CR-014 - bodies carry customer context and the link carries the content

Nick's decision, 2026-08-20: 'email bodies provide links back to the system.
we can talk about customers we just cant exposed their confidential
documents.' The T7.6-era rule (no customer IP at all, so number + link only)
is refined: context IN, content OUT.

- wp_titled() and wp_where() compose 'number - title' and the CR-004
  location (structured paths first, legacy free text second); the where-line
  is dropped entirely when unset rather than mailing 'Where: '.
- assign, qa-ready, qa-reject and hold bodies gain title + location. The
  scope summary the original CR asked for stays OUT - scope text is document
  content; the link is its summary. Rejection comments stay on the package.
- hold_body gains the house footer it alone lacked.
- kitting and material-request bodies adopt wp_titled for the same identity
  line (their delivery-location rule is unchanged).
- notify.py's docstring states the new rule where the transport documents it.

Pins flipped WITH the rule, reasons in code: qa_gate_check's location canary
is now asserted PRESENT in QA bodies; a new DESC_CANARY (document content) is
asserted absent from every message (40 -> 41 checks). The sink also gains a
decoded-body view: the em-dash switches smtplib to quoted-printable, whose
column-76 soft breaks made raw-payload substring pins pass or fail on luck of
line position - content pins now read the decoded body, header pins still
read the wire payload.

Battery: qa_gate_check 41/41, kitting_notify_check 17/17, mreq_check 19/19.

Items: CR-014 (rule per decisions-2026-08-20.md), CR-011 pins.
