- Add printf %q command escaping to run_server/interactive_session in
Koyeb, Render, Railway, and GitHub Codespaces (matching pattern used
by E2B, Daytona, Northflank, Fly, and other providers)
- Use json_escape in exchange_oauth_code to prevent JSON injection via
crafted OAuth codes in shared/common.sh
- Use json_escape in Fly.io _fly_create_app to prevent JSON injection
via FLY_ORG env var, plus add validation for org slug format
- Pass Fly.io _fly_create_machine values via env vars instead of Python
string interpolation to prevent code injection

Replace unsafe printf '%q'-escaped unquoted variables with validated
single-quoted embedding in upload_file() for fly, northflank, daytona,
e2b, and koyeb. The previous pattern used unquoted $escaped_content and
$escaped_path in command strings passed to bash -c or run_server, which
could allow command injection via crafted filenames.
The fix:
- Validates remote_path rejects unsafe chars (', $, `, newlines)
- Uses base64 content directly (alphanumeric + /+= is shell-safe)
- Single-quotes both content and path in the command string
- Uses printf '%s' instead of echo for safer output
Matches the pattern already used by render, modal, and railway.

- Split _fly_create_and_start_machine (70 lines) into _fly_create_machine
and _fly_wait_for_machine_start for single-responsibility
- Replace ensure_koyeb_token (38 lines) with ensure_api_token_with_provider
- Replace ensure_railway_token (37 lines) with ensure_api_token_with_provider
- Remove _save_koyeb_token and _save_railway_token (handled by shared helper)
Net reduction: ~80 lines of duplicated code

Railway: Missing base64 -w0 caused newline injection; unescaped remote_path
in single quotes allowed single-quote breakout command injection. Now uses
base64 -w0 with macOS fallback, printf '%q' for path escaping, and routes
through run_server instead of direct railway run bash -c.
Modal: Remote path was embedded in single quotes without escaping, allowing
single-quote breakout. Now uses printf '%q' for safe path escaping.
Koyeb: Used fragile deny-list validation for remote_path (rejecting specific
characters) and base64 without -w0 flag. Replaced with printf '%q' escaping
and added base64 -w0 with macOS fallback.

Koyeb's inject_env_vars used sed escaping that didn't handle single quotes,
allowing API key values containing ' to break out of the shell command string
passed to `koyeb instances exec`. Replace with file-based injection using
generate_env_config + upload_file, matching the safe pattern in shared/common.sh.
Hyperstack goose/gemini/interpreter/codex scripts embedded $OPENROUTER_API_KEY
directly in double-quoted command strings passed to run_server (SSH). Values
containing double quotes, backticks, or $() could execute arbitrary commands
on the remote VM. Replace with inject_env_vars_ssh which writes env vars to a
temp file, uploads via SCP, and appends to shell config without interpolation.
Also hardens Koyeb upload_file to reject remote paths containing shell
metacharacters (', $, `, newline).
