agentacct 0.8.0

Added

• agentacct tui just opens for a global install. The read commands (tui, now, limits) now fall back to the machine-wide store when run from a directory with no project store, so a global-by-default install no longer needs --store-dir. A per-repo install still sees its project store, and an explicit --store-dir / AGENTACCT_STORE_DIR still wins — a misconfigured one now surfaces its error instead of silently reading the global store. (#52)
• A cohesive theme and a real nav bar. The TUI ships a cohesive dark theme and a prominent top nav bar — the brand and the current screen, under an accent rule — in place of the thin default header, so usage, cost, and work read as one designed dashboard. (#52)
• One-key shareable snapshot. Press p from any screen to save a shareable SVG of the current view — it renders in any browser or on GitHub — written under the store, never the working directory. (#52)
• The weekly-plan plan column on the sessions list. The full sessions list (press s) now carries the same weekly-plan % column as the home panel. (#52)

Changed

• The weekly-plan estimate is shown only when it is calibrated to your own usage. A per-session "% of weekly plan" now appears only when it is calibrated from your own recorded limit history; otherwise the session detail shows a "calibrating from your own usage" note and the list shows —, instead of a number derived from a shipped universal baseline. Providers change how many tokens a plan grants, so the figure is grounded in your account or withheld. Generalized to every plan-bearing client. (#52)
• Refreshed the README screenshots — the new theme, the plan column, per-step machine-check evidence with exit codes, and the plan-estimate line — and added scripts/gen_tui_screenshots.py to regenerate them from synthetic demo data. (#52)
