chore(publish): Remove lerna

[Tobbe]

lerna is only used for publishing Canarys and RCs. It's a heavy dependency that pulls in a bunch of deprecated deps. Getting rid of it to clean things up.

Greptile Summary

This PR removes lerna from the repository, replacing its canary and RC publishing workflows with direct npm publish calls and manual version calculation via git describe --abbrev=0 --tags + commit count.

• Canary publishing (publish_canary.sh) is fully rewritten in bash using yarn workspaces list, jq, and npm publish directly — no lerna involved.
• RC publishing (publish-release-candidate.mts) drops the lerna dry-run trick for version calculation in favour of explicit semver arithmetic from the latest git tag; publishPackages now re-throws on failure.
• Supporting cleanup: lerna.json is deleted, lerna is removed from devDependencies, the findUp('lerna.json') test anchor is updated to nx.json, and a new tasks/update-package-versions.cjs helper is added for stable-release version bumps.

The project overview doc (docs/implementation-docs/2026-03-26-cedarjs-project-overview.md) contains no references to lerna and accurately describes Nx as the build orchestration tool — no update needed there.

Confidence Score: 5/5

Safe to merge — the change is a clean dependency removal with equivalent functionality implemented directly in bash and TypeScript.

All publishing logic is a straightforward replacement of lerna commands with direct npm calls. The version calculation is deterministic using the existing git-tag strategy. The only finding is a minor argument-guard ordering issue in the new utility script.

No files require special attention; tasks/update-package-versions.cjs has a minor guard ordering nit but is otherwise correct.

Important Files Changed

Filename	Overview
.github/scripts/publish-release-candidate.mts	Replaced lerna-based version calculation and publish with direct git describe + commit count + npm publish. Errors in publishPackages now correctly re-throw.
.github/scripts/publish_canary.sh	Full rewrite from lerna-based canary publish to direct npm publish with manual version calculation via git tags.
tasks/update-package-versions.cjs	New utility script for updating workspace package versions. The argument-missing guard is unreachable because .replace() would throw a TypeError first.
packages/cli/src/commands/setup/graphql/features/fragments/codemod_tests/appGqlConfigTransform.test.ts	Updated findUp anchor from deleted lerna.json to nx.json — correct fix.
package.json	Removed lerna from devDependencies and dropped related minimatch overrides.
lerna.json	File deleted as part of the lerna removal.
