Add context flags to TaskConfig

[luisorofino]

What does this PR do?

Adds two optional boolean flags to TaskConfig — clear_context_before and compact_context_before — that give flow authors explicit control over context management before a task runs. When clear_context_before is set, the agent's history is fully reset before the task. When compact_context_before is set, the context is compacted unconditionally, regardless of usage thresholds. Both flags take priority over the automatic compaction logic and are mutually exclusive (validated at config parse time).

Motivation

The existing automatic compaction only triggers when context usage crosses a threshold, which is not always the right behavior. Some tasks benefit from starting with a completely clean slate (e.g., independent subtasks that should not see prior work), while others benefit from a forced compaction regardless of how full the context is. These flags give flow authors the control they need without relying on heuristic-based auto-compaction.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add qa/required if this PR needs QA validation, or qa/skip-qa if it does not. Exactly one of the two is required.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
