Add CI, a test suite, and a deploy script
CI / verify (push) Failing after 34s

`npm test` did nothing until now. CI that runs no tests is theatre, so the
tests came first — 39 of them, over the two places where an error would be
silent and expensive.

packages/core: the margin arithmetic. Every dashboard figure, idle-capacity
alert and agent answer resolves through it, and wrong numbers still look like
numbers. The cases pin decisions rather than implementation: cost is charged
against the full commitment (a naive version reports the opposite sign on a
loss-making block), aggregation sums cents rather than averaging percentages
(averaging reports +22% on a book that is losing money), break-even prices the
remaining hours and returns null rather than Infinity when there are none, and
internal research burn counts as cost with no revenue.

packages/prime: the upstream mapping. Rounding rather than truncating cents,
because 2.43 is 2.4299999 in binary and a lost cent compounds across millions
of GPU-hours. And interconnect normalisation, where an unrecognised fabric maps
to Unknown rather than Ethernet — guessing low loses a deal, guessing high
sells a training customer a cluster that cannot train.

CI runs on push and pull request: typecheck all six packages, unit tests,
migrations applied twice to a real Postgres, a seed-idempotency assertion that
fails the build if row counts move on a second run, a server boot, the front-end
build, and a Docker build.

It also asserts the inline theme script's hash still matches the CSP the proxy
allows. That script prevents a white flash for dark-mode users; if it changes
without the CSP being updated, the browser silently blocks it and nothing
anywhere reports an error.

Deployment stays a script rather than push-to-deploy. Automating it would put
an SSH key with production write access on the CI runner — a real escalation
for a project this size. The script takes a database dump before migrating and
refuses to finish if an unauthenticated request returns anything but 401.

# Continuous integration.
#
# Runs on every push and pull request. The job is deliberately one sequence
# rather than a fan-out: this is a small project, the whole thing takes a
# couple of minutes, and a single log is easier to read than five.
#
# What it actually proves, in order of how likely each is to catch something:
#
# 1. Every package typechecks.
# 2. The migration chain applies to a REAL, empty Postgres. This has already
# caught one migration that Drizzle generated but Postgres refused
# (a jsonb -> integer cast with no USING clause).
# 3. The seed is idempotent — running it twice leaves the same row counts.
# This caught a seed that silently duplicated 27 contacts.
# 4. The unit tests pass.
# 5. The server boots against that database and answers.
# 6. The front end builds, and the CSP hash for the inline theme script still
# matches what the proxy is configured to allow. Editing that script
# changes its hash, and the failure mode is a silent white flash for
# dark-mode users rather than an error.
