Per-directory config override for project/board

[JLugagne]

Is your feature request related to a problem? Please describe.

I work on a few different Jira projects within the same org. The auth, server, login, etc. are the same everywhere — only the default project (and sometimes the board) changes depending on what I'm working on.

Right now to switch projects I have to either pass -p PROJ on every command, duplicate my full config and use --config/JIRA_CONFIG_FILE, or set up direnv. Duplicating the full config is annoying because if I rotate my token or change anything else, I have to update every file.

Describe the solution you'd like

Look for a .jira-config.yml in the current directory and walk up until one is found, like git does with .git/. If found, merge it on top of the global config — local values win, missing values are inherited.

Typical local file would just be:

project:
  key: PROJ
board:
  name: My board

No need to repeat server, login, auth_type, etc.

Describe alternatives you've considered

• -p on every command — tedious, and doesn't cover the board
• Full config duplication via --config / JIRA_CONFIG_FILE — works but painful to keep in sync
• direnv — works but needs an extra tool

I've started a PR for this, fill free to comment it

While this is a nice and valid feature request, I feel that the JIRA_CONFIG_FILE is enough when coupled with mise or direnv (as you also pointed).
So IMHO not really worth the effort of maintaining the new code that looks for the config on the cwd (and traverse up indefinitely).

Btw: this reminds of rg (ripgrep), which doesn't automatically attempt to check any configuration file unless a RIPGREP_CONFIG_PATH environment variable is set (source).
