feat(coding-agent): support env vars and shell commands in headers

Header values in models.json now resolve using the same logic as apiKey:
- Environment variable names are resolved to their values
- Shell commands prefixed with ! are executed
- Literal values are used directly

This is a minor breaking change: if a header value accidentally matches
an env var name, it will now resolve to that env var's value.

Fixes #909

### Breaking Changes
- Header values in `models.json` now resolve environment variables (if a header value matches an env var name, the env var value is used). This may change behavior if a literal header value accidentally matches an env var name. ([#909](https://github.com/badlogic/pi-mono/issues/909))
- Resource loading now uses `ResourceLoader` only and settings.json uses arrays for extensions, skills, prompts, and themes ([#645](https://github.com/badlogic/pi-mono/issues/645))
- Removed `discoverAuthStorage` and `discoverModels` from the SDK. `AuthStorage` and `ModelRegistry` now default to `~/.pi/agent` paths unless you pass an `agentDir` ([#645](https://github.com/badlogic/pi-mono/issues/645))
### Added
- Header values in `models.json` now support environment variables and shell commands, matching `apiKey` resolution ([#909](https://github.com/badlogic/pi-mono/issues/909))
- `markdown.codeBlockIndent` setting to customize code block indentation in rendered output
- Extension package management with `pi install`, `pi remove`, `pi update`, and `pi list` commands ([#645](https://github.com/badlogic/pi-mono/issues/645))
- `/reload` command to reload extensions, skills, prompts, and themes ([#645](https://github.com/badlogic/pi-mono/issues/645))
