feat!: v0.2.0 production hardening

[bntvllnt]

Summary

• Auth boundary: ownerId required on all admin mutations (revoke/disable/enable/update/rotate/getUsage) — prevents cross-tenant access
• Server-side secret gen: create() and rotate() generate secret material inside component mutations, no longer passed from client
• Remove apiKeyEvents table: structured logging replaces event-based audit trail — eliminates unbounded table growth, O(N) scans, retention cron complexity
• Remove @convex-dev/rate-limiter: rate limiting is integrator's responsibility at their HTTP layer where they have caller context (IP, auth, plan tier)
• Remove @convex-dev/aggregate + @convex-dev/crons: unused deps removed (component deps: 4 -> 1)
• Input validation: keyPrefix/env charset, gracePeriodMs min/max bounds, metadata/scopes/tags size caps, configure() bounds
• Validate optimization: remaining decrement and lastUsedAt write decoupled into single merged patch; lastUsedAt throttled to 60s
• Pagination: list()/listByTag() use .take(100) default limit instead of unbounded .collect()
• revokeByTag: now catches rotating + disabled statuses (not just active)

Breaking Changes

Change	Migration
create() args	Remove hash, lookupPrefix, secretHex — server generates internally
rotate() args	Remove lookupPrefix, secretHex — server generates internally
Admin mutations	Add ownerId as required arg
getUsage()	Remove period param, lastUsedAt from return
apiKeyEvents table	Export existing data before upgrading — table is removed
@convex-dev/rate-limiter	Add your own rate limiting at HTTP action layer
