Fix missing ETA during initial sync by reducing warmup period for clones

[Copilot]

ETA doesn't display during initial sync (git clone operations) until 3 repositories complete. Since clones take significantly longer than updates, users wait without feedback.

Changes

• Adaptive warmup period: Reduced from 3 to 1 repo for initial sync (clones), kept 3 for incremental sync (updates)

  • Detection: checks if s.cloned > 0 to determine sync type
  • Initial sync needs less warmup because each operation takes longer (more stable rate estimate)
  • Incremental sync keeps conservative warmup for accuracy with faster operations

• Progress calculation fix: Added s.archived to done count (was excluded, causing incorrect progress percentages)

Implementation

// Before: always required 3 samples
minSamples := min(10, s.totalRepos/10)
if minSamples < 3 {
    minSamples = 3
}

// After: adaptive based on sync type
minSamples := 1 // Start with 1 for initial sync
if s.cloned == 0 && done > 0 {
    // Incremental sync - more conservative
    minSamples = min(10, s.totalRepos/10)
    if minSamples < 3 {
        minSamples = 3
    }
}

Result: ETA appears after first clone completes instead of after third.

<agent_instructions>There's an ETA string that's supposed to show up when syncing, however at least on the INITIAL sync (eg. git clone/checkout) it does NOT appear at all and this needs to be fixed.</agent_instructions>
