v1.9.8 — MCP adoption audit

Ships the autonomous MCP adoption audit (#162): improvements to tool routing, input friction, MCP↔REST parity, and prompts, aimed at better tool selection and correct usage. 772 tests pass; verify:toolspec + verify:openapi green.

Routing & discoverability

• Server instructions rewritten into a scannable one-tool-per-line routing map with ISO-vs-NSO disambiguation; ticker-shortcut claim corrected.
• User-slang added to tool triggers ("AMT bomb", "phantom income", "cashless exercise", "over-concentrated", "downside protection", ...).
• Per-tool "call the tool, don't self-answer" cue added to the strict-input notes.

Input friction

• carryforwardCredit now optional (defaults to 0).
• Decimal-rate guardrails on volatility / growth / return / cash-rate fields (percent-vs-decimal slips now error clearly).
• terminationDate required when hasLeftCompany=true; equity_funding rejects ambiguous stacks+lots.

Consistency

• MCP↔REST field parity (volatilityDrag/haircut on amt/nso/rsu) + new toolspec-openapi-parity.test.ts drift guard.

Prompts

• Fixed a guaranteed-failure fallback in optimize-iso-exercise; exposed ticker/volatility in put/funding prompts; added the flagship plan-equity-portfolio multi-tool prompt.

Packaging

• Python adapters optionsahoy-openai-agents and optionsahoy-pydantic-ai caught up to 0.1.8 (all seven adapters now on the same line).
• Release workflows publish the npm package + python adapters and upload the optionsahoy.mcpb bundle.
