Ctrl In Perf 1.0.0-experimental for Analog Rytm MKII (OS 1.74)

MrScruff's rytm-mods 0017-ctrl-in-perf, from rytm-mods-src (cd4ded4), ported from OS 1.73 to OS 1.74 and core-ar2 0.7. GLOBAL > CONTROL > CONTROL INPUT 1 and 2 get a PERF DEST row in CV and EXPR modes (OFF, PF1..PF12): the jack then sets that performance macro as its knob would, its locks follow, and it wins over the knob and pad. Category system, core-ar2 0.7, no dependency on another module, 1 site, 952 bytes of mod RAM.

What changed from the original (upstream/README.md): its audio-interrupt detour is replaced by ev_render_in, which runs before stock's macro smoother and lock loop in the same block; PERF DEST moves from a persisted RAM gap into two 4-bit global mod storage fields, saved with the globals slot; MODE is read through stock's settings getter on ev_tick. The CONTROL INPUT menu site is the original's, at its OS 1.74 address.

What this adds: sdk/analog-rytm-mkii/modules/ctrl-in-perf/ (source, build.json, manifest, README, TESTING, licence, thumbnail, two emulator screenshots with capture record), release notes, the import records and the source-only package sdk/imports/packages/ctrl-in-perf/ctrl-in-perf-1.0.0-experimental-os1.74.elemod (13ba8dff…c87b).

Checked: every OS 1.74 address read against the 1.73 original in Ghidra. Modwerk's linker on stock 1.74 with the Modwerk base for core-ar2 0.7 (plain variant ba530f45, build CP02, f154018e…08b9): the site's guard matches, and the module takes 672 bytes of flash and 952 of mod RAM. In analog-emu (4c07ed3): PERF DEST is the last row in CV and EXPR, steps OFF..PF12 and stops at both ends, and MODE OFF hides it; with PF1 set, a poked CV at ZERO, midway and MAX set macro 1 to 0, 63 and 127. Emulator results only. The pinned toolchain (build-elemod-isolated.sh, verify-elemod-release-exports.mjs) reproduces the committed package. npm run pr:ready says Ready.

Hardware (T208, 2026-11-08): on an Analog Rytm MKII, OS 1.74, a scripted run of CPH2 (CP02 plus the analoghealth remote-key layer, 3039fb3d…a954): PERF DEST is the last row in CV mode, steps OFF..PF12 and holds at both ends, MODE OFF hides it, and PF1 was kept over a project save, reload and a power cycle by hand. CPU 74.6% and 74.8%, heap flat. Stock 1.74 restored. The author listened to the unit throughout the run. Evidence tier author-hardware.

Not run on the unit: a CV source or expression pedal driving a macro (the jack had nothing plugged in, so that path is shown in the emulator only), EXPR mode and CONTROL INPUT 2. TESTING.md lists them.

What the guides lacked: the Rytm SDK README doesn't say that rytm-mods-src targets OS 1.73, so a direct port needs every address moved to 1.74. That goes in a separate Docs: PR.
