Refine ExtractIssuePrefix to better distinguish hash IDs from English
words in multi-part issue IDs. Hash suffixes now require digits or be
exactly 3 chars, preventing "test", "gate", "part" from being treated
as hashes. This fixes prefix extraction for IDs like "vc-baseline-test".
Also updates git hooks to use -q flag and adds AGENTS.md documentation.

The ExtractIssuePrefix function was falling back to first-hyphen
extraction when the suffix didn't look like a hash (e.g., 4+ char
words without digits). This broke prefixes like 'hacker-news' where
an issue ID 'hacker-news-test' would incorrectly extract 'hacker'.
Fix: Always use last-hyphen extraction for alphanumeric suffixes.
Only fall back to first-hyphen for non-alphanumeric suffixes.
Examples:
- 'hacker-news-test' -> 'hacker-news' (was: 'hacker')
- 'me-py-toolkit-abc' -> 'me-py-toolkit' (was: 'me')
- 'vc-baseline-hello' -> 'vc-baseline' (was: 'vc')

isLikelyHash() required at least one digit to distinguish hashes from
English words, but base36 hashes can be all-letters by chance.
This caused ExtractIssuePrefix("xa-adt-bat") to return "xa" instead
of "xa-adt", breaking import for 20 issues in xa-adapt.
Fix: Accept all-letter suffixes for 3-char only, keep digit requirement
for 4+ chars where word collision probability is low enough (~0.2%).
Rationale:
- 3-char: 36³ = 46K hashes, ~1000 common words = ~2% collision
- 4-char: 36⁴ = 1.6M hashes, ~3000 words = ~0.2% collision
- 5+ char: collision rate negligible
- Lower minimum hash length from 4 to 3 characters
- Update hash validation to support base36 (0-9, a-z) instead of just hex
- Require at least one digit to distinguish hashes from English words
- Fixes prefix extraction for hyphenated prefixes with 3-char hashes
e.g., 'document-intelligence-0sa' now correctly extracts 'document-intelligence'
- Add test cases for 3-char hashes with multi-part prefixes
- Resolves bd sync failures with 'prefix mismatch detected' errors
Fixed bug where issue IDs with multiple hyphens in the prefix and hash
suffixes were incorrectly parsed. For example, `web-app-a3f8e9` was
being parsed with prefix `web-` instead of `web-app`.
Root cause: ExtractIssuePrefix() only checked for numeric suffixes.
When it encountered a hash suffix, it fell back to using the first
hyphen instead of the last hyphen.
Changes:
- Added isLikelyHash() helper to detect hexadecimal hash suffixes (4-8 chars)
- Updated ExtractIssuePrefix() to handle both numeric and hash suffixes
- Added comprehensive test cases for various prefix patterns
Test coverage includes:
- web-app-123 (numeric suffix)
- web-app-a3f8e9 (hash suffix)
- my-cool-app-a3f8e9 (three-part prefix with hash)
- super-long-project-name-1a2b (four-part prefix)
- Various hash lengths and case variations

The ID disambiguation logic treated 'offlinebrew-3d0' as ambiguous when
child IDs like 'offlinebrew-3d0.1' existed. Now the system:
1. Checks for exact full ID matches first (issue.ID == input)
2. Checks for exact hash matches (handling cross-prefix scenarios)
3. Only falls back to substring matching if no exact match is found
Added test cases verifying:
- 'offlinebrew-3d0' matches exactly, not ambiguously with children
- '3d0' without prefix still resolves to exact match
