Add completion spec: nmap

[lucieleblanc]

Summary

Adds command completion support for nmap (network mapper/scanner).

Changes

JSON Spec (command-signatures/json/nmap.json)

Comprehensive completion spec covering ~80 options across all nmap categories:

• Target specification: -iL, -iR, --exclude, --excludefile
• Host discovery: -sL, -sn, -Pn, -PS/-PA/-PU/-PY, -PE/-PP/-PM, -PO, -PR, --traceroute, -n/-R, --dns-servers, etc.
• Scan techniques: -sS/-sT/-sA/-sW/-sM (TCP), -sU (UDP), -sN/-sF/-sX, -sY/-sZ (SCTP), -sI, -sO, -b, --scanflags
• Port specification: -p, --exclude-ports, -F, -r, --top-ports, --port-ratio
• Service/version detection: -sV, --version-intensity, --version-light, --version-all, --allports
• OS detection: -O, --osscan-limit, --osscan-guess/--fuzzy, --max-os-tries
• NSE scripting: -sC, --script, --script-args, --script-help, --script-updatedb
• Timing/performance: -T (with named templates), --min/max-hostgroup, --min/max-parallelism, RTT timeouts, --min/max-rate, --nsock-engine
• Firewall evasion: -f, --mtu, -D, -S, -e, -g/--source-port, --proxies, --ip-options, --ttl, --spoof-mac, --badsum
• Output: -oN/-oX/-oS/-oG/-oA, -v, -d, --reason, --open, --resume, --stylesheet
• Misc: -6, -A, --datadir, --send-eth/--send-ip, --privileged/--unprivileged, -V/--version, -h/--help

Generators (command-signatures/src/generators/nmap.rs)

• network_interfaces (for -e flag): Cross-platform — uses /sys/class/net on Linux, ifconfig -l on macOS, falls back to parsing ifconfig output
• nse_scripts (for --script and --script-help flags): Lists .nse files from common nmap data directories (/usr/share/nmap/scripts, /usr/local/share/nmap/scripts, /opt/homebrew/share/nmap/scripts) plus built-in script categories (all, auth, broadcast, brute, default, discovery, dos, exploit, external, fuzzer, intrusive, malware, safe, version, vuln)

Static Suggestions

• Timing templates (-T): 0-5 with named aliases (paranoid, sneaky, polite, normal, aggressive, insane)
• Version intensity (--version-intensity): 0-9
• Debug levels (-d): 0-9
• IP options (--ip-options): S, R, L, T, U
• nsock engines (--nsock-engine): epoll, kqueue, poll, select

Validation

• npm run format ✅
• script/presubmit passes (54 tests, 0 failures, clippy clean) ✅

Generator Verification Screenshots

network_interfaces generator (nmap -e <Tab>)

Shows network interface names (eth0, lo) with "Network interface" descriptions:

nse_scripts generator (nmap --script <Tab>)

Shows NSE script names (acarsd-info, address-info, afp-brute, etc.) with "NSE script" descriptions:

Both generators produce meaningful completions in a local Warp build.
