Redesigns the BUI color token system in `@backstage/ui`:
- Adds a gray scale (`--bui-gray-1` through `--bui-gray-11`)
- Adds new foreground tokens with explicit hex values (primary, secondary, disabled, positive, negative, warning, announcement)
- Introduces five new semantic color families — Accent, Announcement, Warning, Negative, Positive — each with bg-base, bg-subdued, border, fg-on-base, and fg-on-subdued variants, for both light and dark themes
- Moves all legacy tokens (`--bui-bg-solid-*`, `--bui-bg-neutral-*`, `--bui-bg-danger/warning/success/info`, `--bui-fg-solid`, `--bui-fg-danger/success/info`, `--bui-border-*`, `--bui-shadow`) into a clearly marked `/* Deprecated tokens */` section in both light and dark themes
- Updates the Spotify theme overrides to use the new accent tokens and mark legacy overrides as deprecated
- Rewrites the `Colors` Storybook story to display all token families as a live, theme-aware reference grid
- Adds a new `@backstage/no-deprecated-bui-tokens` ESLint rule to `@backstage/eslint-plugin` that warns when any deprecated BUI token is referenced in JS/TS string literals; the rule is included in the `recommended` config so it applies to all plugin authors automatically

- Fixes the `Cannot access '_AppRootElementBlueprintesm' before
initialization` crash in `@backstage/frontend-plugin-api` caused by a
self-referential import in the packaged ESM.
- Cleans up similar self-imports in `@backstage/catalog-model`,
`@backstage/core-plugin-api`, `@backstage/plugin-catalog-node`,
`@backstage/plugin-kubernetes-common`, and
`@backstage/plugin-kubernetes-node`. Value imports switch to relative
paths; type-only imports use `import type` so they're erased at
runtime.
- Adds a new `@backstage/no-self-package-imports` ESLint rule. It reads
each package's `exports` map, traverses the relative import graph from
every entry's source file, and only reports imports where the current
file is in the same bundle as the target entry (same-entry). Files
that aren't reachable from any entry (tests, scripts, orphans) are
skipped. `import type`, `package.json` imports, and cross-entry
self-imports are allowed by default; cross-entry can be opted into
with `allowCrossEntry: false`.
