revert: back out IRR-AGL reliability/governance stack (#405, #416)

Reverts merge commits 0b867a7 (#405) and 474f5e4 (#416), and removes the
now-orphaned #406 artifact metadata store (src/reliability + tests, zero
references left outside its own tests).

Why: the stack wrapped the tool registry in every session path (even
governance mode=off) without exposing the registry surface AgentContext
reads, breaking all session-runtime chats within a day (#433, #431). It
also modified protected core files (src/agent/loop.py, src/session/
service.py), shipped 12 internal-convention docs/ files into the public
tree, and its enforcement layer already has reported bypass paths (#420).
Trading safety stays on the single mandate-gate design (#31, #144).

README news entries for 2026-07-07/07-06 updated accordingly.

-## IRR-AGL Contributor Boundaries
-
-IRR-AGL work must be additive and reviewable:
-
-- Prefer wrappers, adapters, audit extensions, and read-only surfaces.
-- Do not rewrite `AgentLoop`, `ToolRegistry`, loader registry, backtest engines,
-  MCP schemas, or live-safety gates for governance integration.
-- Preserve `BaseTool.execute(**kwargs) -> str`,
-  `ToolRegistry.execute(name, params) -> str`, and
-  `DataLoaderProtocol.fetch(codes, start_date, end_date, interval="1D", fields=None)`.
-- Keep `VIBE_TRADING_RELIABILITY_MODE=off` and
-  `VIBE_TRADING_GOVERNANCE_MODE=off` backward compatible.
-- New schemas need `schema_version`; new JSON hashes must be canonical.
-- Structured `warnings` and `hard_failures` should use stable codes, not only
-  free text.
-- Artifacts, traces, cards, and logs must pass secret redaction.
-- `R4_TRADE_WRITE` and `R5_SHELL` deny decisions must shadow-deny outside
-  `off`; do not let observe/warn execute high-risk denied tools.
-- Governance cannot approve live mandates and cannot replace
-  `LiveOrderGuardTool`.
-- DSR/PBO are experimental metrics only, not production pass gates.
