Adds parser and tests for the EFP2 BOUTSTOP command, which cancels a
previously sent DISP and clears the bout on the given piste.

Adds parser and tests for the EFP2 TEAM command, which transfers the
list of team members for one side on a piste. Parses 4 members (3 active
+ reserve), 9 round fencer assignments, and a unique team ID.

Adds parsers and tests for the remaining simple EFP2 commands:
- NEXT/PREV: referee requests next/previous match (1 param: piste)
- STANDBY: switch apparatus to sleep mode (1 param: piste)
- BROKEN: report lost contact with piste (1 param: piste)
- UPDATED: notify clients that competition XML data has changed (2 params: eventId, competitionCode)

Adds parser and tests for the EFP2 INFO command, the primary piste state
message. Parses 42 tokens covering bout metadata (piste, event, phase,
round, state, stopwatch), referee flags (remote control, priority, calls
for technician/video/doctor/DT, reverse, standby), and full scoring data
for both fencers (id, name, nation, score, cards, lamps, video reviews).

Completes the full EFP2 command set:
- ACK/NAK: zero-param bout result acknowledgements from server to master
- GETTEAM: request team list from Server of Results (piste, side)
- DENY: rejection response with reason string

Adds round-trip tests for all 18 EFP2 commands through process(),
an unknown command test, fixes three mislabelled test names ('ping'
was used for STOP and MSG), and removes the stale skipped DISP test
that referenced an outdated output shape.

…f-concept)

Introduces a symmetric build/compose architecture that mirrors the existing
parse/process pipeline. `build()` returns a token array, `registerBuilder()`
registers it per command, and `compose()` at the protocol layer assembles the
full |EFP2|COMMAND|...| wire string. Round-trip tests verify parse→compose
fidelity for HELLO with and without a piste code.

Adds build() and registerBuilder() to all remaining 17 commands, registers
every builder in commands/index.js, and adds #registerBuilder + #build unit
tests to each command file. Protocol-level round-trip tests (compose ∘ process)
are added for all 18 commands in cyrano.test.js.

Test count grows from 195 → 246 passing.

Two UDP actors on loopback — Server (port 50100) and Master/piste RED
(port 50101) — walk through the complete lifecycle specified in the EFP2
protocol: HELLO → DISP → INFO(Not active) → INFO(Fencing) ×8 →
INFO(Ending) → ACK → INFO(Not active). The wire bytes logged at each
step are produced by compose() and consumed by process().
