Magnus HedemarkandGitHub f9db3dbe4b fix(calculator): honest burn-multiple and runway labels, surface model assumptions (#274)
* fix(calculator): honest burn-multiple and runway labels, surface model assumptions

- Burn Multiple now reports Graham's metric (net burn / net new ARR);
  the net burn / MRR ratio is reported separately as Burn to Revenue.
  The qualifier (efficient/healthy/warning/critical) is derived from the
  real burn multiple, so DEAD verdicts no longer print 'efficient'.
- ALIVE verdicts no longer print a misleading 'Runway: 120 months'
  (projection cap); output now shows 'Projected cash-out' with 'none
  within the 10-year projection' when the company never runs out.
- Model assumptions (fixed/variable burn split, variable burn ratio,
  growth decay, projection cap, safety buffer) are now surfaced in the
  human report and in JSON model_assumptions.
- SKILL.md: fix dead paulgraham.com/default.html source URL to aord.html;
  update output-field docs and examples to real model output.
- Add regression tests (tests/integration/test_default_alive.py).

Fixes #272
Fixes #273

Magnus Hedemark d8a11c2a4b Add yc-default-alive-calculator and yc-weekly-growth-compass skills
Two research-grounded entrepreneurial tools based on Paul Graham's Y Combinator
frameworks, with companion CLI scripts and extensive reference material.

yc-default-alive-calculator:
- Paul Graham's 'Default Alive / Default Dead' framework as a deterministic CLI
- Month-by-month financial projection engine with growth decay modeling
- Burn multiple analysis, lever identification, and actionable verdict
- Zero external dependencies (Python 3.9+ stdlib only)
- 2 reference docs (framework deep-dive, fundraising context)

yc-weekly-growth-compass:
- Paul Graham's 'Startup = Growth' framework as an operational weekly tool
- Single-period and time-series growth rate computation
- YC benchmark classification (1% concerning -> 10%+ outstanding)
- Compound growth projections, doubling time, and decision compass
- Zero external dependencies (Python 3.9+ stdlib only)
- 2 reference docs (framework essay breakdown, compound growth table)

Both skills follow the Agent Skills open format (agentskills.io spec v1.0).
