Two selects that never wrote anything, and a queue

The approval card in Auto mode and the missing /effort were one bug. Both
selects hung their hx-patch on an empty sibling form reached by form="…",
and htmx binds a trigger to the annotated element: change fires on the
select and bubbles to its ancestors, which a sibling is not. The live rows
read agent_mode=manual and params_json={} while the browser showed Auto and
Effort: high. policy.py was never involved.

The verb moves onto the control; the empty form stays as value scoping,
which is the half of the CLAUDE.md note that was right. conftest gains
control_named so a test asserts the element carrying the name carries the
verb, rather than asserting the markup that was there throughout.

The composer's highlight was a third instance of the same carelessness in
CSS: .tok-mention is written for the transcript and scoped to nothing, so
the mirror painted its token in accent-coloured monospace over the
textarea's own text. Scoped under .msg; the mirror restates transparency
and font rather than inheriting them, and bleeds by box-shadow.

/effort is now offered before the first prompt and _new_chat reads it.
/index re-walks the project directory on demand, file_write drops the
listing it just invalidated, and the index ladder falls through to SFTP on
a host that refuses exec instead of returning nothing.

A second message during a reply is queued rather than starting a second
concurrent generation: a real Message row with queued set, so it survives a
restart and can be withdrawn. _drain hands one on at the end of a reply,
_inject takes one in at a tool-round boundary so an agent can be steered
mid-task. Stop leaves the queue undelivered. The terminal's Auto toggle
becomes off/copy/send, and send posts straight to the chat without touching
the composer.

@ now offers notes, skills, this chat's attachments and a URL to fetch; a
knowledge base attaches as a reference rather than a copy. copy_document
carries provenance, which was the one attach path that dropped it.

Also fixes an unrelated live bug: the round loop compared against the
global MAX_ROUNDS of 3 while sizing itself from the agent budget of 40, so
agent replies stopped after three rounds and reported forty.
