docs(client): finish the five-state and Pill/Tag corrections

The `idle` addition left two maintainer-facing statements behind: the
README's limitations entry still listed four supported StateDot states,
and TerminalBlock's run-state JSDoc still counted the union as four while
correctly saying three of them are reachable there.

Pill's header comment still sent every capsule without `onClick` to Tag,
which contradicts both the catalog this pull request corrected and
TerminalBlock's own static read-only Pill two files away. Size separates
the two controls as much as interactivity does, and the comment now says
so. The function JSDoc and the static-mode tests stay as they are: they
describe supported behavior.

 - **Glyph-level icons are redrawn approximations** — the fish logo and the sparkle mark come from font glyphs whose vector geometry is not exportable from the local design data; hand-authored recreations stand in until an exact export path exists.

 - **`TerminalBlock` is not a terminal emulator** — it renders settled or still-running command output, not an interactive session: SGR colors, carriage return, backspace, erase-in-line, tab stops, and character width are honored; absolute cursor positioning, screen clearing, and alternate-screen sequences are stripped.
