Two concurrency bugs identified in PR #2904 review:
1. Replace sync.WaitGroup with sync.Cond-based activeReqCount to avoid
the "WaitGroup is reused before previous Wait has returned" panic that
occurs when Add(1) races with a goroutine-launched Wait().
2. Make panic cleanup conditional: when runTurn panics, only delete the
session's activeTurnStates entry if it still points to our placeholder.
Previously, an unconditional delete could wipe a new message's slot
claimed between the panic and the deferred cleanup.
* feat: add request-scoped context policies
Add named turn profiles under agents.defaults so callers can opt into
per-request context and tool policies without changing default chat behavior.
Profiles can disable history, system context, skill prompts, or tools, and can
limit skills/tools with allow lists. Wire profile selection through Pico message
payloads, agent turn execution, Web chat selection, and Web visual config.
Reject invalid turn profiles before saving config through Web APIs and document
the new request context policy behavior.
* fix: address turn profile review blockers
* feat: simplify request context policy config
* fix: suppress tool prompt when turn tools are disabled
* fix: enforce turn profile tool restrictions
* feat(chat,seahorse): persist and display model_name across history
* test(seahorse): fix lint regressions in repair coverage
* fix(pico): preserve model_name in live updates
* fix(pico): preserve model_name through live stream wrappers
* Support streaming
* fix: stream pico reasoning updates
Route Pico reasoning through the active streamer and hide empty thought placeholders.
* fix: harden configured streaming delivery
* fix ci
* fix split issue
- Use fmt.Sprintf fallback instead of {} on encoding errors
- Normalize nil args to {} in FormatArgsJSON for consistent output
- Update tests to expect {} instead of null for nil args
Based on PR #2670 review feedback from afjcjsbx
- Add PrettyPrint and DisableEscapeHTML config options to ToolFeedbackConfig
- Add FormatArgsJSON helper function with configurable pretty printing and HTML escaping
- Add toolFeedbackArgsPreviewWithOptions to pass formatting options
- Update pipeline_execute.go to use new formatting options for tool feedback
This fixes the issue where '&&' would be displayed as '\u0026' in tool
feedback messages and provides optional pretty-printing for better
readability.
