📚 docs: add missing READMEs and align crates with Rust rules

- Create README.md for paracas-daemon and paracas-estimate
- Add #![doc = include_str!("../README.md")] to daemon/estimate lib.rs
- Add missing Cargo.toml metadata (docs.rs, authors, keywords, categories)
- Reorder workspace dependencies by line length per style guide
- Document background jobs, download-all, status, and job commands

+# paracas-estimate
+
+Download size and time estimation for the paracas tick data downloader.
+
+## Features
+
+- Historical size estimates per instrument category
+- Download time estimation based on data volume
+- Confidence levels for estimates
+
+## Types
+
+- `EstimateDatabase` - Database of historical size estimates per category
+- `CategoryEstimate` - Size estimates for a single category
+- `Estimator` - Computes download estimates for instruments and date ranges
+- `DownloadEstimate` - Estimated download metrics
+- `EstimateConfidence` - Confidence level of the estimate
+
+## Usage
+
+```rust,ignore
+use paracas_estimate::{Estimator, EstimateDatabase};
+use paracas_types::{Category, DateRange};
+
+// Create an estimator with the default database
+let db = EstimateDatabase::default();
+let estimator = Estimator::new(&db);
+
+// Estimate download for a date range
+let range = DateRange::new(start, end)?;
+let estimate = estimator.estimate(Category::Forex, &range);
+
+println!("Estimated size: {} bytes", estimate.size_bytes);
+println!("Confidence: {:?}", estimate.confidence);
+```
