fix(theme): replace cross-package relative style imports with package…

[cipchk]

…-name imports

Change all relative path imports (../abc/, ../chart/, ../../../form/) to package-name imports (@delon/abc/, @delon/form/) to fix pnpm strict module resolution.

• Remove @import '../chart/index.less' from default.less/variable.less (chart is not a declared dependency of theme)
• Add @import './theme-default.less' to abc/index.less for self-contained styles
• Add dist/ to generate-css.js paths to resolve package-name imports during build
• All 8 theme CSS files compile successfully with zero errors

Code Review

This pull request updates relative Less imports to package-name imports (e.g., using @delon/abc) across various theme files and adds the dist directory to the Less compiler paths in the build script. However, importing theme-default.less directly inside packages/abc/index.less breaks multi-theme support and should be avoided. Additionally, in the build script, the dist/ directory path should be ordered before node_modules/ to ensure that Less resolves package imports from the newly built files rather than stale node_modules.

Important

Importing ./theme-default.less directly inside packages/abc/index.less breaks multi-theme support (such as dark, compact, and variable themes). When other themes (e.g., theme-dark.less or theme-variable.less) import @delon/abc/index.less, they will inadvertently pull in the default theme styles and variables, leading to style conflicts, overrides, and duplicate CSS rules. Component styles should remain theme-agnostic and rely on the global theme variables being present during compilation, rather than hardcoding a specific theme import.
