feat(uno-q): bundle the granular skill set alongside arduino-uno-q on every node

Vendors the fork's 11 granular UNO Q skills (bridge, flashing, led-matrix,
uno-q-hardware, sketch-patterns, modulino, linux-led, audio, vision, wireless,
arduino-app-lab) next to the comprehensive arduino-uno-q skill, and installs the
whole set into every agent's workspace on each board.

Why both: the comprehensive skill is the rich cloud reference (read_skill →
references); the granular skills are keyword-triggered and match the fork's eager
skill-inliner rules, so the on-board Qwen auto-inlines them (no read_skill
round-trip). flashing + led-matrix carry the exact uno_q_flash + frame-API /
ArduinoGraphics-not-installed detail that makes flashing reliable.

- push-skill.sh generalized: a single skill dir (has SKILL.md) OR a parent dir
  installs every skill under it; provision-fleet now ships all of skills/.
- Verified on board 65301572: cloud/Sonnet-5 lists all 12 skills.

+description: How to compile and flash sketches to the Arduino Uno Q MCU over SWD using the uno_q_flash tool. Load this whenever the user asks to upload, flash, run, program, or build a sketch on the Uno Q.
+---
+
+# Flashing the Uno Q MCU
+
+Use the **`uno_q_flash`** tool. The MPU programs the MCU's flash directly over
+SWD (bit-banged GPIO via OpenOCD `linuxgpiod`) — no USB cable, no SSH.
+
+## How to use it
+
+- `action = "upload"` + `code` (full `.ino`) — compile then flash. The sketch
+  runs immediately (`reset run`). **This is what you call to make a sketch run.**
+- `action = "compile"` + `code` — verify it builds, don't flash.
+- `action = "detect"` — list boards.
+
+When the user asks to upload/flash/run a sketch, CALL the tool with
+`action="upload"`. Do not explain the steps in prose. Always provide the
+complete sketch (`setup()` + `loop()`).
+
+## Under the hood (for context, not for the user)
+
+- Compile: `arduino-cli compile --fqbn arduino:zephyr:unoq --export-binaries`.
+- Flash: OpenOCD writes the image to the bank-2 partition at **`0x8100000`**
+  (the correct sketch address; `0x80F0000` is reserved and never executes).
+- Requires on-device `arduino-cli` and `/opt/openocd` with `openocd_gpiod.cfg`.
+
+## If it fails
+
+- Compile errors come back in the tool result — fix the sketch and retry.
+- "OpenOCD not found" → the Zephyr core's OpenOCD isn't installed at `/opt/openocd`.
+- Remember the 3.3 V rule and that PWM is only D3/D5/D6/D9/D10/D11.
