fix: three runtime and logic bugs

[onthebigtree]

Summary

• selector.js: matchPatternToSignals was defined but missing from module.exports. evolve.js imports it at line 17 to filter hub candidates against current signals — any evolution cycle reaching that path threw TypeError: matchPatternToSignals is not a function.

• index.js: Initial value of currentSleepMs was computed as Math.min(maxSleepMs, Math.max(minSleepMs, minSleepMs)). The inner Math.max(minSleepMs, minSleepMs) always equals minSleepMs, reducing the expression to Math.min(maxSleepMs, minSleepMs). If EVOLVER_MAX_SLEEP_MS is misconfigured below EVOLVER_MIN_SLEEP_MS, the daemon starts with a sleep value below its own minimum — violating the invariant the rest of the loop maintains. Replaced with minSleepMs.

• solidify.js: checkConstraints used Math.max(Number(constraints.max_files) || 0, 20), silently raising any gene-defined max_files below 20 to 20. A built-in gene already uses max_files: 12 (line 780), which was ignored. Changed to only fall back to the default of 20 when no constraint is set.

• solidify.js / evolve.js (cleanup): Removed two redundant const declarations that shadowed identical outer-scope variables (sourceType in solidify.js, selectedBy in evolve.js). No behaviour change — outer variables carry the same value and are in scope.

Test plan

• Run an evolution cycle that triggers hub candidate filtering and confirm no TypeError from matchPatternToSignals
• Start daemon with EVOLVER_MAX_SLEEP_MS < EVOLVER_MIN_SLEEP_MS and confirm initial sleep respects the minimum
• Apply a gene with max_files: 5 and verify a 6-file patch is correctly flagged as a violation

Note

Low Risk
Small, localized runtime/logic fixes in the evolver loop, selector exports, and solidify constraint handling; low risk but affects scheduling and enforcement paths that are exercised frequently.

Overview
Fixes three runtime/logic issues affecting evolution cycles.

index.js now initializes the daemon loop sleep interval to minSleepMs (avoids starting below the configured minimum). src/gep/selector.js exports matchPatternToSignals to prevent runtime failures when filtering hub/external candidates. src/gep/solidify.js corrects max_files constraint handling to respect gene-defined limits below 20 instead of silently raising them to the default; plus minor cleanup removing redundant/shadowing locals in src/evolve.js and src/gep/solidify.js.
