M5b plan: task 06, memoryd refuses and flags through sanitize

memoryd's writes go through bxcore::sanitize::refuse, then flag; check.rs
and its test go. A refused write answers with the rule's sentence and is
logged with the rule's name; a flagged identity write becomes untrusted
notes with the rule in the answer, the journal (new optional field `flag`)
and the log, and is never staged for review; the block leaves out an
entry that breaks a refuse rule and logs the rule. The three runbook
entries the new pointers need are given here as fragments, because the
gate's runbook check fails on a pointer without its entry.

Checks, on titan (rustc 1.98.1, clippy 0.1.98):
- given tests fail before as the task says: 7 failing in edit, serve and
  serve_sanitize; files and sanitize do not compile (E0609; E0432, E0609,
  E0615)
- the task's edits, parsed from the task file and applied to a fresh
  ref-05 worktree with its own target/, give a tree byte-identical to the
  reference; its gate: ok, 1033 tests; /private/tmp unchanged
- 26 one-line mutations of the reference, each caught by the given tests
- new tests stressed under load: 30 runs, 0 failures
- no chat-template tag and no whole fake key in the task or given files
