Fix mustache workaround only taking top level keys into account

Fix broken ids when project or registry names start with the same text.

maybe restructure the new fuction for better readability?
something like

def insert_into_dict(d: dict, parts: list) -> None:
    """Inserts nested keys and value into a dictionary."""
    *keys, last_key, value = parts
    for key in keys:
        d = d.setdefault(key, {})
    d[last_key] = value

same for the original "fill_template" function. I don't want to criticize your programming but its very hard to read.

maybe something like, just as a possibility

import re
import chevron

async def fill_template(client, path: str, logger) -> str:
    """Reads a template file, replaces placeholders with fetched IDs, and returns the updated content."""
    with open(path, 'r') as file:
        config = file.read()

    placeholders = re.findall(r'{{\s*(?:project|registry):[\w.\-_]+\s*}}', config)
    logger.info("Found id templates", extra={"placeholders": placeholders})

    replacements = {}
    for placeholder in (p.strip(" {}") for p in placeholders):
        placeholder_type, placeholder_value = placeholder.split(':')
        replacement_value = await fetch_id(client, placeholder_type, placeholder_value)

        # Create nested dictionary structure for replacements
        insert_into_dict(replacements, placeholder.split('.') + [str(replacement_value)])

    return chevron.render(config, replacements)

and maybe we could include the change from nuitka to pyinstaller in this. its a very small change that safes a lot of pipeline runtime
