Fix restart delay operator precedence and status KV write initialization

[Copilot]

Two bugs in process lifecycle management: restartDelayMs was silently ignored when watch was also configured, and application state was not persisted to KV store for the first 20 seconds after startup.

Operator precedence: restartDelayMs ignored when watch is set

?? has higher precedence than ?:, so the intended fallback expression was evaluated incorrectly:

// Was parsed as: (config.restartDelayMs ?? config.watch) ? 500 : 10000
const baseRestartDelay = config.restartDelayMs ?? config.watch ? 500 : 10000

// Fixed:
const baseRestartDelay = config.restartDelayMs ?? (config.watch ? 500 : 10000)

Any process with both restartDelayMs and watch configured would always restart with a 500ms delay regardless of the configured value.

Status KV write skipped for first 20 seconds

lastWrite was initialized to Date.now(), causing Date.now() - this.lastWrite > APPLICATION_STATE_WRITE_LIMIT_MS to be false on every watchdog tick until 20 seconds had elapsed. Changed initialization to 0 so the first write happens on the first watchdog tick. Also removed the now-unreachable if (!this.lastWrite) dead code block, and corrected the misleading docblock that claimed last_application_state was written on every iteration.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.deno.land
  • Triggering command: /usr/bin/curl curl -s REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
