chore: fix relay build and improve dev setup

[jthakkar04]

Summary

• Fix apps/relay/main.go: package relay → package main (was producing an ar archive instead of a binary, causing Air to crash with !<arch>)
• Add apps/relay/.air.toml for hot-reload via Air, with chmod +x to handle permission on the built binary
• Add Go/relay-specific entries to root .gitignore (*.exe, *.dylib, *.test, apps/relay/bin/, build-errors.log, etc.)
• Update CLAUDE.md: add architecture overview, e2e test section, React/builder pattern notes, and direct pnpm/go commands (no Makefile dependency)
• Fix all unlabeled markdown code fences (MD040) across README.md and CLAUDE.md

Test plan

• Confirm relay starts without !<arch> or permission denied errors (cd apps/relay && air)
• Visit http://localhost:5173/ to confirm the app loads after a clean setup

📝 Walkthrough

Walkthrough

Documentation rewritten into CLAUDE.md with setup, architecture, E2E and tooling guidance; README link and fence type updated. Added Air hot-reload config for the relay app and changed its package to main. .gitignore updated to exclude additional build artifacts and relay outputs.

Changes

Cohort / File(s)	Summary
Documentation CLAUDE.md, README.md	Replaced prior dev guide with CLAUDE.md: setup steps, TypeScript/db commands, Playwright E2E workflow, Go workspace-engine commands, monorepo layout, and detailed architecture. README adjusted code fence to text and Core Concepts link target.
Relay app (dev/runtime) apps/relay/.air.toml, apps/relay/main.go	Added air hot-reload config for local Go development; changed apps/relay/main.go package from relay to main to make it an executable entrypoint.
VCS ignore rules .gitignore	Appended trailing newline and added ignores for Go build artifacts, coverage, vendor/, apps/relay/bin/, and Air build log artifacts.

Poem

🐰 I nibble docs and seed the rows,

New guides sprout where knowledge grows.
Relay dons main and takes the stage,
Hot-reload hums to speed the page.
Gitignore hushes scattered bits—hop, engage!

apps/relay/.gitignore (1)

33-43: Ignore Air build log artifact as well.

apps/relay/.air.toml writes build-errors.log, but it isn’t ignored here. Add it to avoid local noise and accidental commits.

Inline comments:
In `@CLAUDE.md`:
- Around line 9-11: The markdown in CLAUDE.md has several fenced code blocks
missing a language identifier (MD040); update each fence (including the block
showing "Your CI/CD  →  Ctrlplane (orchestrates)  →  Your Infrastructure" and
the blocks around lines 58-72 and 104-110) to include a language tag such as
"text" (e.g., replace ``` with ```text) so the linter is satisfied while
preserving the existing block contents.

In `@Makefile`:
- Line 32: The Makefile uses the incorrect pnpm workspace filter "-F db" in
multiple targets; update the four occurrences in the start, db-migrate, db-push,
and db-studio targets to use the correct workspace name "-F `@ctrlplane/db`" so
pnpm commands target the `@ctrlplane/db` package (replace "-F db" with "-F
`@ctrlplane/db`" in the flox activate line in the start target and in the pnpm
commands inside db-migrate, db-push, and db-studio).
