[codex] Implement runtime memory alignment pipeline

[ruttydm]

What changed

This PR lands a broad runtime-memory alignment pass in OpenCompany.

It adds the new memory/runtime services and wiring for:

• context budgeting
• context pruning
• structured compaction planning
• compaction memory extraction
• prompt frame splitting
• tool-result deduplication
• oversized tool-output truncation
• conversation summary failure tracking

It also updates related agent/runtime jobs, provider gateways, config, docs, Lua docs, and tests, while removing obsolete planning/todo docs.

Why

OpenCompany has been moving toward the stronger runtime patterns already explored in KosmoKrator and prism-relay. This branch consolidates that work into product code and accompanying documentation so prompt construction, compaction, flushing, and tool-output handling are more explicit and easier to evolve.

Impact

• Better prompt hygiene and context-pressure handling in agent flows.
• More explicit memory budgeting and compaction behavior.
• New test coverage for several of the new runtime helpers.
• Significant docs cleanup and replacement of stale planning artifacts with architecture/alignment docs.

Validation

Focused test execution was attempted with vendor/bin/phpunit because the repo's Composer test script still points to php artisan test, which is not available in this app.

Failed checks:

• vendor/bin/phpunit tests/Unit/PromptFrameBuilderTest.php tests/Unit/ToolResultDeduplicatorTest.php tests/Unit/OutputTruncatorTest.php tests/Unit/ContextPrunerTest.php tests/Unit/PrismMessagesTest.php
  • 1 failure: Tests\\Unit\\PrismMessagesTest::test_from_laravel_messages_preserves_assistant_tool_calls_and_tool_results
• vendor/bin/phpunit tests/Feature/Services/Memory/ConversationCompactionServiceTest.php tests/Feature/Services/Memory/MemoryFlushServiceTest.php tests/Feature/Services/Memory/ModelContextRegistryTest.php tests/Feature/OpenCompanyAgentTest.php
  • 4 errors and 3 failures, including summary persistence assertions and Illuminate\\Support\\MultipleInstanceManager resolution errors through Promptable

Notes

This PR is intentionally opened as draft because the current branch does not have a passing focused test baseline yet.

Superseded by #6, which merges the runtime memory work together with the integration refactor and the dev-branch follow-up fixes.
