feat: interactive field editor, document name resolution, and REPL enhancements

Major improvements to the interactive mutation workflow and overall CLI usability:

**Field-by-field mutation editor** (field_editor.rs):
- Replaces raw JSON input with per-field prompts using live __type introspection
- Pre-populates current document values as defaults via stateJSON
- Supports nested objects, enums (select picker), arrays (add/remove/replace), booleans
- Schema-aware GraphQL serialization (unquoted enum values)
- Confirmation preview showing only changed fields before executing

**Document name resolution**:
- docs get, delete, mutate, and ops now accept document names (not just UUIDs)
- New resolve_doc() helper searches all drives for matching name or UUID
- Case-insensitive name matching with fallback per-drive queries

**Drive auto-detection and selection**:
- --drive is now optional in docs list, docs get, docs tree, docs create, mutate, and ops
- Interactive drive picker (select_drive helper) when --drive is omitted
- docs list without --drive aggregates documents across all drives with Drive column

**Drives improvements**:
- drives list shows Editor column (preferredEditor metadata)
- drives get shows Editor field in detail view
- drives create uses a drive type picker queried from existing drives

**Operations (ops) improvements**:
- Shows operation input data (action.input or inputText) instead of hash
- Tries multiple query formats: paginated with action, flat with action, flat basic
- Auto-detects drive from document name/UUID

**REPL enhancements** (interactive.rs):
- Tab completion for document names/IDs, profile names, drive slugs, model types
- Animated loading spinner during API queries with immediate first-frame display
- Cursor visibility fix after dialoguer widgets hide it
- Visual command separators (dimmed header lines) before each command's output
- Guide topics work as bare commands (e.g., "overview" instead of "guide overview")
- Profile switching via config use rebuilds client and refreshes all completions
- Auto-refresh document completions after doc-modifying commands (create/delete/mutate)
- Circular tab completion mode for cycling through matches

**Config**:
- Added profile_names() helper for tab completion

 Features:
 
 - **Full CLI parity** — every command works inside the REPL (drives, docs, models, auth, access, groups, export, import, watch, jobs, sync, etc.)
-- **Tab completion** for commands, drive slugs, model types, and guide topics
+- **Tab completion** for commands, drive slugs, document names, profile names, model types, and guide topics
+- **Visual command separators** — dimmed header lines before each command's output
+- **Loading spinners** — animated feedback during API queries
+- **Profile switching** — `config use <name>` rebuilds the client and refreshes all completions
+- **Guide topic shortcuts** — type `overview` instead of `guide overview`
 - **Shell-like quoting** — single quotes, double quotes, and backslash escapes work as expected
 - **Per-command flags** — override `--format`, `--profile`, `--quiet` on any command within the REPL
 - **`--help` passthrough** — append `--help` to any command to see its usage
