twig --clear-cache to remove them.
Punctuation keys now use paths such as .regions["us-east-1"]. JSON duplicate
keys and multiple top-level values are rejected. Help is ?; h moves back.
See the migration guide.

YAML parser memory, large scalars, full exports, and substring scans still have
input-dependent resource costs. TUI YAML supports JSON-compatible values.
Clipboard persistence after exit depends on the desktop manager. Native binaries
are not OS code-signed/notarized; Linux targets use GNU libc. See the guide for
cache privacy and platform limitations.
