Android / Termux + TalkBack reconnaissance

[digitalby]

Termux renders into a custom `View`, not `EditText`, so TalkBack sees nothing. Multiple upstream issues document this:

• termux and accessibility termux/termux-app#1797
• Proposal for adding accessibility in Termux termux/termux-app#4175
• [Feature]: Enhancing Termux Accessibility for Visually Impaired Users termux/termux-app#4304
• PR Improve accessibility of the Terminal View by making Reading Mode navigation more intuitive and add accessibility actions for the context menu termux/termux-app#4104 (partial reading-mode)

Research whether there is any workable path for `acc claude` on Termux (short of running `espeak` in Termux while SSHing out to a Linux box with Fenrir). Track upstream progress and document viable setups.
