Changes Overview

This PR adds:

• Bluetooth audio documentation and configuration
• New pre-commit config and justfile for developer experience
• Minor fixes to I2C and CAN bus documentation

---

Issues Found

1. Missing text in Bluetooth Audio playback step

File: src/content/docs/operating-system/multimedia.mdx:259-260

Before you can play audio from your phone, you will need to enable 
Play an audio file on your phone, and will be streamed to the `bt-sink` profile in ALSA.

The sentence is incomplete. It seems like there should be instructions about enabling BlueALSA or starting the audio service before playing.

2. Clarification needed on unrelated documentation changes

The following changes appear unrelated to the Bluetooth audio feature:

• I2C.mdx (line 151): Changed RTC address from 0x68 to 0x51 — was this intentional?
• can-bus.mdx (lines 165-166): Changed CAN baud rate update command from spidev_test to vip can-baud — was this intentional?

The existing PR comment already flags this. Please confirm if these are related fixes or should be reverted.

Suggestions

1. Complete the incomplete sentence in the "Play Audio" section
2. Consider splitting unrelated changes (I2C and CAN bus fixes) into separate PRs for clarity

---

What looks good

• Comprehensive Bluetooth pairing instructions in connectivity.mdx
• Well-structured step-by-step guides using the <Steps> component
• Added ALSA configuration for Bluetooth sink (bt-sink)
• New developer tooling files (pre-commit, justfile)

---

Verdict

Once the incomplete sentence is fixed and the unrelated I2C/CAN changes are clarified, this PR will be ready to merge.

@brent-sink the edits to the CAN bus and I2C pages were intentional? Just double checking

[Pertempto]

Just a few suggestions. Looks like you already applied some before I finished 😅

[brent-sink]

Yes, the edits to can bus and i2c were intentional. The old rtc chip was obsoleted, so we're using a new one now and it has a different i2c address.
