darn v0.3.0

Patchwork alignment, porcelain mode, property tests, and cross-platform CI.

Highlights

Patchwork schema alignment — Directory and file documents now match Patchwork's FolderDoc/FileDoc conventions (title/docs/url fields, extension/mimeType, automerge URL encoding via bs58check)
Porcelain output mode (--porcelain) — Machine-readable tab-separated output on every command; no spinners, colors, or box-drawing characters. --force implied.
File attributes (.darnattributes) — Gitattributes-style rules for overriding text/binary detection. Includes sensible defaults for lockfiles, source maps, and minified assets. Files over 1 MB default to binary.
TLS backend selection — native-tls (default) for macOS/Linux-gnu, rustls for musl static builds. No OpenSSL needed for statically-linked binaries.
Property-based testing — 13 modules converted to bolero property tests covering roundtrips, idempotency, and validation invariants.

--porcelain global flag for scriptable output on all commands
-v/--verbose global flag enables debug-level tracing
.darnattributes file for text/binary/auto classification per glob pattern
darn clone now accepts automerge URLs (automerge:<bs58check>) in addition to raw IDs
Parallel file discovery with ShardedDirCache and progress callbacks
Remote file deletion detection — files removed on the remote are cleaned up locally
Streaming UTF-8 validation (64 KB chunks instead of full-file reads)

Feature flags: native-tls (default) and rustls on both darn_core and darn_cli
musl targets build with --no-default-features --features rustls (pure Rust TLS, no system OpenSSL)
tungstenite dependency trimmed to default-features = false to avoid pulling in OpenSSL transitively
Release profile: lto = "fat", codegen-units = 1, panic = "abort", strip = "symbols"

build.yml — 5-target matrix (x86_64/aarch64 × gnu/musl + aarch64-apple-darwin) plus Nix build; automatic nightly releases
test.yml — ubuntu + macOS matrix plus Nix-based test run
quality.yml — build, check, nightly rustfmt, clippy with -D warnings
cargo-audit.yml — daily + on-push dependency vulnerability scanning
spellcheck.yml — markdown spellcheck with custom dictionary

13 modules now use bolero property tests (path, file, directory, refresh, peer, manifest, discover, ignore, attributes, workspace/id, workspace/registry, file/name, file/metadata/permissions)
Once-guarded test signer ensures CI works without pre-existing ~/.config/darn/signer/
Tests migrated from .expect() panics to -> TestResult with ?
Removed tests that only exercised external libraries

File discovery now respects .darnattributes and includes dotfiles like .darnignore
Large files (>1 MB) default to binary storage, avoiding expensive character-level CRDT overhead
Fixed tungstenite default features pulling in OpenSSL on musl targets
Fixed feature unification where workspace dependency defaults re-enabled native-tls

Automerge document schema updated to Patchwork conventions — existing v0.2 workspaces need migration
anyhow replaced with eyre/color-eyre
