[angeloashmore]

Resolves:

Description

Align project infrastructure with prismic-typescript-template:

• Switch formatter from Prettier to oxfmt
• Consolidate CI workflows from 4 files (release.yml, prerelease-canary.yml, prerelease-pr.yml, prerelease-pr-cleanup.yml) into 2 (validate.yml, publish.yml)
• Update tsconfig.json with declarationMap, esModuleInterop, and other missing options
• Add $schema and prefer-const rule to .oxlintrc.json
• Update CONTRIBUTING.md to use Release Please publish flow and node --run commands
• Update bug report issue template

Note

Medium Risk
Mostly infrastructure/tooling churn (CI workflow consolidation, formatter swap, tsconfig tweaks) with low runtime impact, but it changes the npm publish/release automation and formatting rules across the repo, which could disrupt releases or CI if misconfigured.

Overview
Aligns repository infrastructure with the template by replacing Prettier with oxfmt (new .oxfmtrc.json, updated format script, dependency updates, and removal of Prettier config/ignore files) and tightening lint config ($schema + prefer-const in .oxlintrc.json).

Consolidates GitHub Actions publishing into a single publish.yml that handles Release Please releases plus canary/PR prereleases (and deprecation/cleanup), deleting the prior release.yml and prerelease workflows; validate.yml is also adjusted (e.g., MODE=production for builds).

Updates developer/docs ergonomics: tsconfig.json gains missing compiler options (e.g. declarationMap, esModuleInterop), CONTRIBUTING.md is updated to the Release Please flow and node --run commands, the bug report template wording/examples are refreshed, and a large set of source/e2e files are reformatted to match the new style (no semicolons/import sorting) with no intended behavior changes.
