* feat: replace React/Tauri/NPM frontend with pure Rust iced 0.13 GUI

Eliminates all NPM/JavaScript dependencies by migrating the Spin v12
frontend from React + Tauri to a native Rust GUI using iced 0.13 and
wry 0.44 for the embedded browser WebView.

Changes:
- Cargo.toml: remove tauri/tauri-build, add iced 0.13 + wry 0.44 + dirs 5
- build.rs: replace tauri_build::build() with empty stub
- storage/mod.rs: init(&Path) + get_store() without AppHandle
- cef/mod.rs: init(&Path) instead of &AppHandle
- hivemind, mcp, session, investigation: init() with no params
- All 9 command modules: strip #[tauri::command] macros, remove AppHandle
- commands/identity.rs: use core::identity::ProxyConfig (no local dup)
- lib.rs: rewrite as iced::application() runner using dirs crate
- main.rs: fn main() -> iced::Result
- New ui/ module: app.rs (SpinApp), state.rs, messages.rs, theme.rs
- New ui/views/: layout, title_bar, tab_bar, nav_bar, browser_view,
  side_panel, identity, hivemind, mcp, osint, privacy, investigation,
  settings — replacing all React .tsx components
- Delete: app/src/ (React frontend), package.json, vite, tsconfig, etc.

Result: zero NPM packages, pure Rust, single Cargo build.

* fix(install): remove all NPM/Node/Tauri-CLI references from installer

The installer was still written for the old React/Tauri/NPM stack.
Updated for the pure Rust iced 0.13 migration:

- Remove Node.js version check and install_node_* functions
- Remove Tauri CLI check/install (no longer needed — plain cargo)
- Remove MIN_NODE_VERSION variable
- Add CARGO_DIR ($APP_DIR/src-tauri) and BIN_PATH variables
- Step 4: cargo fetch instead of npm install
- Step 5: cargo check instead of tsc + npm run build
- Step 6 (shortcut): builds release binary, Exec points to binary
- verify_install: checks Cargo.toml, Cargo.lock, release binary
  (no more package.json / node_modules / dist checks)
- check_for_updates: reads version from Cargo.toml, not package.json
  runs cargo fetch after git pull instead of npm install
- Menu option 2 (update): cargo fetch, no npm
- Menu option 6: replaced "frontend-only fallback" with build binary
- Desktop shortcut icon: assets/icon.png (repo root)
- macOS hint: sudo cp binary to /usr/local/bin
- Banner updated with "Zero NPM · Pure Rust · iced 0.13 · wry"

* fix: update READMEs for pure Rust stack and fix entity_extractor compile error

- Rewrite root README.md: replace Tauri/React/NPM badges and docs with
  iced 0.13 + wry 0.44; fix stale anchor links; remove broken web app link;
  update Quick Start, Prerequisites, Installation, Tech Stack, and
  Security Model sections; update Acknowledgments
- Rewrite app/README.md: replace npm Quick Start and Tauri/React/Redux
  tech stack with cargo-based commands and iced 0.13 architecture diagram
- Fix entity_extractor.rs: change URL_REGEX raw string from r"..." to
  r#"..."# so the \" inside the character class does not prematurely
  terminate the raw string, eliminating 25 cascade compile errors

https://claude.ai/code/session_015EF4PRbxogid2koYhyGP1Y

* fix(ui): fix 7 compile errors and clean up 33 unused-import warnings

hivemind.rs:
- EntityType::Coordinates → EntityType::Coordinate (correct variant name)
- Remove EntityType::SocialHandle arm (variant does not exist)
- Add move to container style closure to satisfy borrow checker
  (iced::Color is Copy so move is safe)
- Remove unused Length import

mcp.rs:
- Replace row![].spacing(4).wrap() + btns.push() pattern with
  Row::with_children(Vec<Element>) — iced 0.13 Row::wrap() returns
  row::Wrapping which has no push() method
- Remove dead RowWrap trait and impl
- Remove unused Length and ghost_btn_style imports

layout.rs, nav_bar.rs, osint.rs, privacy.rs:
- Remove unused Length import from each
- Remove unused keyboard import from nav_bar.rs
- Remove unused ghost_btn_style import from osint.rs

https://claude.ai/code/session_015EF4PRbxogid2koYhyGP1Y

* fix(ui): fix 7 compile errors, clean warnings, bump to v12.1.3

Compile errors fixed:
- fingerprint.rs: add `use rand::seq::SliceRandom` so .choose() resolves
- app.rs: InvestigationsLoaded — convert Investigation→InvestigationSummary
  via .to_summary() to match the Vec<InvestigationSummary> variant
- app.rs: SaveApiKey — set_claude_api_key returns Result<bool>, not
  Result<()>; changed Ok(()) to Ok(_)

Unused import/variable warnings cleaned:
- settings.rs: remove checkbox, Length; drop dead key_display variable
- side_panel.rs: remove Alignment, Length, rule
- tab_bar.rs: remove Length; prefix theme/status → _theme/_status
- title_bar.rs: remove button, Length
- layout.rs: prefix sidebar_width → _sidebar_width

Version bump 12.0.3 → 12.1.3:
- Cargo.toml, tauri.conf.json, settings.rs version string
- README.md: all version references, What's New section updated with
  v12.1.3 bug fix notes, D3.js references replaced with native Rust
  equivalents (iced 0.13 has no D3.js)
- app/README.md: version header
