Benson Wong 75fced579e config: support macros in peer apiKey and filters (#469)
* config: support environment variable macros in peer apiKeys

Add ${env.VAR_NAME} substitution for peer apiKey fields, consistent
with existing env macro support for model fields and global apiKeys.

- Add env macro substitution for peers.{name}.apiKey in LoadConfigFromReader
- Add tests for peer apiKey env substitution
- Update config.example.yaml to show env macro usage

* config: support macros in peer apiKey and filters

Extend macro substitution to peer configuration fields:
- peers.{name}.apiKey supports both global macros and env macros
- peers.{name}.filters.stripParams supports both macro types
- peers.{name}.filters.setParams supports both macro types

Also renamed validateMetadataForUnknownMacros to validateNestedForUnknownMacros
for reuse across model metadata and peer filters validation.

Benson Wong 8f2137c72b config: support environment variable macros in apiKeys (#467)

allowing API keys to be loaded from environment variables using
the ${env.VAR_NAME} syntax.

- Apply env macro substitution before validation
- Add tests for env macro substitution in apiKeys

Benson Wong 124007cc98 config: add environment variable macros (#466)
* config: add environment variable macros

Add support for ${env.VAR_NAME} syntax to pull values from system
environment variables during config loading.

- env macros processed before regular macros (allows macros to reference env vars)
- works in cmd, cmdStop, proxy, checkEndpoint, filters.stripParams, metadata
- returns error if env var is not set
- add comprehensive tests

fixes #462

* docs: add env macro example to config.example.yaml

Benson Wong eb5bfff0b0 proxy: unify filtering for local models and peers
This unifies the filtering capabilities for models and peers

- stripParams: removes params in the request
- setParams: sets params in the request

Benson Wong 22e098ac8b Add Peer Model Support (#438)
This PR allows a single llama-swap to be the central proxy for models served by other inference servers. The peer servers can be another llama-swap or any API that supports the /v1/* inference endpoint.

Updates: #433, #299
Closes: #296

Benson Wong 53b32f3601 proxy: add API key support (#436)
Add configuration support for api keys that are enforced by llama-swap. Keys are stripped before sending them to upstream servers. 

Updates: #433, #50 and #251

Benson Wong 565c44766d config,proxy: add new configuration logToStdout (#432)
The new logToStdout option controls what is logged to stdout. The
default has been changed to just the proxy logs, which contain swap and
http request logs.

There are four supported settings: none, proxy, upstream, both. The
"both" setting is the legacy setting where everything was spewed to
stdout.

Benson Wong a89b803d4a Stream loading state when swapping models (#371)
Swapping models can take a long time and leave a lot of silence while the model is loading. Rather than silently load the model in the background, this PR allows llama-swap to send status updates in the reasoning_content of a streaming chat response.

Fixes: #366

Benson Wong 00b738cd0f Add Macro-In-Macro Support (#337)
Add full macro-in-macro support so any user defined macro can contain another one as long as it was previously declared in the configuration file.

Fixes #336
Supercedes #335

Benson Wong 70930e4e91 proxy: add support for user defined metadata in model configs (#333)
Changes: 

- add Metadata key to ModelConfig
- include metadata in /v1/models under meta.llamaswap key
- add recursive macro substitution into Metadata
- change macros at global and model level to be any scalar type

Note: 

This is the first mostly AI generated change to llama-swap. See #333 for notes about the workflow and approach to AI going forward.

Benson Wong 1f6179110c proxy/config: add model level macros (#330)
* proxy/config: add model level macros

Add macros to model configuration. Model macros override macros that are
defined at the global configuration level. They follow the same naming
and value rules as the global macros.

* proxy/config: fix bug with macro reserved name checking

The PORT reserved name was not properly checked

* proxy/config: add tests around model.filters.stripParams

- add check that model.filters.stripParams has no invalid macros
- renamed strip_params to stripParams for camel case consistency
- add legacy code compatibility so  model.filters.strip_params continues to work

* proxy/config: add duplicate removal to model.filters.stripParams

* clean up some doc nits

Benson Wong 216c40b951 proxy/config: create config package and migrate configuration (#329)
* proxy/config: create config package and migrate configuration

The configuration is become more complex as llama-swap adds more
advanced features. This commit moves config to its own package so it can
be developed independently of the proxy package.

Additionally, enforcing a public API for a configuration will allow
downstream usage to be more decoupled.
