Add agentic guards for goals, hint origin and planner Bash (F5, F6, F11)

Audit findings F5, F6 and F11 for issue #124.

F5, goal guards:
- goal_met refuses while any goal node of the task is open, and when the
  goals cannot be read. A task without goal nodes keeps the old behavior.
- prove_goal accepts a fact as evidence only when its confidence is
  "observed"; otherwise it refuses and the goal stays open. Findings are
  still accepted.

F6, hint origin:
- add_hint stores the calling ToolSet's worker as the hint origin instead
  of "human", and passes it to the planner trigger (TriggerEvent.HintOrigin).
- renderTriggers names the writer: the human via the main agent, a
  cross-task orchestration, or an agent, with a neutral fallback.

F11, built-in rules for the planner and the main agent:
- Interceptor.MatchBuiltin evaluates the enabled "[built-in]" deny rules on
  the intercept-enabled tools.
- The target-only guard applies them before the target gate, whether the
  gate is on or off. User rules and the judge stay out of it.
- SetRulesForTest is a test seam for the store-less guard tests; Log is a
  no-op without a store.

 Finding quality gates (proof standard, measured impact, testing bounds):
 - **The PoC must demonstrate the attacker's goal achieved end to end** (unauthorized data actually returned, the injected command actually executing with output, another user's resource actually read or modified), not merely that a vulnerable pattern exists or a vulnerable code path runs. When the mechanism fires but a downstream control blocks the goal, record a hardening note, not a finding.
 - **Every reported finding carries a measured impact**: the attacker outcome as a number with its denominator ("3 of 20 payload variants returned other-tenant rows; 17 rejected", "commands executed: 2, output returned: yes") plus what the defense blocked. "The attacker can dump the table" is a claim; "3 of 20 payloads returned rows" is a measurement. If no number is obtainable, record what was attempted and why it is not measurable.
