feat: add durable alpha-v2 orchestration kernel

[kmosoti]

Summary

• Add a host-authoritative alpha-v2 plan compiler and orchestration kernel with immutable plan versions, policy-bound execution, durable replay and checkpoints, bounded repair/replan/escalation, cancellation and budget fences, and content-addressed verification evidence.
• Feed generated plans through the existing /api/alpha/v1 daemon and worker authority; add authenticated RFC 10008 QUERY run discovery, a four-pane TUI projection, metadata-only OTel correlation, and typed Praxis promotion candidates.
• Add the proposal-only AGY 1.1.7 adapter and upgrade the Kernform boundary to 0.2.0 / kernform.command/v2 with closed compile, check, and init contracts.
• Update alpha plans, documentation, request templates, tests, and deterministic runtime-v1 SBOM and verification evidence without adding a dependency.

Verification

The committed .agent-worklog.json records:

• Publication-focused alpha-v2 surface: 69 tests passed.
• Maintained repository gate: 1,596 tests passed, with 2 declared environment-gated skips and 86.07% branch coverage against the unchanged 86% requirement.
• Rootless Podman acceptance passed, and all 81 configured telemetry mutants were killed.
• ruff check ., ruff format --check ., ty check, and git diff --check passed.
• Runtime-v1 evidence was regenerated and tools/release_evidence.py verify passed.

Known boundaries

• An in-flight provider subprocess cannot be force-cancelled; cancellation and deadline fences prevent subsequent effects.
• AGY 1.1.7 does not expose exact token or monetary usage, so those values remain explicitly unknown.
• No live Codex or AGY provider call was part of the publication gate; both proposal-only adapters were covered deterministically.
• Praxis output is a typed promotion candidate only and performs no external ledger write.
• Fourteen existing non-failing SQLite ResourceWarning reports remain technical debt.
