Kyle Isom f5e67bd4aa Phase 4: policy engine with deny-wins, default-deny evaluation
internal/policy/:
Priority-based policy engine per ARCHITECTURE.md §4. Stateless
Evaluate() sorts rules by priority, collects all matches, deny-wins
over allow, default-deny if no match. Rule matching: all populated
fields ANDed, empty fields are wildcards, repository glob via
path.Match. Built-in defaults: admin wildcard (all actions), human
user content access (pull/push/delete/catalog), version check
(always accessible). Engine wrapper with sync.RWMutex-protected
cache, SetRules merges with defaults, Reload loads from RuleStore.

internal/db/:
LoadEnabledPolicyRules() parses rule_json column from policy_rules
table into []policy.Rule, filtered by enabled=1, ordered by priority.

internal/server/:
RequirePolicy middleware extracts claims from context, repo from chi
URL param, evaluates policy, returns OCI DENIED (403) on deny with
optional audit callback.

69 tests passing across all packages.
