Remove dead Patrol assessment and save-failure handoffs

buildPatrolAssessmentAssistantHandoff lost its last caller when the Patrol
summary card's Discuss handler was removed in eac7dfe9ef (2026-05-15), and
buildPatrolConfigurationFailureHandoff lost its last caller in 27ba85ddc6
(2026-06-23). Since then only their own tests called them. A TypeScript
compiler import graph rooted at src/index.tsx confirms no reachable file
imports either one. Removing them also drops PatrolInvestigationContextSummary,
their input and output types, and the private assessment, recent-change,
correlation and save-failure helpers that only they used (found with
noUnusedLocals until it reported nothing).

Rollup had already tree-shaken all of it: production builds of the parent
tree and of this tree are byte-identical across all 187 dist files, and the
bundle-size check passes. The presentation helpers the dead code imported
keep their live callers.

Their test cases go with them. Two cases covered branches the live finding
handoff still uses, so they now run through
buildPatrolAssistantFindingHandoffActions and buildPatrolAssistantFindingHandoff:
a typed pending action without a legacy approval id stays approval-bound,
and the finding context qualifies its resource with the record's node and
truncates long lines. v8 coverage of the surviving model code matches the
pre-removal baseline except one defensive guard the live caller cannot
reach. The raw-source guards pinned none of the removed code.

The Assistant drawer still restores saved patrol_assessment and
patrol_configuration_failure sessions, so that compatibility path stays.

The contracts described both handoffs as live producers, and described a
Patrol summary card, assessment strip, assessment readout, score chip and
header trust line that the page no longer renders. patrol-intelligence,
ai-runtime, api-contracts, frontend-primitives, security-privacy,
storage-recovery, agent-lifecycle and unified-resources now say what the
code does: those handoffs survive only as saved sessions,
the drawer, session list and API keep restoring them, rules for a returning
summary card, strip or readout are conditional, and handoff_actions and
adjacent-boundary clauses name the finding and attention handoffs that send
them today. The run-history handoff clauses also claimed the browser sends a
[Patrol Run Context] block and scoped resources; it sends the briefing and
run identity, and internal/ai/patrol_assistant_handoff.go rebuilds the rest
from the run ID.

docs/AI.md (and its public mirror) told users the legacy operational score
sits in a collapsed supporting-context section. That section and the score
are gone; the section now points at Activity > Finding options and history,
where check history lives. ai_runtime_docs_policy_test.py, its registered
proof, now pins that location and rejects the retired claim. The same file
had failed on main since 2789a15fe5 reworded the Patrol mode API sentence to
"The API retains `autonomy_level` for compatibility" without updating its
pin; the pin now matches that wording.
