The Ctrl+O thinking-pager arm guarded on
`key.modifiers == KeyModifiers::CONTROL` (exact match), so any
additional modifier bit set by the terminal — Shift while a
native-selection mouse bypass was active, Caps Lock indicator on
some keyboard layouts — silently fell through to the $EDITOR arm at
ui.rs:2833 and did nothing visible when the composer was empty. The
user saw the "thinking collapsed; press Ctrl+O for full text"
affordance, pressed it, and the handler appeared to ignore them.
Relaxed to `contains(KeyModifiers::CONTROL)` to match the established
pattern at Ctrl+P (ui.rs:2068) and Ctrl+B (ui.rs:2077). With the
existing `app.input.is_empty()` guard preserved, the $EDITOR arm
still owns the non-empty-composer case, so the two handlers continue
to partition Ctrl+O cleanly.
Also documents the two-binary install gotcha in AGENTS.md: the CLI
dispatcher (`crates/cli` → `deepseek`) and the TUI runtime
(`crates/tui` → `deepseek-tui`) ship as separate executables, and
`cargo install --path crates/cli` alone leaves the TUI stale — which
is how both this fix and the active_cell fix from dc2433a8b
initially appeared to be no-ops during local maintainer testing.
The release pipeline packages both binaries, so end users were
never affected by that side; this is purely a maintainer-local
footgun and is now spelled out for future agents.
Extends the existing v0.8.29 CHANGELOG entry to credit both halves
of the Ctrl+O fix.
