Adds four runnable read-only examples, each with helper-level tests, runner registration, validation exclusions, and README catalog entries. - 169-asset-holder-distribution (ISSUE-169): pages every trustline for an issued asset, aggregates supply statistics (total, average, median, largest), ranks holders, and reports configurable top-N concentration. Distinguishes authorized from unauthorized balances, counts zero-balance trustlines separately, and reports mid-stream pagination failures rather than presenting a partial set as complete. - 170-account-balance-liability-analysis (ISSUE-170): analyses balances, trustline limits, and buying/selling liabilities, deriving available amounts and limit headroom. Ledger-reported and derived values are kept visually separate. Flags near-limit trustlines and unauthorized lines. - 171-account-activity-profile (ISSUE-171): combines account metadata, transaction, operation, and payment history into one descriptive profile with fee aggregation and operation-type grouping. Each Horizon section records its own status so partial failures are reported instead of surfacing as silent zeros. - 172-horizon-request-tracing (ISSUE-172): a reusable tracing wrapper recording per-request timing, HTTP status, attempt counts, and slow-request detection, with min/max/average/median latency aggregation. Diagnostics are sanitized (secret seeds, JWTs, token query params) before logging. Also repairs three files left syntactically broken by the merge in #253, which prevented the project from typechecking on main: - src/runner/catalog.ts: restored the missing brace on the 192 entry and un-swapped the params blocks of entries 67 and 192. - src/validation/validation.config.json: restored the object boundary between the 192 and 66 exclusions, which made the file invalid JSON. Verified: all four examples run against Horizon Testnet in both text and JSON modes; 103 new tests pass; no new typecheck or lint errors.
