fix(types): remove phantom time_pressure field from VulnInputs

[dmchaledev]

Problem

The published index.d.ts advertises an optional time_pressure field on the public VulnInputs interface:

export interface VulnInputs {
  target_hosts: number;
  scan_intensity: 'light' | 'medium' | 'aggressive' | 'continuous' | string;
  scan_frequency: 'daily' | 'weekly' | 'monthly' | 'quarterly' | string;
  scan_window?: number;
  time_pressure?: 'light' | 'medium' | 'aggressive' | 'continuous' | string;  // ← does nothing
  scanning_tools: string[];
  ...
}

But the calculation engine never reads time_pressure. All timing is derived from scan_intensity (via TIME_MULT) and scan_window:

const timeMult = TIME_MULT[data.scan_intensity] ?? 1.0;   // hailbytes-vuln-calculator.js:129

time_pressure appears in exactly one place in the whole repo — this type declaration:

$ rg time_pressure
index.d.ts:10:  time_pressure?: 'light' | 'medium' | 'aggressive' | 'continuous' | string;

It was already removed from the test suite in 82e5a30 ("use scan_window instead of non-existent time_pressure field"), and it's absent from the README's Input Schema table. index.d.ts was the last stale reference left behind.

Impact

index.d.ts ships in the npm tarball (it's listed in package.json's files), so this is the type contract every TypeScript/IDE consumer sees. A developer who sets time_pressure — reasonably expecting it to influence scan timing — gets a value that is silently ignored, with green typechecking and no error. The advertised API and the actual behavior disagree.

Fix

Remove the dead time_pressure field so the shipped type matches the engine. No runtime/source/behavior change.

The interface keeps its [extra: string]: unknown index signature, so arbitrary extra fields are still permitted — this isn't a breaking narrowing for any input that actually affects a result.

Verification

$ rg time_pressure          # no matches remain
$ node --test test/*.test.mjs
# tests 65
# suites 9
# pass 65
# fail 0

Self-contained: one-line deletion in index.d.ts, no API or behavior change for existing consumers.
