/**
 * Compact-CSV parser — reads the per-pattern boolean compact control file
 * that `compactReceiver` JS writes and `commitment_report` reads back to
 * attribute compacted bytes.
 *
 * Counterpart to `compact-csv-writer.ts`. The rate cap CSV uses a different
 * format (numeric bytes::reason:action, container-keyed) and is parsed by
 * `cap-csv-parser.ts`. This parser is for the compact CSV only.
 *
 * Row format: `<pattern_hash>,<true|false>:<untilEpoch>:<reason>`
 * Header: `fieldSet,value`
 *
 * Tolerances:
 *   - Blank lines and CRLF endings are skipped.
 *   - `#` comment lines are skipped.
 *   - Header line (`fieldSet,value`) is skipped.
 *   - Value may be just `true`|`false` (no epoch, no reason).
 *   - Value may be `true::<reason>` (no epoch, reason present).
 *   - Unrecognised boolean token → row pushed to malformed_lines.
