The import/no-cycle refactor had moved IInsertEvent, IDeleteEvent, and
ICircularList into Types.ts, with CircularList.ts re-exporting the event
types from there. That split the list abstraction from its implementation
and pulled Types into the circular-list dependency graph.
Define IInsertEvent, IDeleteEvent, and ICircularList in CircularList.ts
alongside the CircularList class. CircularList.ts now depends only on
Lifecycle and Event, not Types.ts.
Remove those definitions from Types.ts (and the unused Emitter import).
Update callers to import list types from CircularList:
- buffer/Types.ts (IBuffer.lines)
- DecorationService.ts (buffer line insert/delete handlers)
- browser TestUtils.test.ts (mock buffer lines)
Types.ts no longer imports or re-exports circular-list types, preserving
the acyclic Types -> buffer/CircularList boundary.

Enable oxlint's import/no-cycle rule (import plugin) so circular module
dependencies are caught in CI, similar to eslint-plugin-import/no-cycle
and biome no-import-cycles discussed in the issue.
Relocate shared types and dependencies to remove cycles under src/common:
- Types.ts: host IInsertEvent, IDeleteEvent, IParams, UnderlineStyle,
IBuffer, and IBufferSet; drop imports from CircularList, buffer/Types,
parser/Types, and Services
- CoreTerminal.ts: define and export ICoreTerminal
- ServiceRegistry.ts: define IServiceIdentifier (break Services registry loop)
- UnicodeService: stop constructing UnicodeV6; CoreTerminal registers the
default v6 provider after service creation
- buffer/Types.ts and parser/Types.ts: re-export moved types for callers

Fixes https://github.com/xtermjs/xterm.js/issues/5896
TypeScript path mappings for common/*, browser/*, and headless/*
were not rewritten in emitted JavaScript, which forced webpack resolve
aliases and NODE_PATH workarounds so runtime could resolve modules.
That added build complexity and broke tooling such as ESLint import/no-cycle.
Changes:
- Convert ~750 imports across src/, addons/, and test/ to relative paths
- Remove common/browser/headless paths and src catch-all mappings from tsconfigs
(keep @xterm/addon-* demo and addon typings paths)
- Remove webpack resolve.alias for common, browser, headless, and vs
- Drop NODE_PATH from unit tests, benchmarks, and VS Code launch config
- Fix addon-image IIPImageStorage to import ./Types after removing catch-all *
Verified: npm run build, esbuild, package, package-headless
