[Bug]: File scanner (initial or subsequent) ignores all files because of wrong interpretation of .gitignore

[smuuf]

Bug Description

File scanner/indexer (initial or subsequent) ignores all files because of (what I think is) wrong interpretation of .gitignore:

I have this in my repo's root .gitignore:

# Ignore all dot-directories in the repo root.
/.*/

... which tells git to ignore all directories with names starting with . located in the repo root. Works as it should.
But I think that grepai interprets it wrongly and then this happens:

[smuuf@smuuf-hp]$ grepai watch
Starting grepai watch in /my/lovely/project
Provider: ollama (nomic-embed-text)
Backend: gob
RPG: disabled
2026/02/20 16:04:08 Watching project: /my/lovely/project (backend: gob)

Performing initial scan...
Initial scan complete: 0 files indexed, 0 chunks created, 0 files removed, 0 skipped (took 0s)
Building symbol index...
Symbol index built: 0 symbols extracted

When I comment it out:

# Ignore all dot-directories in the repo root.
# /.*/

... then grepai properly starts to index files in my repo:

[smuuf@smuuf-hp]$ grepai watch
Starting grepai watch in /my/lovely/project
Provider: ollama (nomic-embed-text)
Backend: gob
RPG: disabled
2026/02/20 16:12:56 Watching project: /my/lovely/project(backend: gob)

Performing initial scan...
Indexing [███████████████░░░░░]  76% (2269/2993) ...vents/blablabla.php

Steps to Reproduce

1. Have a project with some files.
2. Put .gitignore with line /.*/ in the project's root.
3. Run grepai init; grepai watch
4. Nothing is scanned.

Expected Behavior

grepai shouldn't interpret having /.*/ in gitignore as "ignore everything" and should scan/index the project as expected.

Actual Behavior

grepai skipped/ignored all files in the repository and scanned/indexed 0 files.
