fix(inline-links): drop the trailing context-menu box from inline task links

[nelsonlove]

The problem

Inline task links carry an odd gap after them in running prose.

The cause is .task-card__context-menu, which is opacity: 0 until its card is hovered. That hides it but keeps its box in layout:

https://github.com/callumalpass/tasknotes/blob/main/styles/task-card-bem.css#L827-L839

.tasknotes-plugin .task-card__context-menu {
    width: 14px;
    height: 14px;
    opacity: 0;
    margin-left: auto;
}

In the card layouts this costs nothing - the element sits at the end of a row of its own, and margin-left: auto parks it against the edge. In --layout-inline it is 14px of dead space after every link, plus the row's 4px gap, and margin-left: auto does nothing inline.

Measured on a live vault, walking the rendered inline widgets and taking the distance from the right edge of .task-card__content to the right edge of .task-card__main-row:

	trailing space
before	14px (0px on links without the element)
after	0px

The change

One rule, scoped to the inline layout. Card, kanban and list layouts are untouched.

Removed rather than hidden-until-hover: an invisible target inside a sentence cannot be aimed for, and the link still has its right-click menu. If you would rather keep it reachable, position: absolute or a zero-width box that expands on hover would also remove the space - happy to switch.
