Documented new TUI Context tab

[opencode-agent[bot]]

Docs Needed

• 6e7fc30f9 feat(app): context window window introduces a new user-facing Context tab in the TUI session UI (clickable context usage indicator + tab showing token/cost/context breakdown, system prompt, raw messages). This was not documented in packages/web/src/content/docs/*.

Docs Updated

• Added a new “Session context” section describing the Context tab and how to open it: packages/web/src/content/docs/tui.mdx:30.

No Docs Needed

• 03733b050 fix(util): checksum defensiveness / d1a4295a3 fix(util): checksum defensiveness: internal robustness, no user-facing change.
• 6341ed506 fix(app): update primitive colors / ed745df37 fix(app): update primitive colors: visual tweak; not a new feature/API needing docs.
• 01237c532 release: v1.0.223, 41f9a58c2 ignore: update download stats 2026-01-01: release/meta changes, no docs update required.
