docs: Fix broken references and remove non-existent flags

[arimxyer]

Clean up documentation by fixing broken links and removing references to flags that were never implemented.

Fixed Broken References

• README.md: docs/05-development → docs/06-development (2 occurrences)
  • Git workflow and contribution guidelines links now point to correct location

Removed Non-Existent Flags

--no-keychain (never implemented)

Before:

pass-cli init --no-keychain  # Disables keychain

After:

• Updated to use interactive prompts during pass-cli init
• Replaced with actual OS credential manager commands for removal:
  • Windows: cmdkey /delete:pass-cli
  • macOS: security delete-generic-password -s "pass-cli" -a "$USER"
  • Linux: secret-tool clear service pass-cli vault /path

--no-audit (never implemented)

Before:

pass-cli init --no-audit  # Disable audit logging

After:

pass-cli init --enable-audit  # Enable audit logging (disabled by default)

Files Changed

• README.md - Fixed 2 broken path references
• docs/01-getting-started/quick-start.md - Removed --no-keychain and --no-audit, corrected to interactive prompts and --enable-audit
• docs/03-reference/command-reference.md - Replaced --no-keychain with OS-specific commands

Verification

./pass-cli init --help
# Shows actual flags:
#   --use-keychain (enable keychain)
#   --enable-audit (enable audit)
#   --no-recovery (skip recovery phrase)
# No --no-keychain or --no-audit flags exist
