chore: bump version to 0.3.0

The stadium bubble previously dropped the 5h reset countdown (only the
ring + percent were visible in the head) and never showed the 7d percent
as a number (only the tail bar fill suggested it). Two more glanceable
data points now live on the bubble face without reopening the panel.

Head: the small "5h" tag is replaced by the live 5h countdown (e.g.
"2h14m"). Falls back to the literal "5h" when no countdown is available
yet (cold start) or when the localized string would overflow the rect —
DT_NOCLIP would otherwise leak wide CJK glyphs ("4시간 32분") onto the
ring stroke at the 140-logical minimum width.

Tail: a new "X%" reading sits between the "7d" label and the bar
(layout reads "7d  62%  ▰▰▰▰▰▱▱▱   6d4h"). Foreground text color —
not the bar accent — because Codex teal #10A37F on the light theme
background only hits ~3.2:1 contrast, below WCAG AA for small text;
adjacency to the bar carries the visual grouping without hue. The text
brightens in sync with the bar fill when weekly_pct >= 95%.

compute_bubble_layout reserves room for a "100%"-sized rect between
label and bar; if that would push the bar below the 20-logical
minimum, the % rect collapses to zero width and the layout falls back
to the original label→bar→countdown geometry, so the 140-logical
bubble keeps its bar.

No new graphics dependencies; tiny-skia + GDI hybrid render path
unchanged. session_text plumbing in src/app.rs was already wired but
unused in the render — now consumed.

cargo check: clean. cargo test: 2/2. cargo clippy: 13 warnings
(unchanged baseline).
