Add LSP completion/code actions/rename/signature help infrastructure, fix TypeScript LSP, rebrand app identifiers

- LSP Layer: Add completion, completion_resolve, signature_help, code_action,
  prepare_rename, and rename methods to TextDocumentService and LspServerModel
- Types: Add CompletionItemData, CompletionResult, SignatureHelpResult,
  CodeActionData, PrepareRenameResult, RenameResult, FileEdits
- Feature Flags: Add LspCompletion, LspCodeActions, LspRename, LspSignatureHelp
- Client Capabilities: Declare completion, signature help, rename, and code
  action capabilities so servers advertise these features
- Completion UI: Add completion state machine with debounced triggers, fuzzy
  filtering, positioned overlay menu, and edit application
- TypeScript LSP: Switch to npx for running typescript-language-server (handles
  download/caching automatically, survives node version switches)
- PATH Resolution: Add interactive shell PATH fallback for LSP server discovery
  and spawning (fixes nvm/fnm/volta users)
- App Identity: Rebrand from com.samsung.Galaxy/dev.warp.WarpOss to
  samsung.galaxy.GalaxyOss across bundle IDs, URL schemes, and plists
- Add scripts/reset-galaxy.sh for clean slate testing
- Galaxy status messages and other in-progress work
