Names the BasicHTTP front in Status and owns

[johnnyt]

What

README only. ## What this package owns and ## Status said every owned
piece is built and named four tables, but neither named the BasicHTTP front
or the opt-in location table, and neither named the configuration's
:around_delivery option. This names them, adds the token sentence to the
BasicHTTP front section, and makes the ledger bullet true for timers.

• ## What this package owns: two bullets, "The BasicHTTP front"
  (StatifierRouter.BasicHTTP, StatifierRouter.BasicHTTP.Front, the
  opt-in location table) and "The whole-delivery wrapper"
  (:around_delivery), each pointing at the section that describes it.
• ## What this package owns, the recorded outcome bullet: "every delivery
  attempt" becomes "every delivery attempt this package routes", and a
  timer firing into an execution is named as not routed here and writing
  no routing-ledger row. No code under lib/ delivers a timer fire; the
  timers are statifier_oban's, as ## What it does not own already says.
• ## Status: one sentence naming StatifierRouter.BasicHTTP,
  StatifierRouter.BasicHTTP.Front and the opt-in location table that
  StatifierRouter.Migrations.up_locations/1 creates outside the version
  walk, and one naming :around_delivery as optional, nothing called when
  it is left out.
• ## A BasicHTTP front: a paragraph after the bearer-capability one,
  matching ADR-0002's Note of 2026-10-02 on the query log: the token is
  part of the execution's persisted state, bound on the create and on
  every step and at rest in the clear unless the host passes an encrypting
  :blob_type to statifier_persistence; this package keeps it out of its
  own query log only, and the query telemetry event still carries the
  parameters; rotate, and never run a production repo or logger at
  :debug.

Gate

README.md is a gated path here (also_gated_paths), so the full
mix quality ran green on this branch's tree before the push; the commit
was made on that same tree. No changelog fragment:
documentation only, per changelog.d/README.md.

Review

Gate tier (docs only): the pre-request review round ran in-turn. Each new
sentence was checked against main: the :basichttp and :around_delivery
rows of StatifierRouter.Config, StatifierRouter.Migrations.up_locations/1,
StatifierRouter.Schema.Location, the "Wrapping a whole delivery" section,
and the ADR-0002 Note of 2026-10-02 on the query log. No record is edited.
