v1.1.1 — orchestrator FP + exit-attribution + inert-edit fixes for the Class-1 evidence layer

Three fixes, each surfaced by putting v1.1.0 through two Fable passes (a
break-it red-team + an architectural review) and a real subagent transcript:

• SubagentStop falsely accused every test-running subagent of "no test ran":
  the sidechain filter (correct for the main path) deleted the subagent's own
  evidence while keeping its claim, and the stop also wrote shared session
  state against the ORCHESTRATOR's contract. main() now branches on
  hook_event_name===SubagentStop: parse the subagent's own file with
  includeSidechain, grade its claim against its own evidence, write nothing
  shared, demote block->warn. Empty/unreadable transcript -> abstain.

• Exit-status attribution was wrong across every shell connector: && echo ok
  laundered a crash, cd x && npm test fired on a test that never ran,
  || true/pipe/; laundered a red into a green. Replaced with a
  connector-aware rule (|| -> null; exit belongs to the last ;/newline
  statement; within the last statement attributable iff every non-family
  segment is infallible {echo,true,:}; a null latest run abstains and never
  displaces an earlier red). Command-position anchor (FAM_CMD_RE) so a runner
  name in an argument (grep vitest ...) is not a family run.

• Stale-green fired on inert edits (a comment on a code line, whitespace
  reformat): the mutation-is-code test is now the normalized code portion
  (splitCodeComment + collapsed whitespace), so comment/whitespace deltas
  don't count while string/code changes still do.

The review found five live defects in the half-finished implementation, two of
them the exact laundering/FP classes the changelog claimed closed (trailing
;/newline laundering, lone-& FP, redirected-echo FP, runner-name-in-arg
FP/FN, empty-subagent-transcript re-mint) -- all fixed at root with pinned
regressions.

Self-check 566 -> 596; legacy committed suite 509/509 (zero drift);
red-team 14/14; corpus unchanged (17/23 at-capture).
