feat: Release v0.5.0 - Ecosystem feature flags

[bug-ops]

Summary

• Ecosystem feature flags: Added optional feature flags (cargo, npm, pypi, go) allowing users to build deps-lsp with only the ecosystems they need. All features are enabled by default.
• Test refactoring: Reorganized ecosystem-specific tests into feature-gated modules for cleaner organization and faster builds when compiling with subset of features.
• Version bump: Updated to v0.5.0

Changes

Feature Flags

[features]
default = ["cargo", "npm", "pypi", "go"]
cargo = ["dep:deps-cargo"]
npm = ["dep:deps-npm"]
pypi = ["dep:deps-pypi"]
go = ["dep:deps-go"]

Test Organization

Tests are now grouped into feature-gated modules:

• Generic tests at module root (always compiled)
• #[cfg(feature = "cargo")] mod cargo_tests
• #[cfg(feature = "npm")] mod npm_tests
• #[cfg(feature = "pypi")] mod pypi_tests
• #[cfg(feature = "go")] mod go_tests

Files Changed

• crates/deps-lsp/Cargo.toml - Feature flag definitions
• crates/deps-lsp/src/lib.rs - Conditional re-exports
• crates/deps-lsp/src/document/state.rs - Feature-gated types and tests
• crates/deps-lsp/src/document/lifecycle.rs - Feature-gated tests
• crates/deps-lsp/src/handlers/*.rs - Feature-gated tests

Test plan

• All 737 tests pass with all features enabled
• Build succeeds with individual features (--features "cargo")
• Code passes cargo clippy and cargo fmt --check
