Release notes

FEATURE

Accurate offline estimates, fixed beta updates, and crash-free terminal UI

When you're working offline without internet, the system now smartly estimates your costs using the real price list you fetched last week, instead of wildly falling back to ancient factory-default prices and skewing your budget. If you're an early adopter running beta versions, the update checker now understands version numbers ending in "beta", delivering update prompts correctly instead of throwing an error and playing dead. Also, when viewing your session history in the terminal, if a specific entry happens to lack cost data, it now gracefully displays "--" rather than crashing the entire table. It's like traveling abroad without data: you use the exchange rate you saved a few days ago instead of blindly relying on a ten-year-old guidebook; and if a couple of items on your grocery receipt are missing price tags, the whole cash register doesn't explode.

**Pricing falls back to a stale cache when offline**: the fallback order in `pricing.py` is now fresh cache → network fetch → stale cache → hardcoded fallback. Previously a >7-day-old cache combined with no network dropped straight to the hardcoded prices, skewing cost estimates; the real (if stale) historical cache is now preferred.
**Update check now handles pre-release versions**: `update_checker._parse_version` now strips pre-release / build suffixes via regex, so `0.11.0-beta.1` / `0.11.0+build.5` no longer return `None` and no longer make `compare_versions` raise. Beta testers receive update prompts correctly. No new package dependencies were added.
**TUI session table no longer crashes on `cost_usd=None`**: widened `ui/tables.py:_fmt_cost` to `float | None` so entries written without a cost (a known path on the Codex side) now render as `--`, matching the popover-side behavior in `panels/web_panel.py`. Previously the `>=` comparison raised `TypeError` and broke the whole table.
