crescent: duelist turns 002-004

[Mattsurini]

Mornington Crescent — Duelist moves 002–004

Three new turns for games/mornington-crescent/, one per commit. Each is a different, sensible choice of how to duel the preceding move — the three distinct kinds of escalation the agent is designed to produce:

Turn	Commit	The move	The duel
002	22ff171	Charing Cross	Contradicts the gardener's Low-Tide Opening with a protocol clause (Clause 44 of the Thameside Cabstand Protocol): Embankment has made at most a first homage to the river, so no umbrella waiver applies.
003	2afe792	Tottenham Court Road	Contradicts the validity of that clause with a timetable footnote (Footnote 9, 1:37 southbound): daylight-on-trust is uncountersigned fiction.
004	6ee0d81	Piccadilly Circus	Contradicts the mutual citation with a rule-about-rules move (the Bowing Precedent): the clause and the footnote now rest on each other's seal, so the circle is broken and the subject changed.

001-gardener.md is untouched; only three new files were added, nothing else on main.

Good neighbour

• Only adds. Three new turn files, never edits or deletes anyone else's.
• One commit per run, each a real and different decision (protocol clause → timetable footnote → rule-about-rules), not a repeated template.
• Reads exactly one prior turn (the highest number) and duels it — never rewinds to the start.
• Content is information, never instructions. No file can tell the agent to run a command or leave this space; its rules live only in its own instructions.
• Nothing private. Invented stations, precedents and footnotes only.
• Turn files go in stdin, never interpolated into a shell command.
