Enforce LF line endings for .devcontainer/.bashrc

[jestinjoshi]

What

Adds a .gitattributes rule to enforce LF line endings on .devcontainer/.bashrc.

Why

On Windows, .devcontainer/.bashrc was checked out with CRLF line endings because no .gitattributes rule covered it. Inside the dev container, bash then fails to load it:

/root/.bashrc: line 2: $'\r': command not found
/root/.bashrc: line 7: syntax error near unexpected token `$'{\r''

This breaks the custom shell prompt (the git_branch/git_status_marker helpers) for anyone developing on Windows via the dev container.

Fix

.devcontainer/.bashrc text eol=lf

This follows the existing convention in the same file (bin/*, *.sh, *.rb are already pinned to eol=lf for the same reason).

Safety / impact

• The committed blob is already LF, so this changes no file content — the PR is a single line in .gitattributes.
• macOS/Linux contributors: no change (already LF).
• Windows contributors: the file is silently re-checked-out as LF, which is correct since .bashrc is consumed only by Linux bash inside the container.

Poem

A bashrc file sat in its devcontainer nest,
Its line endings wandered — that wasn't the best.
One hop, one rule, one line in the file,
Now LF keeps order with bunny-eared style! 🐇
Git attributes rejoice down the mile!

In @.gitattributes:
- Line 18: The gitattributes rule correctly targets .devcontainer/.bashrc, but
docker-compose.yml has a broken mount configuration that tries to mount
./.bashrc (which does not exist at the repository root) into the container. To
fix this, update the mount configuration in docker-compose.yml to reference
.devcontainer/.bashrc instead of ./.bashrc, or alternatively create and commit a
.bashrc file at the repository root for the container to use. Choose whichever
approach aligns with your project's intended structure.

[jjmata]

Good catch and a clean fix — the .bashrc extension-less filename falls through all the existing wildcard rules (bin/*, *.sh, *.rb), so an explicit entry is the right approach.

One thing worth considering: .devcontainer/ may grow other shell-executed files over time (setup scripts, entrypoints, etc.). A slightly broader rule like

.devcontainer/* text eol=lf

would cover the whole directory without needing per-file entries. The current single-file rule is perfectly fine for now — just flagging the option in case you'd prefer to be more future-proof without adding a bigger change.

Otherwise this is correct, minimal, and consistent with the existing conventions in .gitattributes. 👍
