chore: use Bun package management and Turbo remote caching (#6978)

* feat: migrate tooling and runtimes to bun

* fix: serialize act installs and adapt backup checks

* fix: finish bun scripts and rootless act setup

* fix: support bun images in runtime benchmarks

* fix: keep a single bun toolchain configuration

* fix: include docs mascot sources in workshop build

* docs: use bun in remaining tool commands

* fix: complete bun sqlite development tooling

* docs: explain sqlite development adapter

* fix: align remaining commands and local ci validation

* fix: use renovate regex fallback with bun

* fix: finalize bun sqlite connections during cleanup

* fix: preserve sqlite foreign key enforcement

* fix: align docker build frontends

* fix: prepare release versions with bun

* Add Bun benchmarks and preserve SQLite connection defaults

* Benchmark Bun installs, conflicts and production workloads

* Force Bun workspace tools and HTTP/1.1 upstream streaming

* Exclude benchmark evidence from Docker contexts

* Expose branch benchmarks through CI

* Verify hydrated widget data in production benchmarks

* Measure image archives and document benchmark protocol

* Audit dependency sharing across every workspace

* Pin pnpm for nested baseline benchmark scripts

* Preserve nested manager pinning on benchmark resume

* Include application and runtime image footprints

* Fail benchmark gates on candidate command errors

* Report complete build overhead and sampled memory bounds

* Validate migration comparisons across pinned revisions

* Record configurable runtime memory budgets

* Retain out-of-memory kills in runtime budget probes

* Reject OOM events consistently across runtime metrics

* Record complete Bun migration benchmarks

* Record memory diagnosis and correct Turbo caching

* Use Bun package management while preserving Node runtimes

* Keep native build fallbacks and exclude development artifacts

* Fix Node ESM metadata and isolate local CI configuration

* Measure development performance and isolate act environment

* Support isolated environment files in rootless act

* Validate the full migration range with act

* Preserve native SQLite binding for bundled migrations

* Use documented dev defaults and report benchmark scope

* Validate dev defaults and isolate restart measurements

* Record package-manager and development benchmarks

* Keep benchmark measurements and link full command artifacts

* Clean up temporary act environment files

* Validate Node runtimes in package-manager comparisons

* Validate every workspace in manual CI runs

* Retain patched nested brace expansion versions

* Complete package-manager and Node performance report

* Normalize archived benchmark logs

* Record final hosted validation

* Cache both Next builds with platform isolation

* Prime cache with write-only mode

* Split Next artifacts below Cloudflare upload limit

* Assemble coherent standalone cache outputs

* Preserve traced middleware entrypoints

* Assemble traced directory links before files

* Separate cached dependencies from assembled output

* Record signed Turbo cache benchmarks

* Remove archived benchmark captures

Full benchmark evidence is preserved at 8f7d3bcd14109bfb13fa664d31710b88d820ad66.

* Remove migration benchmark harness

* fix: correct migration launch and local Act prerequisites

* Consolidate Turbo caches and production artifacts

* Exclude generated files from Docker cache inputs

* fix: address Bun migration review findings

* fix: check restored compiler bundle manifests
