- Added a `followups` CLI command in `scripts/session-stats` for hashline edit follow-up analysis.
- Added `--max-fix`, `--max-gap`, `--min-dup`, `--pattern`, and `--show` options in `cmd_followups.rs`.
- Added follow-up heuristics for small fixes, tool self-corrections, overlapping re-edits, and payload/anchor duplications.
- Updated Rust dependency manifests in `pi-natives` and `session-stats` to newer versions of rayon, tiktoken-rs, tree-sitter grammars, and supporting crates.
- Synchronized `Cargo.lock` with the manifest updates, including package bumps for fancy-regex, serde_spanned, toml components, and winnow.
- Refreshed `package.json` and `bun.lock` catalog and lock entries for newer Bun, AWS SDK, AI, and tooling package versions.
- Added timestamp and model fields to message and tool-call structs with serde defaults.
- Added timestamp parsing and bucket-format helpers, including clamped percentile calculation.
- Added rolling-window call grouping and CSV export via new `--by`, `--top`, `--tool`, and `--calls-csv` options.
- Added `TOOL_CALLS_CSV` env fallback and help text updates describing new bucketed percentile output.
- Lowered the default session scan limit for edits and tools from 100000 to 1000 and updated usage text to match.
- Reworked grand-total and per-tool table rendering in session-stats to compute aligned column widths and include an aggregated "(N others)" row.
- Tuned the session-stats release profile by replacing full stripping with line-tables-only debug symbols and disabled split debuginfo stripping.
