Closes #984
Closes #989

Issue #984 — Add read-only capabilities() view for recovery

• Declare pub mod capabilities in lib.rs (was missing, causing unresolved path)
• Enable recovery_tests and capability_bitmap_tests modules in lib.rs
• capability_bitmap_tests.rs: 12 end-to-end tests for capabilities() entrypoint including RECOVERY bit (bit 17), side-effect-free property, full bitmap match, reserved-bit guard, uniqueness, and range checks
• recovery_tests.rs: 12 tests covering validate_market_state_integrity, recover_market_state, partial_refund_mechanism, get_recovery_status, and end-to-end workflow; each verifies capabilities() advertises RECOVERY
• docs/CAPABILITIES.md: add Recovery Capability section with entrypoint table, workflow diagram, security properties, and test references

Issue #989 — Add storage-tier documentation

• storage.rs DataKey enum: add 10 missing variants that were referenced by subsystems but absent (OracleAdminCooldownState, MultisigRotationState, CollusionDetectorConfig, AdminOverrideNonce, PerLedgerBetCap, PerLedgerBetCounter, EventNonce, MarketAuditHead, MarketAuditLog, DeprecatedRegistry) each with inline tier rationale
• storage_tier_audit.rs: rewrite with accurate 37-entry audit table covering every DataKey variant and non-DataKey composite key, organised by subsystem; add 8 focused tests (coverage, purity, tier correctness)
• docs/STORAGE_TIER.md: full rewrite with per-subsystem key matrix, TTL tier definitions, tier-selection guide, and source references
