083e7d40ce refactor!: rename module to github.com/theirongolddev/cburn
Change module path from 'cburn' to 'github.com/theirongolddev/cburn'
to enable standard Go remote installation:

  go install github.com/theirongolddev/cburn@latest

This is a BREAKING CHANGE for any external code importing this module
(though as a CLI tool, this is unlikely to affect anyone).

All internal imports updated to use the new module path.

892f578565 fix: linter compliance and code quality improvements across codebase
Address golangci-lint findings and improve error handling throughout:

Package doc comments:
- Add canonical "// Package X ..." comments to source, model, config,
  pipeline, cli, store, and main packages for godoc compliance.

Security & correctness:
- Fix directory permissions 0o755 -> 0o750 in store/cache.go Open()
  (gosec G301: restrict group write on cache directory)
- Fix config.Save() to check encoder error before closing file, preventing
  silent data loss on encode failure
- Add //nolint:gosec annotations with justifications on intentional
  patterns (constructed file paths, manual bounds checking, config fields)
- Add //nolint:nilerr on intentional error-swallowing in scanner WalkDir
- Add //nolint:revive on stuttering type names (ModelStats, ModelUsage)
  that would break too many call sites to rename

Performance (perfsprint):
- Replace fmt.Sprintf("%d", n) with strconv.FormatInt(n, 10) in format.go
  FormatTokens() and FormatNumber() hot paths
- Clean up redundant fmt.Sprintf patterns in FormatCost and FormatDelta

Code cleanup:
- Convert if-else chain to switch in parser.go skipJSONString() for clarity
- Remove unused indexedResult struct from pipeline/loader.go
- Add deferred cache.Close() in pipeline/bench_test.go to prevent leaks
- Add deferred cache.Close() in cmd/root.go data loading path
- Fix doc comment alignment in scanner.go decodeProjectName
- Remove trailing blank line in cmd/costs.go
- Fix duplicate "/day" suffix in cmd/summary.go cost-per-day formatting
- Rename shadowed variable 'max' -> 'maxVal' in cli/render.go Sparkline

0e9091f56e feat: add SQLite cache store for incremental session persistence
Implement the caching layer that enables fast subsequent runs by
persisting parsed session data in SQLite:

- store/schema.go: DDL for three tables — sessions (primary metrics
  with file_mtime_ns/file_size for change detection), session_models
  (per-model breakdown, FK cascade on delete), and file_tracker
  (path -> mtime+size mapping for cache invalidation). Indexes on
  start_time and project for efficient time-range and filter queries.

- store/cache.go: Cache struct wrapping database/sql with WAL mode
  and synchronous=normal for concurrent read safety and write
  performance. Key operations:

  * Open: creates the cache directory, opens/creates the database,
    and ensures the schema is applied (idempotent via IF NOT EXISTS).

  * GetTrackedFiles: returns the mtime/size map used by the pipeline
    to determine which files need reparsing.

  * SaveSession: transactional upsert of session stats + model
    breakdown + file tracker entry. Uses INSERT OR REPLACE to handle
    both new files and files that changed since last parse.

  * LoadAllSessions: batch-loads all cached sessions with a two-pass
    strategy — first loads session rows, then batch-loads model data
    with an index map for O(1) join, avoiding N+1 queries.

  Uses modernc.org/sqlite (pure-Go, no CGO) for zero-dependency
  cross-platform builds.
