merge: sync with upstream/dev (oh-my-opencode v3.14.0+)

Merge 3185 upstream commits from code-yeongyu/oh-my-opencode dev branch.
Accept upstream structural refactors while preserving Arcanea branding
in package.json. Arcanea agent overlay files preserved in src/agents/arcanea/.

Resolved conflicts:
- package.json: keep Arcanea name/URLs, accept upstream deps/version
- src/agents/: accept upstream restructure (utils.ts deleted, builtin-agents.ts added)
- src/config/schema.ts: accept modular schema/ directory restructure
- src/shared/config-path.ts: removed (upstream deleted, functionality moved)
- src/tools/lsp/utils.ts: removed (upstream deleted, functionality split)
