refactor(persistence): delete legacy interface; rename PersistenceV2 -> Persistence (phase 3)
End-state of the snapshot-persistence refactor. The legacy 13-proc
Persistence interface and its noOpPersistence are gone; the 5-proc
snapshot-based interface (formerly PersistenceV2) takes their place under
the canonical name.

Source:
- sds/types/persistence.nim: replaced 13-proc contract with the 5-proc
  snapshot interface (saveChannelMeta, updateHistory, loadChannel,
  dropChannel, setRetrievalHint). noOpPersistence returns ok everywhere
  and an empty ChannelData on load.
- sds/types/persistence_v2.nim: removed.
- sds/types/reliability_manager.nim: dropped the second persistenceV2
  field; constructor takes a single `persistence: Persistence`.
- sds/sds_utils.nim: rm.persistenceV2.X -> rm.persistence.X; doc-comments
  updated.
- sds.nim: dropped the persistenceV2 parameter from newReliabilityManager.

Tests:
- tests/in_memory_persistence_v2.nim: removed; its content moved to...
- tests/in_memory_persistence.nim: replaces the old legacy mock with the
  snapshot adapter under the canonical filename. Same InMemoryStore
  shape so test assertions stay unchanged.
- tests/test_persistence.nim: ctor param renamed, suite name de-prefixed.

FFI smoke (`nimble libsdsDynamicMac`, refc/threads:on): builds clean.
All 4 test suites pass:
- test_bloom
- test_reliability
- test_persistence (17 V2 tests)
- test_snapshot_codec (13 codec round-trip tests)

# GitNexus — Code Intelligence
This project is indexed by GitNexus as **nim-sds** (1100 symbols, 1820 relationships, 66 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.
> If any GitNexus tool warns the index is stale, run `npx gitnexus analyze` in terminal first.
## Always Do
- **MUST run impact analysis before editing any symbol.** Before modifying a function, class, or method, run `gitnexus_impact({target: "symbolName", direction: "upstream"})` and report the blast radius (direct callers, affected processes, risk level) to the user.
- **MUST run `gitnexus_detect_changes()` before committing** to verify your changes only affect expected symbols and execution flows.
- **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
- When exploring unfamiliar code, use `gitnexus_query({query: "concept"})` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
- When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use `gitnexus_context({name: "symbolName"})`.
## Never Do
- NEVER edit a function, class, or method without first running `gitnexus_impact` on it.
- NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
- NEVER rename symbols with find-and-replace — use `gitnexus_rename` which understands the call graph.
- NEVER commit changes without running `gitnexus_detect_changes()` to check affected scope.
