feat(display): add include_cwd_prefix toggle (#1221)

[Kevsosmooth]

Implements #1221.

Adds a [display] include_cwd_prefix config knob (default true) that gates the [<cwd-basename>] prefix on the terminal title (set-titles-string). The default preserves the current [<project>] <name> format; set it to false to show only the session title.

Per the issue thread, the prefix is gated at the single place the title is formatted (buildTerminalTitleArgs), driven by config resolved once at startup.

Changes

• DisplaySettings.IncludeCwdPrefix *bool + GetIncludeCwdPrefix() — defaults to true.
• internal/tmux: package-level hideCwdPrefixInTitle flag gates the set-titles-string value; SetHideCwdPrefixInTitle(...) is called once at TUI startup from cfg.Display.GetIncludeCwdPrefix().
• Tests: getter default, TOML decode of the new key, and the title builder emitting the prefix on/off.

Behavior

Default is true, so existing setups are unchanged. To opt out:

[display]
include_cwd_prefix = false

Summary by CodeRabbit

• New Features
  • Added new configuration option include_cwd_prefix to control whether terminal and pane titles include the current working directory basename prefix. This setting defaults to true for backward compatibility and can be disabled to display cleaner terminal titles with only the display name.

📝 Walkthrough

Walkthrough

This PR adds an optional TOML configuration setting include_cwd_prefix to DisplaySettings that controls whether tmux terminal titles include a [<project>] prefix. A getter defaults the setting to true when unset. An atomic flag in tmux receives this setting during UI initialization and buildTerminalTitleArgs() conditionally omits the project prefix from the title string based on the flag state.

Changes

CWD prefix title configuration

Layer / File(s)	Summary
Display settings schema and getter internal/session/userconfig.go, internal/session/userconfig_test.go	DisplaySettings adds an optional IncludeCwdPrefix TOML field with TOML key include_cwd_prefix. GetIncludeCwdPrefix() returns true when the field is unset (nil), otherwise the configured value. Tests verify the getter default and explicit true/false behavior, as well as TOML decoding.
Tmux title formatting with configurable CWD prefix internal/tmux/tmux.go, internal/tmux/tmux_test.go	A package-level atomic boolean hideCwdPrefixInTitle with setter SetHideCwdPrefixInTitle(bool) enables concurrent configuration. buildTerminalTitleArgs() conditionally omits the @agentdeck_project_name prefix from set-titles-string when the flag is enabled, using only @agentdeck_display_name. Test coverage validates the title output toggles between "[#{@agentdeck_project_name}] #{@agentdeck_display_name}" (default) and "#{@agentdeck_display_name}" (prefix hidden).
Configuration wiring in UI initialization internal/ui/home.go	During NewHomeWithProfileAndMode setup, the display config is applied to tmux by calling SetHideCwdPrefixInTitle(!cfg.Display.GetIncludeCwdPrefix()), binding the user setting to the title formatting behavior.
