More configurable timeout values in config.toml

[evilJazz]

Following my earlier PR #15 here is another change that removes more hard-coded timeout values from the code and moves them into the config.toml.
I also de-duplicated the duration parsing logic by moving it into a new reflection-driven helper function parseDurations that reads the existing toml and newly added default struct tags. All timeouts, intervals and durations have been moved into a composite struct ProxyConfig.Durations and the code has been refactored accordingly.

This fixes an issue in conjunction with my local llama-cpp instance when running very long LLM sessions where creating an answer by the LLM might take over 10 minutes (600 seconds). llama-cpp would always show "cancel task" in the log files, causing the output to be truncated and agent to re-iterate over and over again (and the advisor-LLM in omp to get "angry" LOL).

Thank you for this project! You are saving a lot of power keeping my space-heater server "Deepthought" powered down most of the time. :D

DELETED coderabbitai edit of my comment. This is an absolute NOGO.

Thanks for the PR — making these timeouts configurable is the right call, and the defaults matching the old hard-coded values keeps existing setups safe. A few asks before merging:

1. Replace the reflection-based parseDurations with plain explicit parsing (or a small parse(name, value, default) helper). The match-by-field-name contract between Config and Durations fails silently — a misspelled field name drops a duration to zero with no compile error and no test catching it. Explicit code is about as short and much safer here.

2. Formatting: the reflect import is unsorted (before crypto/tls), and the continuation line in the waitForWake timeout error lost its indentation. gofmt/goimports will fix both.

3. Document that "0" disables a timeout in the README — that's what you'll want for your >10-minute LLM responses, since the 10m default will still cut them off.

Happy to merge after that. Thanks again!

Walkthrough

The change adds four configurable HTTP server timeouts. LoadConfig parses these values with defaults and validation. The HTTP server uses the parsed durations instead of fixed values.

Changes

HTTP timeout configuration

Layer / File(s)	Summary
Timeout contracts and parsing config.toml, main.go	The configuration structs define four timeout fields. LoadConfig parses them with defaults and returns errors for invalid durations.
HTTP server timeout wiring main.go	The HTTP server uses the configured read, write, idle, and request-header timeout durations.

Full details: Tests

Explanation

The pull request adds configurable timeout parsing and HTTP server wiring, but it adds no test files or test changes. Existing tests do not reference the new timeout fields. The shipped-config test only checks that config.toml loads, and the duration test only covers the existing timeout. No test verifies custom values, defaults, invalid values, or that Start applies the values to http.Server.

Resolution

Add tests that load configurations with custom and omitted timeout settings and assert all four parsed durations and defaults. Add invalid-value cases for the new settings. Add a server-level test that verifies the configured durations are applied to ReadTimeout, WriteTimeout, IdleTimeout, and ReadHeaderTimeout, including the intended zero-value behavior if supported.

The existing LoadConfig tests do not establish coverage for the four new timeout fields. Add focused cases for omitted-value defaults, invalid-duration errors, explicit zero values, and assignment into ProxyConfig so regressions at this parsing boundary are detected before relying on these settings.

Document the five timeout keys and their zero-value behavior. config.toml exposes request_header_timeout, response_header_timeout, server_read_timeout, server_write_timeout, and server_idle_timeout, but the user-facing documentation describes only timeout. Operators cannot determine the default values or how zero values affect these settings. Add the five keys, their defaults, and their inheritance or disable semantics to the configuration documentation.
