v2.56.0 - workspace deps as first-class, Tailwind @plugin, whole-enum fix

Monorepo workspace packages now check like external dependencies, Tailwind v4 @plugin is recognised, and fallow fix --yes removes whole export enum blocks instead of leaving dead shells.

Added

• fallow fix --yes removes unused exported enum declarations entirely. When an exported enum is unused outside its file, the whole export enum Foo { ... } block is dropped instead of leaving a non-exported zombie declaration. Covers single-line, multi-line, export const enum, and export declare enum forms, with safe descending-index ordering when other export-list lines on the same file also get rewritten. Falls back to keyword-only stripping when the enum is still referenced locally so the file continues to compile. The remove-export action description in JSON output and the fix_apply MCP tool description are refreshed so consumers see the broader behaviour.
• All-member enum-member removal folds into whole-enum removal. When fallow fix --yes would remove every member of an exported enum, the entire export enum X { ... } block is dropped in a single write instead of stripping members one at a time and leaving behind a syntactically valid but semantically dead export enum X {} shell that detection then fails to surface on the next pass. JSON output collapses the per-member entries for a folded enum into a single remove_export entry at the declaration line so consumers see exactly the edit that happened. Non-JSON output emits a stderr advisory pointing at the TypeScript build for importer cleanup, since fallow's reachability detector cannot surface a name-level dangling import once the file resolves successfully. Thanks @mjfwebb for reporting. (Closes #232)
• Tailwind v4 @plugin directive recognised in CSS, SCSS, and Vue/Svelte <style> blocks. @plugin "..." is parsed as a default import, so package plugins (daisyui, @tailwindcss/typography) are credited as used dependencies and relative plugin files have their default export marked used. Unlike SCSS @use, extensionless package names stay bare in .scss/.sass files because they are package specifiers, not local partials. Verified against daisyui's own packages/playground: without the fix, daisyui is flagged as an unused dev dependency; with the fix, it is correctly credited via @plugin "daisyui". Thanks @filipw01 for reporting. (Closes #230)

Changed

• Workspace packages treated as first-class dependencies. Workspace package names are now checked the same way as external npm packages: resolved internal-module imports whose specifier matches a workspace name are credited to package usage, so monorepo edges between workspace packages count as usage. Declared-but-unimported workspace deps now surface in unused_dependencies, and imports of a workspace package from a workspace whose own package.json does not list it surface in unlisted_dependencies. Self-references stay allowed without requiring a package to depend on itself. External plugin definitions (fallow-plugin-* / inline framework configs) now also activate per-workspace inside run_workspace_fast, so a custom plugin enabled by a workspace dependency keeps its alwaysUsed and toolingDependencies honored during real analysis instead of only appearing in fallow list --plugins. Verified against vue-core (real pnpm monorepo): the change surfaces 3 new unused-dependency findings (incl. @vue/reactivity declared but only referenced via declare module in runtime-dom) and 11 new unlisted-dependency findings on @vue/* internal packages. Thanks @filipw01 for reporting. (Closes #228)

Fixed

• Enum-member fix dedup keys on full triple so single-line folds fire. The sort + dedup of EnumMemberFix previously used line_idx alone, which collapsed distinct members of a single-line enum (export enum E { A, B }) down to one entry before detect_folded_enums could see them. The fold's all-members-removed check then concluded the body still held member B and refused to fire, leaving a half-stripped one-liner instead of the whole-block delete the fold path expects. Sort and dedup now use (line_idx desc, parent, member), so same-line distinct members survive into the fold pass.

Internal

• Enum-declaration helpers (declares_exported_enum, find_enum_declaration_range, removable_exported_enum_range, supporting identifier-boundary helpers) extracted from fix/exports.rs into a new fix/enum_helpers.rs sibling module with pub(super) visibility, so both exports.rs and enum_members.rs can share them without re-implementation. No behaviour change.
