Add configurable daemon HTTP bind address (--bind / config bind)

[Copilot]

The daemon HTTP listener was effectively locked to loopback (127.0.0.1), which prevented running it on 0.0.0.0 or other explicit interfaces. This change makes bind address configurable at runtime and in config, while preserving loopback as the default.

• CLI + config surface

  • Added --bind <addr> to oly daemon start.
  • Extended config overrides with bind (default remains 127.0.0.1).
  • Plumbed runtime overrides through daemon startup path.

• HTTP server binding behavior

  • Replaced hardcoded 127.0.0.1 socket construction with parsed http_bind + http_port.
  • Listener startup logs now render the effective URL from configured bind/port.
  • Detached start path now forwards bind override to internal foreground process.

• Daemon status/summary output

  • Detached/status HTTP summary now reports the configured bind address instead of always showing loopback.
  • URL formatting handles IPv4/IPv6 correctly.

• E2E and supporting test utilities

  • Added start_daemon_http_with_bind(...) in shared e2e helpers.
  • Added e2e coverage proving --bind 0.0.0.0 starts successfully and serves HTTP requests.

• Docs alignment

  • Updated CLI usage/docs to include --bind.
  • Updated HTTP behavior/spec text to reflect configurable bind address.

# New runtime behavior
oly daemon start --bind 0.0.0.0 --port 15443

Move the duplicate fn format_http_url to src\utils.rs.

Move the duplicate fn format_http_url to src\utils.rs.

Done in e62280c. I moved format_http_url into src/utils.rs and updated both call sites (src/http/mod.rs and src/daemon/lifecycle.rs) to use the shared helper.
