Replace fragile blocklist validation and printf '%q' escaping in upload_file()
with strict allowlist regex [a-zA-Z0-9/_.~-]+ across all non-SSH cloud providers.
For codesandbox, additionally migrate from shell command interpolation to SDK
filesystem API via environment variables, eliminating the injection surface entirely.
Affected clouds: codesandbox, daytona, e2b, fly, koyeb, modal, northflank,
railway, render, sprite

- Fix macOS compatibility bug in Atlantic.Net API signature: `base64 -w 0`
fails on macOS (no `-w` flag); add fallback like other providers
- Replace misleading "Use 'csb' CLI dashboard" in CodeSandbox interactive
session with link to the actual web terminal at codesandbox.io/dashboard
- Soften preflight credential check prompt from "will likely fail" to
"will prompt you to authenticate" (scripts have built-in auth flows)
- Bump CLI version to 0.2.72

The file had 5 nearly-identical inline Node.js scripts, each repeating
the same require/init/async-IIFE/try-catch boilerplate. Extract two
shared helpers:
- _csb_sdk_eval: runs arbitrary JS with an authenticated SDK instance
- _csb_run_cmd: connects to a sandbox and runs a command (used by
run_server and interactive_session)
interactive_session was a verbatim copy of run_server — it now delegates
to run_server directly.
Net result: -96 lines, +49 lines (287 → 241 lines total).

Replace technical "Remediation steps:" with "How to fix:" and
"Remediation: Check <url>" with "Check your dashboard: <url>" across
14 cloud providers for clearer error guidance. Add actionable error
messages to Atlantic.Net create_server and SSH key registration failures.

Add CodeSandbox as a new sandbox cloud provider for running AI agents.
CodeSandbox features:
- Firecracker microVMs with ~2 second start times
- SDK/CLI-based exec (no SSH)
- Free tier: 40 hours/month on Build plan
- Secure isolated environments
Implementation:
- Created codesandbox/lib/common.sh with SDK wrapper functions
- Implemented 3 agent scripts: claude, aider, openclaw
- Added CodeSandbox to manifest.json clouds
- Created matrix entries (3 implemented, 12 missing)
- Updated test/record.sh to list as non-recordable CLI cloud
- Added codesandbox/README.md with usage instructions
The implementation follows the existing pattern from e2b and modal,
using Node.js SDK (@codesandbox/sdk) for sandbox lifecycle management.
