Lyra v0.4.1 — PHROT + TX SWR protection & drive cap

TX protection and a voice-processing parity feature on top of v0.4.0.

New

Phase Rotator (PHROT) (#109) — WDSP TXA all-pass speech processor that symmetrizes asymmetric voice waveforms, lowering peak-to-average ratio for more average talk power at the same ALC/peak ceiling. Settings → TX checkbox, default ON. Auto-disabled in digital modes (DIGU/DIGL) — phase rotation distorts FT8/FT4/RTTY, so the toggle is your voice-mode intent and Lyra switches it off for you in digital, back on in voice modes.
SWR protection (#169) — auto-cuts TX above a user SWR threshold (default 5:1), with false-trigger guards (blanking, fwd/rev power floors, dwell), a latch, and a PROT lamp on the TX panel. Optional Fold action steps drive down instead of a hard cut.
TX power limit / drive cap (#170a) — Max-TX-drive ceiling (1–100%) for low-drive amplifiers; clamps the operator slider, TUN, BandMemory, and TCI DRIVE alike.

Improved

TCI handshake + Network-tab settings polish (#172).
User Guide: new "SWR protection & TX power limiting" section, a Phase Rotator section (incl. PHROT with wide/ESSB 4–10 kHz audio), and CW documentation.
