v3.5.0: REPL quick-wins (Tab-complete, @file/@dir/@line, multiline, /theme, /attach, /context) + installer + README

REPL (rustyline Helper):
- Tab autocomplete for /commands and @filesystem-paths.
- @path attach: @file, @folder, @file:LINE / @file:START-END fold scope files /
  stack traces into the agent context; /attach <path> and /context to manage.
- Multiline input: end a line with `\` to continue (validator-driven).
- /theme color|mono, /config (=/show); history (↑/↓) persists as before.
- Attachments are merged into the run's instruction context.

Install:
- setup.sh: `curl … | bash` — auto-installs Rust, clones to ~/.neurosploit,
  builds release, links neurosploit into ~/.local/bin; idempotent; env-tunable.

README: v3.5.0, 🧠 (back to "neuro"), one-line install section, neurosploit-on-PATH usage.

+## 📦 Install (one line)
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/JoasASantos/NeuroSploit/main/setup.sh | bash
+```
+
+The installer auto-installs Rust if needed, clones the repo to `~/.neurosploit`,
+builds the release binary, and links `neurosploit` into `~/.local/bin`. Re-run it
+any time to update. Tweak with env vars: `NEUROSPLOIT_REF` (branch/tag),
+`NEUROSPLOIT_DIR`, `PREFIX`.
+
+Prefer to build by hand?
+
+```bash
+git clone https://github.com/JoasASantos/NeuroSploit && cd NeuroSploit/neurosploit-rs
+cargo build --release      # → target/release/neurosploit
+```
