fix(input): allow escape as a prefix-mode keybinding

[fraidev]

Hey!

Esc always canceled prefix mode before keybinds ran, so copy_mode = "prefix+esc" (like tmux bind Escape copy-mode) never worked even though the config accepted it.

This treats Esc as a normal prefix RHS when bound; unbound Esc still cancels prefix mode.

Happy to adjust anything if needed.

📝 Walkthrough

Walkthrough

Escape now supports configured prefix-mode bindings through esc or escape. Unbound Escape still exits prefix mode. Tests cover parsing, dispatch, fallback behavior, and copy-mode entry. Documentation describes the updated behavior in English, Japanese, and Chinese.

Changes

Escape prefix bindings

Layer / File(s)	Summary
Escape key alias parsing src/config/keybinds.rs	Tests verify case-insensitive esc and escape aliases for prefix bindings.
Prefix dispatch and fallback src/app/input/navigate.rs	Prefix handling dispatches configured Escape bindings before using unbound Escape to exit prefix mode. Tests cover copy-mode entry and cancellation.
Documented Escape behavior docs/next/CHANGELOG.md, docs/next/website/src/content/docs/*/configuration.mdx	The changelog and configuration guides document Escape aliases, prefix bindings, and fallback behavior.

Greptile Summary

This PR allows Escape to act as a configured prefix-mode RHS while preserving cancellation for unbound Escape.

• Removes unconditional early cancellation so existing prefix-action dispatch can match Escape.
• Adds runtime and configuration tests for esc and escape aliases.
• Documents the behavior in the changelog and translated configuration guides.

Confidence Score: 5/5

The PR appears safe to merge with bound and unbound Escape paths behaving as documented.

Prefix-mode Escape now reaches the existing binding precedence before the unchanged cancellation fallback, while input lease handling prevents repeats or releases from executing an additional action.

Important Files Changed

Filename	Overview
src/app/input/navigate.rs	Defers Escape cancellation until after prefix binding dispatch and tests both bound and unbound behavior.
src/config/keybinds.rs	Adds coverage confirming case-insensitive esc and escape aliases produce an Escape prefix trigger without diagnostics.
docs/next/website/src/content/docs/configuration.mdx	Documents Escape aliases, bound prefix behavior, and unbound cancellation.
docs/next/website/src/content/docs/ja/configuration.mdx	Updates the Japanese configuration guide with the new Escape prefix-binding behavior.
docs/next/website/src/content/docs/zh-cn/configuration.mdx	Updates the Simplified Chinese configuration guide with the new Escape prefix-binding behavior.
docs/next/CHANGELOG.md	Records the corrected Escape prefix-mode dispatch behavior.
