tooling: Add Makefile for common development commands.

[nedseb]

Description

Unified developer tooling setup: Makefile as primary interface + npm for git hooks and release management.

Makefile targets

Run `make help` to see all available commands:

Command	Description
`make install`	Install pip + npm dependencies
`make prepare`	Install git hooks (husky)
`make setup`	Full dev setup (install + prepare)
`make lint` / `make lint-fix`	Ruff linter / auto-fix
`make test`	Mock tests (suggests test-all for hardware)
`make test-mock`	Mock tests only
`make test-hardware`	All hardware tests (needs board)
`make test-board`	Board tests (buttons, LEDs, buzzer)
`make test-sensors`	Sensor hardware tests (I2C)
`make test-all`	All tests (mock + hardware)
`make test-`	Per-scenario (e.g. `make test-hts221`)
`make test-examples`	Validate example files
`make ci`	Full CI pipeline (lint + tests + examples)
`make build`	Build (lint + test)
`make repl` / `make mount`	REPL / mount lib/
`make clean` / `make deepclean`	Caches / everything including node_modules

Per-scenario targets are generated dynamically from `tests/scenarios/*.yaml`.

Git hooks (npm + husky)

• commit-msg : commitlint (conventional commits, per-driver scopes, max 78 chars)
• pre-commit : validate-branch-name + git-precommit-checks + lint-staged (ruff)

npm scripts

Scripts delegate to make targets:

• `npm run build` → `make build`
• `npm run ci` → `make ci`
• `npm run setup` → `make setup`
• `npm run commit` → commitizen (interactive commit assistant)

Configuration files

File	Purpose
`Makefile`	Primary command interface
`env.mk`	Environment variables (PATH, PORT)
`package.json`	npm scripts + devDependencies
`commitlint.config.js`	Commit message rules
`.validate-branch-namerc.js`	Branch name patterns
`git-precommit-checks.config.js`	Pre-commit content checks
`.prettierrc.json`	Prettier (JS/JSON/YAML)
`.releaserc.json`	semantic-release
