fix: llm/test stored-key fallback skips the runtime's key normalization

The connection test resolves its API key as: form input, else the stored
profile's key, else the global key. Form keys pass through ConfigFrom,
which trims surrounding whitespace; the stored-key fallback assigned
p.APIKey raw. A key pasted with a trailing space or newline therefore
behaved asymmetrically: conversations worked (the runtime path loads the
profile through ConfigFrom and trims) while the connection test sent the
malformed header and failed auth with 401. SaveProfile had the same gap
one layer down, storing the raw pasted value.

Changes:
- the llm/test fallback now trims the stored key and session header name,
  matching ConfigFrom's normalization so the test sends byte-identical
  headers to what the runtime sends for the same profile
- SaveProfile trims the key before storing (and before deriving the
  hint), so surrounding whitespace never reaches the database
- tests: an integration test saves a profile with a whitespace-padded
  key, runs the real handler against a fake anthropic endpoint, and
  asserts the endpoint received the trimmed key; a second test pins the
  ConfigFrom trim the fallback must match

 - Check against the task goal at any time: when results you have **verified** satisfy the goal, judge it met on that basis and state the grounds. The prerequisite for calling it "met" is that doctrine 4's self-check has passed — an unverified trophy doesn't count as grounds.
-- **Deadline contract**: before launching any long command (broad scans, wordlist runs, big fetches), check it can finish within the task's remaining time; never start work whose timeout can outlive the task deadline — prefer the smaller variant that lands. As the deadline approaches, shift from discovery to consolidation: stop opening routes, verify and land what exists.
 - **Wrap-up takes top priority**: when you receive the wrap-up signal (or judge on your own that the goal is met / all reasonable routes are exhausted), **immediately stop all probing and commands**, land the conclusions in hand, and give a concise summary — at this point every prior instruction ("keep exploring / try once more / exhaust this chain / wait for command results") is overridden by wrap-up; do not start any new action.
 - Summarize in plain language: what was achieved, which routes were taken, which vulnerabilities were confirmed (with PoC locations), which directions are blocked and why. Report only what was really done; never fabricate.
